    Taken from La Palma at a place on the South West of the island called "Los Llanos Negros" (after the colour of the volcanic soil here), at an altitude of about 360m amsl. I took this last night while waiting for my primary target to rise above the volcano. Equipment as in my signature mounted on a sawn-off, flight-friendly, HEQ5. R 3*120s G 5*120s B 4*120s I'm not really sure how I ended up with two more greens than reds, but that's what I got! Processed in PI on my trusty £140 ebay laptop. I used the R,G and B to create a synthetic L, processed and de-noised the RGB and then did an LRGB combination. I think it turned out rather well considering the short integration time and there'e even a hint of dust, which just goes to show what a proper dark sky does for you!

    Well short because it was a short session. Short because some idot forgot his boots and thick socks so had to call it shorts because his feet were like blocks of ice Anyway, skies were clear, great seeing and very steady. WOf the things I viewed the ones that stood out were: Saturn nebula. Definite colour in it at around x80, a sort of blueish, maybe turquoise tint although a little less prominent as i cranked it up but really looked good. (and a first). Saw several other plenetary's including the turtle although it was the saturn who was pick of the bunch. Dumbbell looked magnificent last night with a UHC, sat in a pool of stars and seemed much more interesting than using OIII filter. Great structure, simply beautiful. Also got some decent nebulosity from the Pleiades, seen it better but last night was second best so very pleasing too. M31 Andromeda was quite obliging in giving up some of her spiral detail as was M33 although the latter less so much. Veil nebula (6995 side, left as viewed ) fantastic. OIII really lifted out great structure from this. Filaments, shades and shape. Really turning into one of my favourites. Best view so far last night. North American Nebula. No doubting with this, simply jumped out from the eyepiece when i looked. Thought this was more challenging than it was but gave itself up to the 26mm Nagler fitter with the OIII filter easily, Shape was there and some structure of sorts although it wasn't fantastic. But hey, she was there for sure. HB filter seemed to give no more than the OIII. (another first) Last and yet another first. California nebula. Harder than the N.AM neb by some margin. Had to move the scope slowly from side to side where the nebula was and slowly built up an image of it. There was some shape but it wasn't defined and no structure at all. Little more than a brightening of the sky really and was using HB filter. That all really. Saw plenty of other stuff but I couldn't settle for too long dues to cold feet. So most of the above views were limited to a few minutes although the better ones lasted a while longer. Damn my forgetfulness.

    This is a joint venture with Mr and Mrs Gnomus whose company I'm enjoying this week. We let the tandem Tak run for three nights on NGC1499, hoping to find outlying dust and, to our delight, we found some. The details: L 7.5 Hrs in 20 min subs. RGB 3 Hrs per filter, 15 min subs. Ha 11.5 Hrs, 30 min subs. OIII 7.5 Hrs, 30 min subs. And then a lot of processing.... Ha mapped to red, OIII to green and blue and a tiny touch of Ha to L as well. Click on the image and the full size button should be lower left. Olly, Steve and Lis.

    Here's last night's result, the Pacman Nebula NGC 281. This picture was a stack in DSS of the best 85% of 96 frames taken last night, then processed in photoshop following advice gleaned on this forum. I took had to lose about 20 others that were badly obscured by cloud. Each frame was 120 seconds at 800 iso. I used flats, darks and bias frames and no doubt the cold temperature helped keep the noise down. The telescope is a 130P-DS. My camera is an astro-modded Canon 450D, but this object is bright enough you should be able to image it on most DSLRs.

