    It rained all morning and finally stopped sometime just after lunchtime yesterday. The clouds remained. I checked the satellite images and really couldn't see where the clear skies in the forecast were going to come from. Around 3pm, the clouds cleared and I put the dob outside to cool. I was really looking forward to Neptune's encounter with Mars. I finished up work around 4:45pm and was pleased to see Mars clearly in the sky. I popped a 9mm eyepiece in and was very pleased to immediately see the blue dot of Neptune next to the bright pale orange Mars. My eldest daughter came out and took a look too. I went for a 6mm ortho for 200x mag. The contrasting colours of the two planets made for some excellent views. I really enjoy planetary conjunctions and this was no exception. It was time for some tea and to get the kids inside. The session resumed around 8pm at my local dark site. It was club night for the Norwich Astronomical Society. The Milky Way looked great overhead and I was surprised that no one was out observing already. I wasted no time in unloading everything from the car and getting set up. As I was connecting up my dew heaters, I was joined by another member with binoculars. I talked about Mars and Neptune, which he wasn't aware of. I swung the dob round to Mars and we both took a look a look at the conjunction. The gap had widened but I still easily fit both in the same field of view. My first target after that was Comet 46P/Wirtanen. It was an easy find and could showed clearly be seen even in the 9x50 finder. A large nebulous patch with a bright core. My observing partner came over for a look too. It's been a good year for comets with this being my fifth of the year. I was now offered a view of Andromeda through binoculars by my fellow astronomer. It's really interesting to see the extent of the galaxy at low power. The show off in me decided to put the ES82 30mm eyepiece and point it at Andromeda too. The 2 degree field of view gives a spectacular view of Andromeda and its galactic buddies, M32 and M110. This was the first time of the evening that it crossed my mind that the transparency was looking really good. Next target was NGC 246, the Skull nebula. A fairly large planetary nebula which responded well to both the UHC and OIII filters I tried. I couldn't really discern a skull from it but there was plenty of nebulosity with several bright stars within it. The dob was now pointed at Pegasus, and the galaxy NGC 7331. The galaxy was a good size and bright. I used this as a starting point to try and observe Stephan's Quintet. Using SkySafari, I spent quite a bit of time establishing which were the stars that surrounded the quintet. I then experimented with various eyepieces. With the 9mm BGO, I started detecting a ghostly trio of galaxies. Very faint but definitely there. I was able to repeat this observation several times. Checking SkySafari after these observations, I decided that I'd seen 4 of the 5 galaxies. A fantastic result and further proving the excellent transparency. After spending a long time at the limits of what I could see, I decided to go for something brighter. M33 was bright even in the finder and clear as day in the eyepiece. It's bright nebula, NGC 604, was also an easy spot. I spent a little time with a UHC filter looking for bright patches that could be other nebula within the galaxy. With an OIII filter in place, I went to Orion to try and see the Flame nebula. A few maybe moments but it really wasn't happening. I was really disappointed by this. With conditions so good, it felt like this should be achievable. I moved down to M42. I normally observe this unfiltered and so the view through the OIII was quite stunning with the extra contrast of dark skies and filtering. Similarly the Rosette nebula put on a great show under dark skies. It was a really windy night and I was feeling the cold at this point. I took a look at NGC 2301, Hagred's dragon for something easy to see and fun. It's without doubt one of my favourite open clusters. Another member who was now out observing commented "There's not much moisture up there tonight". My scope was bone dry and I hadn't even turned my dew heaters on. I decided to take a walk around the site and eat some chocolate to warm up. On returning to my dob a few minutes later, I found that, other than one imager, I was now alone. I put my H-Beta filter and targeted the California nebula, NGC 1499. Once again the quality of the skies was confirmed. The nebula was an easy spot running left to right through the eyepiece. I was again using the ES82 30mm to maximise the field of view. It was amazing to see it so clearly when thinking back to the first time I saw it when it was very faint. I called the imager over for a look, he struggled a bit more but was able to see it. He then pointed to clouds gathering on the horizon and said "I don't t think we've got long left". Back to Orion and targeting, Altinak, I took the plunge to see what the ES82 30mm and Astronomik H-Beta could show me. First thing I noticed was that there was definitely nebulosity there. I started to moving slowly up from Altinak, as the bright star neared the edge of the field of view a notch in the nebulosity caught my eye. A moment of realisation hit me and a profound choice of words marked the occasion!! Surely it couldn't be? I moved back down and repeated the sweep, there is was again. With two stars sitting not far about it. I checked SkySafari. The stars were in the right place. I was seeing the Horse Head Nebula!!!! I went back down to Altinak, did a double take as there was the Flame nebula, clear as day. The nebula with its striking dark lane was obvious with the H-Beta when it had been invisible with the OIII. I kept on moving around picking the Horse Head up several more times. With the low magnification, it looked like a little black sock puppet against a hazy white background. I tried the APM HDC 20mm but that didn't seem to work as well. The large exit pupil of the ES82 30mm seemed to be the key. The clouds now reached Orion and it was gone. The whole drive home I just kept shaking my head in disbelief, I'd seen the Horse Head Nebula. The thing I couldn't get over was that it was a clear observation. I'd always expected it to be right on the edge of visible and leaving me with a question mark as to whether I'd really seen it or not. I thanked my lucky stars for a night under such great skies. I love this hobby!

