  1. Hi everyone, It looks like most of the UK got some clear skies this weekend, even though it was around a full moon I was still glad to get out and at least have a go! - I hope you all got the chance to get out too It gave me the opportunity to try and make a video also which I've been enjoying doing recently I imaged for two full nights, dusk til' dawn, and in the end captured 104x2m subs on M42, and 300x2m subs on M51. - very tiring! I'd made a mistake on night 1 and accidentally recorded that night's data all at 300 gain! - I noticed on night 2 and put it

  3. 6.20pm Saturday – clear, still, mild – Betelgeuse appeared in the south – big 127 Frac used. (Full Moon very low, east, behind houses.) 32 Ori – 4th & 5th mag, 1.4” separation – reached via Bellatrix – x33, 100, 200, 240 – got the split – close but clear in moments of good seeing – rings around primary, secondary a little dimmer, at 1 o’clock. 33 Ori – 5th & 6th mag, 1.9” – just aimed between Betelgeuse and Mintaka – slightly brighter in a faint field – x33, 100, 179 – very clear split, similar brightness, sec again at 1 o’clock. Eta/28 Ori – 3rd & 4th mag, 1.8” – i

  4. This is the first observing report I have done here, so hopefully it's ok! So, for quite a while now I have been focusing on astrophotography. With the full moon tonight, I decided instead of setting up the AP rig, I didn't want to waste the clear night so for the first time in ages, I got the 150p on the EQ3-2 out for a visual session. Yeah, it's not the best scope, and I only have the BST starguider eyepieces, so quite a modest setup, but it'll do! I started by going for a red star I heard about not long ago and cannot believe I never heard of it earlier. La Superba in the constell

  5. Shot in Ha over the last 2 nights (just over 2 hours of integration time). I messed the framing up, hence the weird cropping, but overall I'm really pleased with this. A freak occurrence may be on the cards tonight too, with a THIRD clear night on the trot !! If so, I'll start grabbing the colour data.

  7. I'm very happy to say that last night (27 Feb) I finally managed to see the Pup! I'm so thrilled by it I spent nearly 2 hours observing from 7:30 to 9:30pm and managed to see it both with or without diagonal and with both 10mm and 6mm eyepieces giving 270x and 450x respectively. As other have said the position of the Pup is at 4o'clock without diagonal (Dob view) and at 2 o'clock with a diagonal (refractor or Mak view). At these magnifications the separation is not the issue but the glare from the main star. I came to realize that my EP have too much light scatter around Sirius A

  8. I have assembled this deep sky set up mostly over the last few cloudy weeks and have been testing it over the last couple of nights. This is actually my first DSO image, well...apart form a few pics I got with a 700D on a star adventurer and wide field lenses on my hols in Tasmania a few years ago. Let's say its my first DSO using a scope! SW 200/1200 dob OTA, EQ6, Atik 383L+ mono, ZWO efw 8x1.25", ZWO OAG. Melotte 15 - 24x600s Ha bin2x2 (Baader 7nm).

  10. I decided to have a bit of fun and make a time lapse last night whilst imaging the rosette nebula on my telescope. The time lapse is composed of 317 x 4s exposures (2 exposures per minute over about 2 and half hours) at f3.5, ISO800, taken with the Canon 2000D with stock lens at 18mm. Video made at about 25fps. Orion Timelapse.mp4 Image of the rosette to hopefully follow soon - depending on how images from the last couple nights turn out as the moon has been out. Just need to get images through the blue filter tonight. Adam

  11. A handle for the TecnoSky 125. Now the handle “borrowed” from Big Red can go back. It’s actually a “motorcycle handlebar adjustable balance bar” but just happens to make a great telescope handle. And being intended for use on a motorcycle it’s solidly made. It is a bit long but just fits with a StellaMira Losmandy plate. It can be extended much longer by loosening some grub screws and pulling out the end sections but not needed for a telescope. Just blotted out the brand name with a permanent marker and will leave that on the bottom anyway. And under 10 quid if you don’t mind waiti

  12. Not been out for quite some time but grabbed this last night . Looks quite funky but the cream colour of the white mount is from a bit of tungsten lighting indoors, the red and blue bits are from the volt and amp readings on the power bank .