    My daughter got home at about 7 last night, and noticing that it was clear, as soon as she got through the door: "daddy , can I have look through your telescope?" I'd already planned to go out with it, as the forecast was to be clear all night, so I quickly set it up to show her some of the wonders. She struggled to see anything with my 14mm Morpheus - not sure why, probably not getting her eye in the right place - so I stuck in the 24mm ES, which she had better luck with. This is what we looked at: Albireo, which got her very excited to see the different colours. Double Cluster, which got a bit of a gasp at the number of stars she could see. M31, which got a bit of a "meh!", so i tried explaining how far away it was and that it was a whole other galaxy. She then got distracted by the fireworks, which didn't do the transparency any good, and she started to get cold as she wouldn't put a coat on! I tried to show her M13, but it was really low down in the murk and not very impressive. She then went to bed and I had some dinner before heading back out for another hour (before the cold and dew got to me). I only had two more targets, both of them new to me: Uranus, it was nice to eventually track this down; very distinctly not a star, and with a bit of power I started to draw out a bit of a light greeny/blue colour, couldn't seen any moons though. Blue Snowball, this was another one that I'd previously had trouble finding, but I think a bit of experience is starting to show in hopping to the targets and I found it pretty easily. Spent a bit of time on this, changing up magnification and swapping out filters, but never really got much more than a small fuzzy ball, possibly a hint of blue, but that could have been imagination - i don't think the firework smoke was helping.

    I took this from an upstairs open window this evening. It wasn't until I processed it I realised I'd just about caught Saturn as well. You need to look carefully to see it though. Hope you like it.

    Got home in my hired motorcaravan this afternoon. A sunny day, light traffic and the wonderful autumn colours made for a rather pleasant drive. Sadly, no pictures of the sky, even though I waited with my dripping wet dslr until midnight last night. I did take one photo in my motorcaravan, though. A small consolation. Allan

    M27 captured from AstroCamp in Nerpio, Spain using iTelescope's T18, a 318mm PlaneWave CDK. First I collected about 5h minutes exposure in H-alpha, SII and OIII. Then I added some 2h Lum and 3h RGB bin2 for a total of a touch more than 10 hours. I think it turned out ok, especially with fairly natural colours but good definition of the internal structure from the narrowband data. Cheers, Michael

