  1. Well it was clear from midnight above us in York last night and it was the first chance to have a proper look around with the 8inch dob. Went outside, copy of turn left in hand with all intent and purpose to find somethings for us as beginners to view. I never picked the book up again last night. Started at Orion Nebula and after viewing that just spent the next two hours just looking around in amazement at the night sky through the scope. with 26mm eyepiece in all night I just kept staring at the night sky. I know and slightly regret I didn’t focus my energy in finding objects to

  2. Hi! This is my first post here in a place besides "Lunar Imaging" lol I am somewhat of an odd duck in our hobby I think. I arrived to it via photography, and a chance shot at the moon I was amazed by with my DSLR gear about 5 years ago now. Ever pursuing better results, I dove into astro gear a couple years ago... scopes, mount and planetary cams. But... because I am somewhat lazy, and very busy with family and work.... and very light polluted in my neighborhood, I just never pointed my scopes anywhere but the moon - and planets now and then. Till now. This past week, I took d

  3. Hi everyone, My first post here - thought I'd join up and hope you might enjoy seeing the odd Southern hemisphere target. In 1969 Rufus Thomas wrote - "You flap your arms and your feet start kicking Then you know you doin' the funky chicken". Which is possibly what the guys at the AAO were doing when they named the 'Running Chicken' nebula! I've presented NB versions of this timeless classic target here with and without stars. 6 Hrs HA x 900 sec 2 Hrs O3 x 900 sec 3 Hrs S2 x 900 Sec Taken via Stellarmate (while sleeping!) from my light polluted Bortle 6 suburban B

  4. Hi all, yes many good versions here and I am working on mine. To get a break I now entertained myself by downloading 10 versions posted here (which I subjectively thought looked rather good - no names mentioned), and then made a composite where every version was weighed in as 10%. So this is what the average M33 looks like right now. Obviously this posting is outside the competition! Cheers, Göran

  5. Tonight was the big night. My first outing with a telescope! I planned to observe originally from about 7-8pm although unforseen cloudy skies delayed my outing in the back garden until 12am! When I finally got out I had have my first crack at doing the two star alignment. After a few minutes of nervously trying to pick out an easy start to get to I went with Regulus. It was my first time viewing a star in a telescope and I don't think I'll ever forget it. I then selected arcturus as my second star, the scope slewed over to it and it was pretty much bang on in the middle of the eye piece.

  6. I've joined the club, and tonight was the first chance to use the SW Startravel 80 in anger. Clear Outside had been promising clear skies all day and at 11pm the clouds vanished and I saw stars for the first time in weeks! I had the new scope and the dob out cooling for an hour already. Firstly, a star test on Polaris. Hmm - very odd shaped stars. Having watched Astro-Biscuit's latest video, I recognised pinched optics and tried to loosen the lens cell. Jammed tight! I had fiddled with it earlier in the week, when I had heard the lenses moving when I tilted the scope - tightening the plas

  7. I fully appreciate I am amongst some amazing solar imagers here, but here goes. Whilst clearing out the shed Saturday 13th March I set up my old 3” frac and did some solar projection and managed to see a sun spot, ignore all the marks on the old plate, it was definitely there. Can anyone confirm.

  11. 6th magnitude open cluster NGC 1746 in Taurus contains two other classified open clusters, NGCs 1750 and 1758, but it would appear that 1746 is the dominant. Quite large at about 50 arc-minutes. I could have gone for a close up, and may yet, but there is a fainter open cluster nearby, NGC 1802, this is to the far centre left of the image, so to get both in the frame I used my 420 mm focal length TSquad refractor. As can be seen, both the clusters are quite loose. Data obtained over two nights, 11th and 13th March. The target was well towards the West limiting my imaging time and passing clouds

  15. First night last night with the AZ GTI setup properly in EQ mode. What a difference!! Must be something wrong with my alt axis. In az/alt mode i couldn't even get 10 second explosures - big jerks randomly, etc - and I'd taken it apart and rebuilt it with no improvement. Now getting 30 seconds easy - didn't try and longer but hopefully can. 100 subs with no duds is a first for me. Yes, these are terrible compared to the amazing pics on here, but it's a steep hill! Canon 1200d modified, with a 300mm F4 L on the AZ GTI EQ mode. First time I've manage to get any of the nebulosi