  13. I've just been having a quick amble around the double stars in Orion now that my ED120 refractor has cooled down. The seeing seems to be absolutely top notch here currently Text book high power star images. A real pleasure to observe Rigel, Alnitak, E & F Trapezium, etc, etc. Really clean split of 52 Orionis at 360x !!!! - 2.5mm setting with the 2mm-4mm Nagler zoom. Steady as well - wafer thin dark thread between the airy disks. Dawes limit for the scope is .97 arc second and I believe 52 Orionis is around 1 arc second in separation so no complaints at all here

  14. Yesterday was an unexpected clear(ish) night, so despite a full moon, occasional scudding hazy clouds, and later increasing haze and fog, I set up my latest wide-field imaging rig, consisting on my ASI183MM-Pro, combined with my Sigma 50-100 mm F/1.8 zoom, with a ZWO 5 position EFW, equipped with a Baader L filter, and three Baader F/2 narrow-band filters (H-alpha, O-III, and S-II), all on the old EQ3-2, tracked, not guided. I managed to get 30 120 s Subs in H-alpha and O-III, but only 9 in S-II, when fog scuppered any further attempts. I captured flats and dark flats in all three bands separa

  15. So I set out with a varied target list, based around coloured doubles, a couple of solar system ideas & lots of recommendations from fine SGL-ers. Still have a few to chase down but three good sessions since Thursday, random notes below.... 25.2 - 8-9.30pm ST80, BH Zoom, Steady seeing. 97% moon transparency: occasional high milkiness. N. Aligned Sirius Aldebaran Goto Mars, accurate - nice gibbous disc but tiny. Goto Uranus - probably, faint, greenish, maybe - not a point, not a disc. M45 - bit disappointed then realised I still had the Barlow on from Mars/U

  16. Here's a challenge from Nigel Longshaw in Feb's AN. Id noted it in my diary as something to look for if it was clear tonight - and it looks like it might be. I didnt know about it before I read Nigel's article. Hopefully others may find it of interest too.

  17. Seen a few questions on this so thought as I managed to get mine delivered a few weeks ago I would write something up. I managed to nab a couple of clear nights this week to try the filter I ordered back in January from Flo (which came with the normal spell of miserable weather). I needed a target and as I hadn't managed to get anything on it this season I went for M42, now this may not seem like much of a test but I was up against the following B6 skies (at the best of times) Almost full moon (no head torch needed to read a book) Target low on the horizon over th

  18. I've been observing the moon tonight, like many of us I expect. The craters Messier and Messier A, with the distinctive comet-type rays extending from the latter, are nicely on show in the Mare Fecunditatis and will be for the next couple of days, clouds allowing. Well worth a look though any telescope. While finding out more about this interesting pair of craters I came across this fascinating photo in the Internet Archive. It shows the Apollo 16 Lunar Module "Orion" in lunar orbit while it is being inspected from the Command Service Module "Casper", the photo being taken from the l

  19. After a 20 year long hiatus - my last astrophoto was captured with a film camera in 1997 - at the beginning of 2020 I decided it was time to start again. So, January 25th 2020 I brought home my used Sky-Watcher NEQ6 Pro and I immediately started taking photos. Obviously, my first target was M42 in Orion. This was my first digital astrophotography. 31 subframes, 30s each, taken at ISO800 with my unmodified Nikon D90, Nikkor 70-300mm at 300mm f/6.3 - January 28th, 2020, home front yard, Bortle 5/6 sky, no guiding, no filters. A grand total of 15.5 minutes... A couple of week

  20. The very high end refractors have always been there. The outstandingly good budget ones, now plentiful, have not. This is the age of the affordable telescope so let's not get hung up on how expensive the high end stuff is. The real story is about how good the cheap stuff now is. And if you're short of cash, why go for a refractor in the first place? There are insanely good budget Newts available these days and blessèd be John Dobson for showing us how to mount them. The Apos and semi-apos debate is a bit of a red herring since 1) the difference is very slight, 2) the individual scope

  22. Hey Everyone So last night i attempted Orion Nebula for the first time. Probably on the worst night because of the moon It was a last minute decision so it was on a static tripod. Canon 6d, Samyang 135mm stopped down to f2.8, iso 3600, 350 x 2sec subs. This is just a quick processing this morning but I'm quite chuffed especially with the moon being so bright. Needs more work though.