    A while ago my friend's wife asked me to recommend a telescope for her to get him for his 60th birthday earlier this year. He's not a stargazer but has a passing interest in the night sky. My recommendation was to not bother, he's already got a nice pair of bins for stargazing and he'd struggle to get to grips with a scope. Anyway, "no" was not an acceptable answer so I thumbed through the pages on FLO's website and after some weighing up of the benefits v complexity of Goto I settled on the Celestron Nextstar 127 SLT . The good lady was looking to spend considerably more than that but it wasn't justifiable . She duely ordered it from FLO. So fast forward to last weekend when I final saw he'd taken it out of the box up here in Rural Cumbria where we both have luxury villas on the same site. Unfortunately the sky wasn't playing ball and he was going home on Sunday whereas I'm up here all week on my holidays. He suggested I could put it through its paces during the week if the sky improved and I'd then have expert knowledge to train him with Tonight was that night. Good clear sky but not as dark here now as it used to be. Did I mention the girls? Oh, right. Well during the summer we finally qualified as foster carers, the MD having taken voluntary retirement after 33 years in the same job for just that purpose . Our own son flew the nest a few years ago and is independent and self sufficient . Our 4 bed house needed refilling! The phone call to tell us we were now qualified after 9 months of procedure was also to ask us if we had room for 2 sister, 10 and 13 years old. To cut a long story short they arrived a week later with their baggage, all their baggage. Emotional and material. We're 2 months into this new way of living and I've been very busy! Luckily they like it up here, after all, there is WiFi and lazy days When I said the sky was good for testing my mates new scope I instantly had 2 volunteer helpers. I was trying to discourage them, concerned that they'd just get bored out into the cold. Actually I was concerned about clumsy limbs causing damage to a brand new telescope that isn't even mine. I was outvoted. The girls joined me down the track. They both flashed their torches in my face to acknowledge their understanding of my first rule of stargazing. "never shine torches in a stargazers dark adapted eyes" . . . Things weren't looking too promising The scope was already assembled in the lounge of his luxury villa so I carried it out and very roughly leveled the the azimuth with the tiny bubble level on the tripod . I got the lat and long from my "current location" via SkySafari on my phone. I wasn't familiar with the Skyalign process but I'd read the quick setup booklet and had an idea what to do. Just point it at 3 bright stars (or solar system objects apparently ) and center them before hitting the "align" key. I had some restriction in view to the south and east but selected Vega, Altair and Capella. The girls were suitably impressed by me pulling star trek names out of thin air! I should mention my poor relationship with finders. Never used one, ever. The straight through telescopic ones that came with both my own Newts have never been used . I never liked the contortions required to use them. This scope came with a red dot finder but I couldn't be bothered aligning it with the scope for fear of the girls getting bored even sooner than expected. I prefer to just sight down the telescope tube. It's what I've always done and is second nature. During this 3 star alignment I was pointing things out to the girls. They said they could see the milky way but I wasn't convinced until their eyes became dark adapted then one of them exclaimed their surprise when they actually did see it, followed soon after by the other one. I knew they could see it when they described the Cygnus Rift. They'd never seen it for 2 reasons. One being the light pollution where they used to live and the other being the circumstances of where they used to live . Bit of a moment for us all I thought and I was going to deny them this! Right, so all 3 stars aligned but when I clicked to complete the process I was informed it had failed I guessed I'd set the daylight saving time wrong. I was right it was wrong. A quick second round of star alignment had success . But where to next? These young eyes would be expecting blazing supernovae and ringed planets to be displayed in sharp contrast in the eyepiece . OK, ringed planet it is. After a few puns about Uranus I had the Goto purring off towards the tree line. Luckily Uranus was just above them and I was pleased to find it almost central in the field of view of the supplied 25mm eyepiece! A quick focus gave a reasonable image though seeing was a bit wobbly. I could see a disk but I knew the girls wouldn't so I changed to the supplied 9mm eyepiece and focused that. Definitely poor seeing and the focus was a bit soft. Not a brilliant eyepiece I'm thinking. I let the girls have their first look , all the time reminding them of the importance of not kicking the tripod legs or leaning against the telescope . I was also mindful of the task I had set them. Their first ever view through a telescope using a narrow field of view with less than easy eye relief on a difficult subject. Eventually they saw something blue or green and enjoyed describing it. I put the 25mm eyepiece back in and focused it. They both preferred that view. I did all the focusing but kept my specs on hoping it would be nearer to focus for them. I wanted to avoid them trying to focus for themselves so early in their careers. Next, one of my favorite objects, M13, the Hercules Globular. With the 9mm I thought the focus was soft again but with the 25mm it was quite nice. Just as I remembered it, a scintillating fuzzball . The girls described what they saw very well. The enormity of what they were looking at was far beyond their grasp but they liked it. Even though feet and hands were getting cold. 1deg C forecast for overnight. They wanted to see the milky way through the telescope but I know that can be underwhelming if the observer doesn't take time to focus both optically and mentally. Next best thing I could think of was the Double Cluster in Perseus . Good choice, it just about fit in the 60x field of view and it was beautiful. This is what they wanted all along! Time was running out, junior's bed time was approaching and they were now definitely chilled. The sky clarity was diminish too, it seemed. I hoped for more from M81/82. The lights of Penrith were washing out the contrast. The girls could see them but they were not impressed . What about Albireo I thought. They might like the colours. It landed in the center of the field of view and looked pretty. I always have the colours as yellow /orange and blue. They both described amber and green. So near enough. They liked that. One last goto then time time to pack up. M57, the Ring Nebula might be OK I thought. And it was. Good contrast too. The girls described it extremely well. They discerned the colour and the shape accurately. Unbelievable for their first session. But time has flown. An hour and a half was enough for us all. Senior headed back the warmth and junior was chief torch bearer while I packed up. So what was going to be a test run and first light for the telescope turned out to be a different kind of first light experience. Two young ladies came away from it having had a very positive experience. They'll be all over my Skywatcher 250PDS back home. Might struggle to reach the eyepiece though. As for this here Celestron 127 SLT, well , I liked it. It's just the right size for my buddy. Might benefit from better eyepieces if he starts getting into it. I see the spec mentions 2 star auto align. I didn't find that mode so don't know what it is. I'll look into it. My buddy will struggle, at least initially with the 3 star alignment. I will set up the finder for him, honest. . . . some day I've already recommended a power supply of some sort . Either the power tank or mains supply. The handful of AA batteries he's currently using won't last too many cold nights of Gotoing. He's back here on Friday so hopefully he'll get his own first light and telescopic experience.