    Finally found Wirtanen last after a couple of attempts. Could not resist a quick widefield snap with the "Nifty fifty" despite the gale that was blowing. It certainly is moving at a pace, I could see the difference in position through my 17x70's clearly within an hour. Looking forward to the next few weeks, especially showing my sister out visitor at the 1st available chance!

    Equipment in and out like a yoyo tonight. Windy conditions but managed to get 25 frames - 60s subs @ 1250 iso with a Nikon 800E on an Altair EDT-APO 115. This frame had a little visitor during the exposure so processed this separately in Lightroom 5.7 and PS CS3. I need to go through the other frames to see what remains from wind buffet.

    I used the 150PL, first of all without a Barlow. I did runs exposed for Neptune, then for Mars. This is exposed for Neptune: Overlaying one exposed for Mars on top of the over-exposed one works nicely: I then tried out my Revelation x3 ED barlow , first time imaging with it! I got Mars, Neptune and Uranus, all drizzled x3 as well. Mars, certainly a polar cap at 6:00, maybe a hint of darkness near Olympus Mons (I wish...): Neptune: Uranus: Afterwards I had a flash of inspiration and realised I could set up my dob and look through it as well! Clouds rolling in but I got to see a nice blue Neptune and a very bright Mars.

    Well it arrived today and I am smitten! ? However, at first I thought I had made a big mistake. The pallet box it arrived it was big - bigger than I expected and when I unloaded the pallet it looked even bigger... Once the children had been put to bed I started to set it up. It took me a while since I’ve never had a dob before. But eventually I got it completed. I checked the skies and they looked rather nice and clear, so I couldnt resist a quick try. Then I discovered I couldn’t fit it through the doorway of my study. I had to take it apart and transfer it in pieces to the kitchen where I built it again. Given it was a quick look and I’ve never collimated a scope before, I committed a cardinal sin and decided to just got for it with no collimation. I also didn’t both with trying the goto and just used it in manual mode which actually was rather nice. The scope movement was very smooth and it was nicely balanced. First off was with my 17mm es 92mm and straight to m42 - I immediately knew I had something special. I didnt use a filter and had my best ever ‘normal’ views of the nebulae. Lovely extension and the trapezium looked very nice despite the lack of collimation. So then I decided to switch to my night vision monoculars and Wow! I only went for 3 objects - m42, horsey/flame and rosette. M42 was wondrous - best views ever for me, nebulosity everywhere but also a mottling in the fish head area which I haven’t noticed before. Horsey was so clear, snout obvious and the extra image scale made it my fave view as well. The dark lanes in the flame were just so great. And then rosette just filled the fov with its wispiness. The wheelbarrow wheels are great since I can just wheel it out (if I can fit it through the door!). I’m very pleased that the scope just worked straight out of the box. (Although I do need to try out the goto sometime) Here it is in action.