  27. Whilst waiting for clear weather, I decided to reuse some data that was previously acquired by my Skywatcher ED80 and my Esprit 150. I used the Esprit data to get maximum detail on M106 and its companion NGC4248, whilst I reprocessed the ED 80 data such that the resultant background showed very faint objects. The ED 80 data is LRGB whilst the Esprit data also contains a Ha blend into the red channel. On the processing side, I used RegiStar to align the Esprit 150 and ED 80 images and then used Pixinsight's Gradient Mosaic Merge to create a seamless image. Alan M106

  28. I was trying out my modified Quattro with 5x powermate last night but difficult to get much detail with the moon being pretty much 100% full. This was the only image worth keeping TBH, but I blowed if I can figure out where it is. This rig is a bit unusual - I use the camera at prime focus with no secondary - which means I think it has one less plane of reflection than a regular Newt. Maybe not. This region ought to be South West - but I can't see it on any atlas. Grateful for any thoughts! Edit: Byrgius maybe? Quattro 250 with Powermate x5 and Omegon 385C. Captured with Toupsky

  30. I cannot believe I found this in a cat charity shop for 1 euro! Signed by the author as a bonus. My only other signed book is an Andy McNab I bought at Southampton airport. I have long been a fan of Andrew Chaikin, ‘A Man on the Moon‘ and James Scheffer ‘The Race’. Moondust seems to complete the picture. I particularly like the way the story is told from the point of view of an English child who grew up in the States. Like both sides of a view point at the same time. I enjoyed it that much I feel guilty about it costing so little, so I made a donation of goods to the charity shop it

  33. I thought I'd try out the Asiair's Video function with my new Asi2600 on the 60mm little Tak . This is the best 25% of a 2 min 40 video. The Asiair seems to only use the central part of the cameras sensor so I could only just about get the full moon in the FOV in video mode but it seems to have worked quite well. Hope you like it, thanks for looking.

  35. Hi all, I hope everyone is well. I am relatively new to the astrophotography side of things albeit I have been dabbing into it on and off for about a year my DSLR (400d - so not the best). In recent times however I treated myself to a dedicated AS camera in the form of the 533MC Pro. Post processing however is new to me albeit I do/can use Photoshop. Last night I had a go at capturing The Orion Nebula and the Horsehead Nebula as they happened to be in a good line of sight. I started off with a fairly modest 10 x 60 second lights, 20 darks, 20 flats and 60 bias at 0.01 sec. C

So, last night I had a lot of firsts .. my first sight at the Double cluster , the dragon fly cluster and the starfish cluster .. my favourite the Beehive and Plaides were also on my list . a lovely 97 % lit moon , but my best last night was the spiral star cluster .. all this with my evostar 120 on an AZ5 mount . Of course no night can be complete this time of year without looking at Orion and the wonderful , Sirius . I didn’t use much magnification.. mainly because of my target area being wide field .. I did have cause to try a zoom EP , which I was very underwhelmed with . So I put my litt

  37. My dslr set up in my flats communal area earlier this evening before the moon rose. Trying a new settings procedure with my Omegon lx2 mini track & Canon 450d unmodded, took 28 subs at 1600 iso 3.5f 1min before the moon started to wash out the sky and make the subs to bright but achieved a good histogram about 1/4 to the right. So hopefully with the moon rising later moro and hopefully clear skies I'll try more subs again at these settings or 800iso. Took the binos out with me whilst the dslr was clicking away, saw pleiades, beehive cluster, M35 with averted vision and think a hint of M31