  17. Hi my fellow stargazers! After enduring a torrid two and a half weeks of overcast skies, finally got a nice clear sky last night. Giddy with anticipation, I brought out my 10 inch dob into my backyard to undertake some much needed observations. I decided this session was exclusively for studying the constellations Leo and Centaurus. Here's what I found: Leo Algieba: A mesmerising sight! Love the colour of this double Leo Triple: NGC 3628, M65 and M66 all seen in the same field of view at 70x. Wow, my first time observing the Leo Triple galaxies, fell in love with this group. I

  20. In the last 3 month, there were few nights with good conditions for under arcsec double stars. Meanwhile I bought a 3.2mm Skywatcher planetary EP for double stars and I am impressed with it`s performance. As the 2.5mm TMB, it need good seeing conditions. This is the list of the under arcsecond doubles observed in the last three month, made with my two dobsonian telescopes.

  21. As the chap on the video says, it is obvious which way round the thicker lens goes , but the front element , not so easy to distinguish once you've been turning it over to clean with the baader magical stuff ... what happens if you foolishly put it in the wrong way round ? Ahem, not telling how I know this, but what you see is a circular halo around any bright point of light (like a streetlamp which is all you can see due to 100% cloud cover) , a solid circle of light like the ones around saint's heads in medieval paintings . Should have borrowed your sharpie arrow strategy ! Fortun

  22. Couldn’t find any of the black EQ6 pillar extensions in stock so ordered one of the white ones and made it into a black one. Ground off the powder coat on the tube and primed it with acid etch primer. The top plate was flatted with sandpaper and primed with a barrier / sealer primer. Then sprayed both with 2 pack satin black paint. The 2 pack paint is a tough as powder coat when fully hardened but expensive. Now the Tecnosky 125 can be pointed at the zenith without fouling the tripod legs.

  23. Having purchased a AF2 focusser around Oct 2018 the service received then was exemplary. On arrival all was good but after about a month the usb port on the focusser detached from the control board. No problems. This was replaced without question and within the week I was up and running again. Now 2.5 years later following some issues with my AF2 DeepSkyDad provided a free upgrade to AF3 that addresses the issues I have been having. This upgrade arrived and within the week I was up and running again. Awesome service all round. Thank you.

  28. Heya, AR2808 is an interesting region, in HA it has a nice extensive plage and has filaments between the poles, but in the photosphere it's a tiny pore with not much else to see. Mean while, a smaller region that is now AR809 emerged and has a much smaller HA representation with a tiny plage and the poles are close together, yet in the photosphere it has a much bigger spot that is developing rapidly this morning (maybe it will grow larger and the poles separate a bit more to become a bigger region). It's a really great representation of the difference between the chromosphere and photospher

  29. Here's a wide view of the IFN around M81 & M82. Can just make out Arp's loop and Holmberg XI. Taken with the Samyang 135mm f2 and Canon 6d, about 3 hours of data in 2 minute subs on the Star Adventurer. (Flats and dark bias, no darks.) Had to crop it down a bit as the framing wasn't great, I was literally shooting in the dark on this one. Wish I'd moved over to the right more to catch more of the brighter nebulosity, but I didn't really know what to expect until I stacked it. The inverted BW version shows the extent of the IFN a little more clearly. Fi

  30. Hi guys, I made a quick video tutorial to try and show an easy to follow method to take your OSC narrowband data taken with filters such as the l-extreme and other similar ones and turn it into a hubble-esque palette. I know that there's lots of ways people like to perform this sort of task, but this is how I've self-taught and I thought if I can do it then anyone can! This tutorial uses PixInsight, the EZ-processing suite, available free here https://darkarchon.internet-box.ch:8443/ and also finally requires that you have Starnet installed and working in PixInsight, though I

I was totally focused in the other thread on the galaxy itself and did not even think about what else might have been caught. Interesting to see we picked up the same quasars and I had no idea there were PGC galaxies shining through 3726 (on the right hand side) Mike

  35. I think your less is more strategy is spot on. I find that I get more enjoyment from the simple pleasure of looking at just one or two objects for the whole evening. In terms of Stellarium, I find the ocular view invaluable in locating difficult objects.