    I can FINALLY say with 100% confidence that I was able to locate 46P/Wirtanen. The last few times I've tried with binoculars, I thought I had seen it, but wasn't absolutely sure. Last night, no doubt about it. I could see it with averted vision from my Bortle 5-6 front yard. I could also easily locate it with a small pair of binoculars. I looks very similar to a nebula or a galaxy. I also managed another first last night and got a couple of pictures of a comet. The first one is a single 13-second exposure at ISO3200 using my Canon 750D and an EF-S 18-55mm lens at 55mm. The second image is 10x10s exposures with the same camera, lens and focal length, stacked in DSS and processed in Photoshop. I didn't really feel like getting out my Skyguider Pro and messing with polar alignment so I could do longer exposures, but maybe I should have. Still, turned out pretty good and I'm happy that I can finally say I've seen it and have the image to prove it. Tell me it doesn't look like a smiley face winking at you!

    Nothing to go "Wow" about with my image, but just though I'd share my planetary image of Mars & Neptune taken tonight in the same FOV. I only just managed to capture Neptune at the top of the frame but got it nontheless. Glad to have some clear sky for a change and it's been a while imaging planets instead of attempting DSO's and failing miserably most of the time ?

    Hi all, It was around this time last year that I first started in Astrophotography and bought a Star Adventurer. Last night, after buying my HEQ5 Pro in September, I finally set about imaging with it for the first time, star alignment and setting the mount up sounding quite daunting, with the SA it was basically polar align, aim, and image. So things like time zone, long, lat, date, star alignment were a bit daunting and all alien to me. I had however polar aligned before and what really impressed me was how solid and smooth it was with the HEQ5 Pro - the adjustment bolts so smooth and precise and everything just so stable and smooth. Polar alignment was done quite swiftly, wasn't as accurate as it could have been but clouds had been forecast and I needed to get my head around everything - luckily I had already had help with what my co-ordinates should be thanks to a fellow SGL member some months ago, otherwise I'd have spent hours trying to work it out I'm sure! It was also my first time with a refractor, I recently bought my first - the William Optics ZenithStar 73 - and the build and finish is everything you read about them, absolutely superb. But what really amazed me more than anything was the focuser - coming from a telephoto lens to a telescope focuser is a monumental difference - the precision is amazing. I've never had a scope before so I can't compare the Z73's R&P focuser to anything else but it was absolutely solid in holding my DSLR, the markings on the draw tube indicated that the scope hadn't slipped whatsoever all night, but I don't see how it could either, it's just rock solid. A really nice feature of the Z73 is that you can rotate your imaging camera 360 degrees, so it makes framing a target really easy. The two star alignment wasn't without it's hiccups - for some reason the mount started slewing to the opposite side of the sky, so I checked a few setup settings, redid some, same thing, in the end I just switched the mount off, turned it back on and it slewed to the first star. Another great feature of the HEQ5 Pro I really like is the ability to then use the hand controller to center the star or DSO etc. After what was probably a not so perfect alignment I chose M45 to slew to - the mount slewed to it, just off slightly, so I centred it with the hand controller. That was pretty much it, made sure it was framed nicely, and began imaging. So here's my first image with my new rig. 1 hour and 45 minutes exposure time, 1m30 subs, bias, darks and flats. Processed in PS and Lightroom.

    Hello all. I had a crack at sharpcap steve. I took these two images on the wo 72mm megrez on the evo mount. With a asi294 mc. They were live stacked but not really got to grips properly with the stretching on the fly in that yet so I did a bit of post processing with gimp. The horse was 28 minutes worth of 30 second exposures. The rossete was a lot less but I cant remember for certain as it was a while back. I'm thinking I'm going to be doing both eaa and ap depending on the night ect. This is the second computer I've tried startools with now and neither have been enough to run it properly so it looks like I'll be sticking with gimp for now. There were no darks or lights added with these as I've only just figured that out. Next time though. Oh I used a 0.8 reducer too. Cheers.