  38. The California Nebula and Rosette Nebula in H-alpha taken over the last two nights with William Optics Zenithstar 61 and modified Canon EOS 100D. I used an Optolong L-eNhance filter then processed the red channel only. I’ve only recently got a modified DSLR and it’s my first time shooting in H-alpha so I’m really amazed at how much contrast there is in a single frame and the fact that there are no gradients to deal with when processing. Also, being able to image even when there is a full moon is great! And the Star Adventurer did a brilliant job to handle 5 minute exposures at this focal lengt

  39. Captured with the Skymax 102 & Nikon D7000. 25% of 250 still frames aligned in Pipp, stacked with AS!3. Deconvolution with IMPPG. Original image, then one with linear contrast added in PS, and another with more contrast again. This feels like a decent image to me, now I feel like I'm getting back into the Lunar imaging properly after a fairly long break. Click through to full size. Original Linear Contrast More contrast Then a little bit of fun. Annotated view Pseudo aerial view of the terminator.

  40. I'm sure you're all aware of the full moon at the moment. I went out last night with 100ED refractor and the moon was high in the East and extremely bright. So double stars were the target. I did consider some open clusters but I had tried a couple the night before and even they weren't at their best in the glare of the moon. So doubles it was. I've started just using my zoom ep for doubles, with the occasional Vixen 4mm for closer separations but the zoom saves a lot of ep changes and fov isn't really a consideration for double stars. I started with HD5005 in Cassiopeia which is actually

Hi everyone Sahara dust and a full moon with which it could be illuminated, so not the most ideal conditions and with EKOS' sky parameter near on 30, maybe time to do some terrestrial moonlit stuff? But no. With a fast 208mm f3.9, and as far away from the moon as reasonable but still below the celestial equator, the fits histogram was central at 90s. We managed around an hour of them, never expecting to get anything like. Hats off to StarTools for rescuing something from the gradient. Thanks for looking. Anyone else? 700d on ES pn208. ISO800

  43. I was out observing from 8.30pm to 9.50pm and again from 11.45pm to 00.30am. I had a break to wait for a little more of M Orientale to become illuminated. Many people have problems observing M Orientale because it is difficult to know what you are looking at, unless you are very familiar with the area. Of course, it also requires a large and exceptional libration to the S/SW. The best chart I have seen is section 68 of the Cambridge Photographic Moon Atlas, published in 2012. Alas this was a short print run and it is very hard to find. If you have one, hang on to it, you want bel

Started out playing around finding the Messier clusters in Auriga, then the Eskimo. Had a real battle to see anything of M51 but thoroughly enjoyed that challenge. After that I decided it was time for the Moon. Used the Nag zoom then switched to the Vixen HR 3.4mm as the seeing looked good. Really lovely crisp views. I’d forgotten how good this little scope is. It was only when I went inside for another eyepiece that I even realised it w

  47. had a little play with new scope and cameras this evening- getting to grips with the very basics. It was quite hazy but not too cold which was nice. Good news is Sharpcap polar alignment is pretty great- its easy and seems to work! And the Bahtinov mask is a genius thing! It works too I synchronised the focus of the main camera with the asi120 on the oag so i can use the little Asi which has a much faster frame rate to focus them both- seems to work quite well. Mark

  48. Interesting views of the Mare Orientale area tonight compared with last night. It's fully illuminated to the limb tonight. The full length of the darker Lacus Veris can be seen whereas I could only see a small part of it last night. I think I can just make out the crater Kopff very close to the limb just as a highly elongated darker sliver of tone. On the opposite limb, the Mare Crisium is showing well with the "cape" of the Promontorium Agarum extending across the mare on the western side nicely illuminated. My other half is watching old "Star Trek" episodes at the moment so

The "Pup" star was not consistently visible but was positively there during periods of the steadiest seeing. I was motivated to sketch the view with the 3.5mm Pentax XW eyepiece at 257x (refractor plus mirror diagonal view):