    Typical not a star at SGLXII come home and clear skies (sort Of). Set up 2 star aligned Went to M57 just to see if I could see any colour from the Frac was a bit disappointed until realised had dew luckily had another dew strap so put both on. Next double double this I split easily with 5mm 4 distinct stars. Had to look at the Garnet star(SAO 0336 93) It did not disappoint lovely resolved orange/red star. Auriga NGC 1778 nice rich open cluster plenty of resolved stars,NGC1664(Kite Cluster) all the stars were white found that strange, NGC1907 very compact open cluster two bright stars to one side, NGC 2192 another tight open cluster, NGC 1857 looked like a X to me with bright orange star in the middle, NGC 1893 y shaped cluster could not see any nebulosity, M36,M37,M38 plenty of stars here I think M37 is the best. M38 looks like two small clusters crashing into each other. NGC 457 love this cluster and the colours in the Tal were superb, NGC 869/884 double cluster this blew me away so many resolved stars more than I have ever seen before just jumping out the more a looked highlight of the night. Albireo lovely colours, 16 cygni pair of yellow stars very nice, 17 cygni lovely blue primary and dimmer red companion, 61 cygni great pair orange stars. cloud was building now so went to M81 and M82 got them both in 25mm the cigar was a lot easier to see. Caster wow 8mm should two probably about the same size yellow stars first time seen these. Last but by all not least M42 wish I had put uhc filter on only thought when packed up trapezium had 4 distinct stars but cranked up power 5mm with a little averted vision the 5th popped out and that was it cloud coming in fighting with dew all night but very productive night. I can see me having some great nights with this Scope.

    Clearish night here last night so went for another Elephant hunt! I managed just under 2 hours worth of subs. Taken with a canon 600d through my SW 130 pds at 800. Btw, Photobucket seems to have cropped my main image! gggrrrrrrrrr! And here is a crop with the added data from the other night All mixed and stired in PI with a sprinkle of Neat Image to reduce the noise a little more. Hints and tips welcome

    I happened to acquire 3 hours of luminance on M45 while waiting for my primary target to rise. I have many versions of this from hardly processed to processed very aggressively. This version represents middle of the roadish processing for my data. I am trying to decide if I have pushed the data too far....allot of outlying dust is visible, but with only 3 hours of data, maybe too much. I did have to stretch a bit to get there, Perhaps with more data, and longer subs, the dust will be revealed without stretching to see it. 36 10 minute subs, TVnp101is, STT 8300m with Astrodon series IIE LRGB filters.

    Hi all, I managed to capture the interesting Earth-crossing asteroid 164121 (2003 YT1) last night on its closest approach of around 13.5 times the Earth-Moon distance. So close that it was moving at around 55" per minute, at about mag 11.5 in the constellation of Camelopardalis. It's a 1.1-kilometre-wide Apollo asteroid discovered by the Catalina Sky Survey on 18 December 2003, which has a 200m-wide satellite. It completes an orbit every 427 days in an eccentric ellipse with a relatively high inclination of 44 degrees, which has interesting consequences as tonight it passes just 4.6 arcminutes — less than one-tenth of a degree — from Polaris at 02:30 UT. Here's the result of just 15 x 5 second exposures, field of view 29.9 x 22.5 arcmin. The brightest star on the left is 8.5 mag HD36467 : Stacked in DSS on the asteroid Stacked on the stars Animation