    Looking through some 400 drawings , I found just a single shot at Taurus. I remember a "double double" and had another look at Σ7 with the closer Σ401 in wide field. Here's my old shot, a really beautiful sight. Just an hour to enjoy a few others. Σ427 (SAO 76071) showing lovely bright twins. Σ450, (SAO 76197) showing the tiny glow of the secondary. Phi : 52 Tauri ( SAO 76558) giving a ghostly speck of the secondary. Wasn't getting much joy out of the sky , turned to the double double and it wouldn't split . Both pairs were just bright blurs. Just dreadful seeing before clouds tumbled in. Other noted fine sights here, Σ422, yellow and blue. 30 Tau (SAO 93611), a wide triple here.59 Tau (SAO 76573) blue and gold.Σ559 (SAO 94002) spectacular twins. Don't forget the wide Aldebaran and Taggeta ( one of the eyeful of stars in the Pleiades.) Will return to Taurus under , Clear and better skies ! Nick.

    Respectfully, what you may fail to appreciate is that the magazine reviews in question are commissioned, subject to a set of given editorial guidelines, limited to a set number of words, aimed at a particular audience, and are time limited in duration. There is neither the magazine real estate or purchasing audience for the kind of reviews you are suggesting. Those type of in-depth and comparative discussions are much better suited to forum sections where the limited audience who may benefit from them can find them and the devilish details can be discussed at leisure, and where Earnest in Russia may well have room and time to expound or berate the qualities of some item based on his particular expertise and equipment available to do so. The First Light Reviews in the magazine in question are deliberately discursive in content, and introductory in nature, without getting bogged down in the minefield of personal opinions and manufacturer bias that so often blight discussions surrounding eyepieces, as often demonstrated on Cloudy Nights and a regular source of mirth to the more restrained European astronomy community. I hope that helps. Tim in England

    Hi Guys, I thought I would share with you my first DSO taken with my new Orion 8" Ritchey Chretien F8 Telescope. The frame is made up of 12 x 4min shots, no light or dark frames, using my Sony A7Rii camera. The camera had the long exposure noise reduction switched on, which does help to reduce the total number of stars captured by the camera, as the Sony A7Rii does tend to overdo the number of stars captured. The telescope was mounted on my trusty skywatcher NEQ6 mount and the guiding was via PHD 'of course' via my skywatcher ED50 guide scope. The shots were taken from my back garden in Stowmarket, Suffolk where I believe I am a Bortie 4 location, so the skies are mostly dark, with just a little light pollution from the main town, no filters used. My normal telescope is a Skywatcher ED100 Pro Esprit F5.5, which is an incredibly sharp scope, but with a wide 550mm field of view, great for capturing the whole of Andromeda but a struggle with smaller images like the Iris Nebula. I will say the Orion RC scope did need to be collimated out of the box, which was a little disappointing, and it was not just a little out of collimation, it was a long way out, but with the use of a collimating tool, I soon had it dialled in. First impressions of the Orion Ritchey Chretien 8" Telescope are fair, not super impressed, as it is nowhere near as sharp as my ED100 Esprit, but then this is to be expected based on price and telescope type, however, the pictures it has produced are pretty good, if you downscale the full 42MP from the Sony A7Rii camera, as can be seen in this picture. I purchased this 8" Orion Ritchey Chretien OTA mainly for Planetary work, but as yet I have not had a chance to 'get onto' a planet, fingers crossed some clear nights will arrive soon, so I can try. I welcome comments, many thanks Jamie

    I imaged the conjunction around 17.30hrs GMT with my Startravel and ASI120MC camera on the SLT mount (+fixed wood tripod). The image scale with my C8 would clearly have been too large. The image, processed in Registax6 from 200 frames, is shown below. The image is shown horizontally flipped to match the telescopic view with star diagonal. I puzzled for some time over what exactly I had captured, but the centre dot is Mars (overexposed) the faint dot at lower L is Neptune, and the brighter dot at upper R is the star 81 Aqr. I also took a run which has Mars only slightly overexposed, and looking very small, and inevitably not capturing Neptune.