  36. Thanks all. The scope is fairly new. Only used a few times before I received it and the focuser actually feels spot-on. I bought it with the intention of fettling, so no concerns there. Considering the pinched optics (my fault), it won't surprise me if it's just a case of shoogling the lenses to sort out the collimation.

  41. I want to share the nice observing session I had last night. I was out from 8pm to 10pm. After the showers the sky cleared and the transparency became almost unreal. I went out after dinner and was very excited to be able to spot the Beehive and the Double cluster with naked eyes from my SQM 20 location. It was still windy so not a night for high mags. I decided to focus on open clusters and DSO and mounted my 6 Inch Newt (The £100 C6N which was a real bargain from @FLO while it was available). I am using EQ5 in manual mode with a tiny 6x30 finder so a big part of the enjoyment is the '

  43. Nice report ! One trick that can help the star image quality with these scopes can be done indoors in daylight. Point the scope upwards and keep it that way though this process. Remove the lens cap and dew shield. Loosen the lens retaining ring a couple of turns so that the lens elements are loose. Gently "slap" the objective cell all around it's sides. This gives the lens elements a chance to settle into their positions. Then very gently tighten the lens retaining ring again just enough to hold them in position. If the comatic stars continue to be an issue, you will need to think ab

  44. For visual observing I greatly prefer an alt-az mount to a German Equatorial. The Equatorial needs polar aligning and balancing and the necessary counterweights almost double the weight of the whole payload. Then, in use, the scope changes position radically between objects, the eyepiece ends up at odd angles and needs rotating, and the sky is divided into two halves requiring a meridian flip. What a palaver, even when permanently mounted! So I have always enjoyed my fork-mounted alt-az SCTs for their ease and comfort of use and fast setup. I've previously had 8 and 10 inch and now have a 14 i

  45. Hello there, I recently got my hands on an old canon T1i + kit lens and decided to make some tests with landscape astrophotography, more for the sake of learning how to operate the camera than anything else. I live on top of a small hill from where I can see a good part of the (small) city where I live, and at this time of the year the Milky Way shows up from the other side of it, rising at an angle of almost 90 degrees with respect to the horizon. So here is the thing: I thought it would be really nice if I could get a picture which shows some structures and details of the Milk

  47. I bought the Logitech C270 webcam to dip my toe into astrophotography, as I'd heard good things and it is usually a straight-forward mod. A known risk was that sometimes the lens mount is M8, not M12. And the M8 is what I received! Knowing others have faced this issue too I decided to CAD and print a solution. The files are attached here, or you can obtain them from thingiverse https://www.thingiverse.com/thing:4792840 It would be better to mount to the board, and I am thinking of doing a new design which will replace the lens mount itself, but for now this seems to work well - the l

  49. I'd be tempted to say my OVNI-M night vision device as it's totally transformed my stargazing. However, the accessory that I always use, whatever the telescope, is an adjustable height observing chair. Not only do I find it more comfortable, but I actually see more, especially on difficult threshold objects. I have two such chairs, firstly a Skywatcher Anti-Tip /Omegon Astro Observation chair I use with my Dobs. Secondly, a Ksera Telescoping Folding Stool for my refractor. This is exceptionally light and compact and also perfect for travelling. Costs less than £30. Go to

  50. I'd very much recommend a zoom eyepiece as your workhorse. One zoom eyepiece will cover multiple focal lengths and so is really excellent value for money. I have both the Svbony 7-21mm at around £45 plus the Baader 8-24mm at £189. The Baader is better, but not 4x better. Despite having high quality fixed focal length eyepieces, I use a zoom a lot more often. The zoom plus a Barlow lens and a low power, wide field eyepiece is often all I use the whole evening. Your existing 25mm eyepiece will fulfil the low power role to begin with. Fixed focal length eyepieces may be slightly b