    Just spotted Venus shortly after sunset today before it followed the sun into the horizon. Very low down, but very bright. Despite being low, it was quite easy to spot from a upstairs window which gave a lower horizon. Although not ideal to view out of a window, the scope was quickly grabbed and at 100x I think I detected the gibbous shape leading across the eyepiece. It was jolly wobbly though! Oiii filter used to control the glare and reign in the psychedelic colourfest from the fast frac...! Made for a lovely scene with a thin crescent moon, with the lit side of both facing the sunset. Looks like it's going to improve in the coming months in terms of altitude and distance from the sun, so hopefully some good viewing for everyone.

    I recently went for a week in the North Wales area, mainly concentrating on the Anglesey and Snowdonia area. Thankfully we managed quite a few clear nights and I thought I would share a couple of the astro shots... The first couple are classic shots of the Milky Way going down over Llanddwyn Island (Ynys Llanddwyn), looking South over the Llyn peninsula. 3rd shows what I think is an iridium flare (?). Moving over to the Penmon lighthouse, there was reported aurora possibly visible down to South Wales, unfortunately I did not see it... The next night found us shooting around Llandberis, the Lone Tree at Llyn Padarn was a shot I wanted to try to get, it was good to be able to get a clear view of the summit of Snowden, 2 x 30" exposures of the ISS, also caught a possible meteor and a bit of a photobomb from Andromeda. Moving up the Llanberis pass we dropped down to Llynnau Mymbyr to get shots back toward Snowdon. Rather pleased with the vertical shot, it shows a helicopter rescue on Snowden, a bit of the Milky Way and an interesting streak. For the last night of astro shooting saw us back on Anglesey for another great night. Starting at South Stack, I was trying to get the moonset, Milky Way and the Lighthouse - this was a single 30" shot, I then used my hand to block the bottom of the image which possibly has about a 10" exposure. Finally we moved across to shoot the Lynnon Mill The area has lots of amazing sights for both day and astro shooting, I was really pleased with the results and was really lucky with great locations and interesting skies...

    Returning to some data from last year that I was never able to get to grips with previously, here's a new version of my M31. 200mm lens at f3.5 on a modded Canon 100D, a mix of 60 and 75 second unguided subs for about 1h30m of data in total. I'm definitely much happier with the colour balance now, previously I was struggling against a purplish hue. I've also managed to bring out more of the halo - there is a bit more in the data but it becomes increasingly difficult to separate it from the background. Here's a version with a bit more colour, struggling to decide between them: And a closer crop of the 1st version: Hope you like it. No doubt I'll look at it again tomorrow and want to start tweaking, but for now I'm done.

    Yep it was a good night. Nice milky way overhead and clear although somewhat hazy on and off with intermittent transparent spells. I managed a few new ones, mainly the cocoon nebula in cygnus which was very faint, and a quite distinctive view of the helix nebula in aquarius even though it was low down near the horizon. Oh and almost forgot to mention it but I got the horse head for the first time Then spent some time with Damian and his 22" dob where he bagged the horse head followed by a quick view of the showstoppers like m51 and m42 - the detail with his dob is incredible!

    Although the issue, concerning the removal of silver spots on refractor object lenses was raised in September by the OP. For those interested, here is a little further information on removing this silver spot phenomena from the glass, published by Astrophysics, http://www.astro-physics.com/products/accessories/cleaningproducts/optcs-instructions.pdf Para 5 refers. Probably, like a lot of others, I was not aware that ones own saliva was a powerful cleaning agent to use in such cases, no doubt fingers should be spotlessly clean before attempting this procedure. I am indebted to fellow Mod Michael ( Michaelmorris ) who quoted this pdf in a recent thread, under a separate topic