    Finally managed to get some real flooring down today, in between dodging the showers. I completed a third quarter in the scope room, but forgot to take a picture. Tomorrow I'll hopefully complete the scope room and make a start on the warm room. For the gap around the pier, I will cover this with ply, leaving a narrow gap around the pier itself - all pretty standard stuff really. If I can find any varnish in my mess of a shed, I may give a quick coat to the underside of the ply to help resist rising moisture from the ground. I have to say, it feels absolutely fantastic to be able to walk around in the scope room (well, around half of it anyway) without falling down holes or balancing on joists. Although the floor level is only slightly above the height of the joists, it also feels different now that I'm able to stand, more or less, on the finished level and get a feel for the final height of the pier and the walls.

    I managed to get this rough colour image by combining the last 6 Red frames and the first 6 Blue frames, so that they could be combined without too much movement from Mars. Just 6 x 15 seconds for each of blue and red, 2x binned, synthetic Green using Noel's Actions. Not super quality, but it really captures Neptune's colour.

    Fabulous report Neil and congratulations for gaining the 'little black sock puppet', a fine description. Understandably your eyes would have become attuned after examining the California. It was blustery but transparency can be good in such circumstances. That dobsonian is really delivering as are your observing skills, the calibre of challenging targets gained, testament to that. The Flame is definitely an object that you determine through trial and error as to which eyepiece etc is most applicable for gaining optimum observation. It took myself a few observation attempts and taking regard to, such as Gerry's excellent descriptions, before I determined the best focal length for the scope I was using. Great result on Stephens Quintet, that comet and everything. I haven't got out for a while, only being clear when I have work the following day etc, so this report is a reminder as you say, why we love this hobby.

    I think Tim has very kindly explained the review system for the magazine in question both accurately and eloquently so there isn't much to add to his comment. I do rather tire of having to explain the way this works every now and again but here it is yet again for the record:- there is no need for scepticism when reading these reviews with regard to advertising revenue. The equipment reviewers, including me, are freelance writers and, for my part, I don't give a hoot whether the equipment I review is from a company that advertises in the magazine or not, I get paid to write the review by the magazine either way. If the equipment in question doesn't work well for me and is not of a suitable quality that the magazine's readership would enjoy using then it will receive a negative review and vice versa. The day the magazine ever pressurizes me to skew a review to reflect a poor piece of equipment in a better light because they fear upsetting an advertiser is the day that I walk, end of. Perhaps I could make this text a sticky somewhere. ?

    Tonight me and @Whistlin Bob went outside and did some astronomy Mars and Neptune which were in line with each other and our planet earth we observed them through the telescope as it was clouding over we then decided to look with our eyes we saw these: Cappella in the constellation of Auriga Hyades Pleiades We saw the Orion constellation and where the nebula would be but it was too small to see with the Naked Eye we could also see where the Horse head Nebula would be but wasn't there as it to was too small and too faint It has been a great night and I hope there are more nights like these Astronomy is just Amazing isn't it! we also set some imagery going as well and I am keen to know what we got in the morning hope some of your nights are as good as ours @EmuStardust

    Perhaps a bit of fun here, as it is not exactly an off-the-shelf scope (though Takahashi did sell 30 units in 2016 to coincide with the Mars opposition) but it is something that can be put together by using the 1.7x CQ module from the FS-60Q and the FC-76 DCU (split tube version). I was quite surprised by this as I thought the CQ module was specifically designed for the FS-60, but had I actually read the manual that comes with the FC-76 objective unit, I would have discovered this was possible long ago. But now during 2018, I have spent quite a bit of time and aggregated my thoughts into a review which is on the link. http://alpha-lyrae.co.uk/2018/12/07/takahashi-fc-76q-review/ Feedback always appreciated.

    Hi all, This evening I intended capturing some RGB images of the Mars/Neptune encounter, but I hadn't bargained on the buffeting winds and the sheer speed of Mars's movement. The result was that it wasn't possible to align the RGB channels. However, I managed to create this rather neat animation. 6 x 30 second exposures, 5 minutes apart. Atik 428ex, 200mm f/5 Newtonian. Triton showing up well. It was a splendid sight! Here is a stack of 5 x 30 second exposures. For once, I quite like the dramatic effects of the diffraction spikes and other optical effects.

    Don't judge too harshly, as this is the first long exposure image I've taken since acquiring the new kit a couple of months ago, and even though it didn't go according to plan, it does show an incremental progress I was counting on. I got the new DSLR shutter release remote activated for the first time, removed noise reduction selection from the DSLR, and was hoping for several hours of data. What I did get was 16x180s decent lights out of 32 taken before the laptop, hence the guider, shut down on me, and having forgotten to charge the backup batttery (so many things to keep in mind for a newby!), my night was done without even getting any dark images, bias or lights. Half my images were useless from star trails, probably from a jostling of the tripod that I thought was not as serious as it seemed to turn out, and even this image shows signs of it. So this is 16 stacked images of 3 minutes each, with 30s between exposures (is this enough time between exposures?) with no help other than some adjustment in DeepSkyStacker to acquire some contrast, with some false blue added in a totally inadequate microsft photo editor, because my wife won't let me get Adobe Photoshop CC until Christmas! I opened my first album, called Beginnings, and this is the first entry, but I thought you might like some proof that your advice has not fallen on deaf ears, though I realize I have a LONG way to go.

    OK, enough hijacking of the thread and back to the OP's original question. I used my set for three weeks or so when the weather would allow and I rather liked them. I have no idea whether the stated AFOV's are accurate or not so if this is important to you, you should indeed research the issue further. Looking at the notes I made during my review period, my own observations showed the following dislikes:- The dust caps for the eye lens are tapered making them a real pain in the neck to pick up - I found this very frustrating! Even with the rubber eye-cups folded up, eye placement was rather too critical until I had been using them for some time It was only with close scrutiny that I was able to see the whole field of view and this was without spectacles The field stop was not particularly distinct which was rather a shame The 2” undercuts were a good match for my compression rings (William Optics 2" dielectric star diagonal with 1.25" adaptor) but those on the 1.25” versions were far too narrow to be of any use so they were superfluous Having two different barrel sizes is a pain - I much prefer the 'double barrel' design of my Hyperions for quicker eyepiece swapping @rwilkeyI have always enjoyed reading your own appraisals of various eyepieces on your excellent website so I will be interested to hear how you get on with your 15mm and 21mm versions.

    Wow! That is so awesome; and you can see the blue hue of Neptune and the phase of Mars so clearly! Reggie

    On the subject of Sky Orientation, When I first began using telescopes I thought upside down and reversed imagry was a flaw in the observing ointment so to speak because naked eye when looking up and to the south every thing is right side up but when I turn round 180° and look up and north everything is upside down so then this adds another element to the already confusing upside down images coming through the scope and then if I use the erecting eyepiece to the south the imagry would then be upside right as I see it naked eye but now useing the erecting eyepiece looking north the image in the north looks upside down...It was at this point I realized that my naked eye view of the sky was what matters and scope image orientation is of little concern because with the cardinal points and no horizon to hold relative upside down or reversed means little once you have a mental map of the sky...yes this is confusing but one does get used to all this quite quickly and all of us have had to overcome this truth to succeed. As well as objects and constellations move around Polaris along the celestial plane as they rise in the east and they move across the sky they appear to rotate as they move around ones relative position to the nearest pole, this is more pronounced nearer the celestial pole in ones particular hemisphere weather it be north or south and less pronounced at the celestial equator...so in reality there is so much going on an erecting eyepiece cannot even begin to compensate and is better left for terrestial observation or as to say "its intended use". Best of Luck, Freddie ?

    Guilty as charged , we are human after all and what constitutes "the greatest contribution" is a human concern, so guilty as charged. I don't see anything wrong an anthropomorphic view in this respect, I'd go further and say it is built into the question. Jim

    Hmm? Quadroscope hey. Sounds like one for the imagers, R, G, B, and Lum all at once.

    I am fairly certain that the Sky at Night reviewer knows what he is talking about.