    I will add my thank you to all the SGL folk who make the star party happen, Daz, Grant, Steve, and all the others, please step forwards and take a bow! I thoroughly enjoyed this one, perhaps more than any other, which is strange given the pants weather. I think the reason is perhaps that this time I didn't come laden with imaging gear, desperate to take the killer pic, to only end up frustrated by the inevitable lack of good conditions. I was there for a good old catch up with old friends and ready to meet new and interesting like-minded people. The meals and activities were spot on (though I'm still sure the sticky toffee pudding was actually treacle pudding, despite the kitchen staff's assurance it said toffee on the packet!). I did get a few hazy views through some scopes (thank you to the various owners!) and even took some images trying out a SW Star Adventurer bundle (thank you Will), so impressed was I by that piece of kit I have placed my order with FLO already. So, thank you all for a great long weekend away and I really hope the Sixpenny Handley idea gets off the ground for next spring. See you all at the next one. Clear skies!

    After posting I went out for a bit longer. Looked at the Hyades and M42. I think the bins are easier on my eyes than a scope, so perhaps binoviewers would help, but not a cheap solution as every eyepiece needs to double up. My eyes are changing rapidly again (early-fifties), like they did in my early forties, so I'm putting off new glasses until they settle as they are still fine for driving. I wonder if this doesn't help? Perhaps when I get new specs and they settle down again things will improve. The next step for now is a comfy chair that I can lean back in, and perhaps lots of short sessions and build up to where I can start to stare into the detail. Thanks for all your ideas and support guys.

    Cheers folks! Here's 10 minutes-worth of 60-second exposures from this evening as it approaches the North celestial pole. A few wobbles in the seeing or guiding, hence the blips in the path. The little spiral galaxy above it is 15th magnitude UGC 3257.

    I've wanted for some time to have a go at the DC with Ha background, yet another image first produced by Fabian Neyer, and I got to it with guests Dave and Darren over the last three nights of last week. With 3 nights spent on Ha in one of the Taks, the parallel one had more than enough data for the standard LRGB rendition. With over 2 hours per filter it would be hard to go wrong, but having more than enough data was nice. So in reagular guise, here's the binocular observer's favourite: In adding the Ha I didn't want to try to replicate Fabian's masterpiece so I kept the Ha down and gave more contrast to the cluster (or to put it another way I did my best with only 14 hours of Ha data in 30 min subs. ) The processing took me into new territory. The brutality of the stretch needed to find the Ha at all meant that the stars became too big, even from the 3nm filter, and affected the star colour in the LRGB, even in Ps blend mode lighten. Some experimnting showed that I could deliberately white clip everything brighter than the brightest nebulosity by dragging the curve above it down to a horizontal line. Of course the Ha then looked horrible but the part I needed was healthy enough and in blend mode lighten it would only be that part that found its way into the image. So here we go. Click on the image and the big one can be had by using the button lower left. By blending the two one can have any level of Ha in the final version so it's a matter of choice. More was available but I stopped at this point. Your opinions welcome! Olly

    27 X 5 min, Canon 1200D, 70-300mm zoom at 166mm, F 5.6, Tracked, DSS, PS, DBE. Ok, it doesn't have the detail, depth or smoothness and colour of a mega long exposure, but it only took me 2 hours and 15 mins, and its not too bad! I feel like i have overdone the smoothing but this camera seems to have a lot of horizontal banding that I have to get rid of/mask. This is despite fantastic seeing last night, the clearest night I've had here in nearly three years of imaging.

    Captured back in early October, I didn't pay quite enough attention to the framing - I should have moved the camera up and right a bit and I could have gotten the whole belt in the picture... the headline stuff is in there though, M42/M43, Horsehead and Flame etc 10x 200 second subs taken with a modified Canon 650D through a Borg 55 f/3.6 (focal length 200mm). There's a load of red stuff in there that needs more exposures (or slightly longer ones) to show more off so I will redo this one and frame it correctly... or do a mosaic of Orion or... well, it'll depend on the number (or lack) of clear nights!! Unfortunately there are haloes on Alnitak and Alnilam, I may have a solution for the next time I cover this area Processing wise I'm going to have to sort out shorter exposures for the Orion Nebula and longer for the rest...

    This image represents my 1 year anniversary doing astro-photography, which I began on 11/3/2015. Thank you all for helping me improve. Though there is a long way to go, I am pleased that I can at last see some reproducible improvement. Televue np101is, SBIG STT 8300M with self guiding filter wheel and Astrodon 3nm NB filters 6 hours each of Ha, OIII, and SII in 30 minute subs. Total 18 hours of exposure. The Ha stack was inserted as a luminance layer, making it a (Ha)SII-Ha-OIII image. Version 1 is softer with less sharpening, and version 2 is a bit more defined, though I think I went a bit too far. Not sure which I like better.

    Folks, whist scanning around for asteroid 164121 this evening I stumbled across this lovely little planetary nebula nearby, NGC 1501 in Camelopardalis. This is just 12 x 5 min exposures, plus 10mins R & B, 2 binned, with synthesised green. No flats, and I've just noticed a big dust bunny in the middle. Oh well. It's very blue, so probably worth a proper session with an OIII filter. Apparently it's sometimes called the Oyster nebula.

    Still here going strong... Down to 4 of us left as far as I can tell. Really clear at the moment, 7 degrees, 73% humidity so everything is dripping already! Just scanned up and down the veil nebula with a lumicon oiii filter in the dob. Looks pretty dammed good! Orion is up in a couple of hours and that looks stunning in a dark sky. Pants weather for the most part, but glad I stayed for the week.

    Well, I got another clear night last night so added a few more subs to my NGC1333. My focus seemed to wander so it's not as tight as I'd like. I think the dark nebula is starting to show a little clearer but there is still far too little data to really pull it out without really going to town with the noise levels! It's clearer on the high resolution tiff image and seems to be less clear on this jpeg. 30s subs at -20C, 300 gain and 50 offset: 72 x L, 10 x R, 10 x G, 10 x B 45s subs at -20C, 300 gain and 0 offset: 90 x L, 7 x R, 10 x G, 10 x B Total L of 103.5 mins For comparison, here's the original: And here's the annotated version:

    Good night. Not quite crystal. Mainly went for loads of usual stuff. Mr fibble managed the horse head in his 1w" so we had a go in mine with his 2" H beta and got it o.k. Biggest problem was the constant battle with dew.

    I could answer 'all of the above' quite legitimately, but will offer an alternative. Mizar and Alcor. This was the first object I ever looked at through a scope, and it fascinated me after reading about it in a Patrick Moore book (something like 'observing the night sky with binoculars). The fact that it is a naked eye & binocular double, a telescopic double and that each of the components is apparently a spectroscopic double making six stars is something I find amazing. I rarely have a night observing without saying hello to it.

    all rubbed down and machine polished, feels harder than before. the mirror box inside the rocker box always sat slightly out of square to each other probably by 1 - 1.5mm, this done my head in and the dob mob had heard me mention it. this is now cured and sits perfect, so i can now sleep side bearings fitted, i used some 1mm thick fibre washers under each mounting point, because they squeaked sometimes, so hopefully cure that as well hope you dont mind me putting this in your section gina only kidding girl

    There have been several "runs" of Masuyama eyepieces going back to the 1980s or 90s if I remember correctly. They are made by the somewhat enigmatic Ohi Optical Manufacturing Co., Ltd of Japan which also makes a line of orthos branded by Kasai Trading, University Optics, Kokusai Kohki and others. Hence the similarity to EPs sold by these brands. Mr Masuyama was (or is) the founder of the Ohi Optical Manufacturing Co., although I believe the Masuyama eyepiece design was by his son. I've been able to try out earlier models, and they are superb although with a smaller 52 degree FOV. Top of the range (although I've never seen one) was a 4" barrel 100mm EP! I've no idea, however, whether the latest offering are equally as good. Presumably the design is significantly different to achieve the wider FOV.
