  2. M78.......... Stand back.....don't look at this one too closely. This is somewhat over processed - but it was necessary because of very 'noisy' data.....my fault once again for imaging in very high relative humidity (> 90%). Imaging telescopes or lenses: Takahashi FSQ130ED Imaging cameras: QSI 6120i Focal Extender / Reducer: Tak QE 0.73x Astrodon Lum: 60x120" Astrodon RGB: 3x20x120" Integration: 4 Hours

  4. I recently wrote to my local council concerning the light pollution from the numerous street lamps around my house and received a written reply today from the council leader which stated.... “Officers fitted shields to the street lights in this location to alleviate this problem in July 2020. We will re-assess and fit either an additional or alternative shield following identification and procurement of a suitable product. We will also be fitting an alternative lantern which may reduce light nuisance further”. so glad I did this and would say it’s definitely worth contacting the coun

  9. Quite recently I sold my narrowband filters for my OSC camera to fund an upgrade and because I'm only left with the broadband light pollution filter, I felt like shooting a galaxy, but I when I was zooming through stellarium I thought that a galaxy and a planetary nebula in the same photo would be nicer so I stopped to M97 - M108. This is a crop from the wider field of view photo. I drizzeled the stack x2 and cropped it to match the fov of my ASI294MM on the AT106 in case I will add some luminance to it at a later date. I annotated it in pixinsight to show the little fuzzies in the photo

  11. Hi all Some may have seen my previous post (M13 & M104), and I have received a couple more images back through from the OU CoAST Telescope in Tenerife. These are again just single 3 minute exposures of M51 and M101, taken last night. No real editing again apart from some level tweaks in PS! I am going to start pulling data on just M101, and attempt some stacking to pull out more detail. Obviously, all I have done here is request the target via a web portal, set the exposure and filter types etc and pressed send! The telescope did the rest! No skill like the rest of you guys, but

  13. After humming and hawing for years, I finally pulled the trigger on a 35mm lens for my old astro modified Canon 600D. I wanted something portable for 'grab and go' widefield full constellation and MW shots. My 600D has barely been used in the past 5 years since I moved over to mono CCD imaging, in fact I sold the camera a few years ago, then bought it back a year later and still have not been using it. The lens I purchased was 2nd hand off mpb.com, and is the EF F2 35mm IS USM. It arrived in excellent condition as advertised. I had a couple of hours clear sky last night between 11pm and 1

  14. It has been very grim here the past 10 days and looking likely to be for another week or two. So some binoculars to try and see some local wildlife or at the least check who has left their bins out. Have been working from home nigh on a year so need some excitement. A reconditioned Asiair from Flo. I know one is available in the for sale section - at an excellent price and to charity too however i'm delving into the unknown and feel more comfortable pestering FLO if needs be.

  15. M82 - Cigar Galaxy, 200 subs @ 15 seconds stacked with Siril and processed with StarTools (although I did a quick-and-dirty test process with GIMP that resulted in an image that wasn't significantly different from this one). I am very disappointed that I got no hint of the nebular flare that is supposed to extend above and below the galactic center. Apparently, I need many more subs to get that feature. A shame, as I would be reasonably pleased with this image if I didn't know about the nebula I failed to capture.

  17. Having been getting used to using Affinity Photo 1.8, it suggested updating to 1.9. However, I could not get it to work. I started a post on the Affinity forum, had a reply with somebody with the same problem, then another post gave the solution which said it seems to be a rather common issue on notebooks with integrated Intel graphics cards. You have to make sure you have the latest (Jan 2021) driver from Intel installed. So I discovered Intel's Driver and Support Assistant (very straightforward to use), and now version 1.9 appears to work fine. Allan

  18. 3/02/21. 10.30pm to 1am. Did I really want to venture outside in close to freezing conditions, get all the equipment out, level, align and wreck a night’s sleep? Below is my answer. Ten VV galaxies in Leo VV 1364 a pair of spirals distant from each other but connected by a bridge of stars – classification PDb and at mag 17 and tiny but still be able to pick up the bridge was a real thrill. Scrutinising Aladin, the circled fuzz in the close is a compact galaxy group – no other info. VV 396 slightly brighter at mag 15 but still tiny and the classification of

  21. I didn't want to hijack any previous mount discussion threads so I am creating a new one. We have been doing astrophotography for a couple of years with mostly mass market equipment. Wanting to take things to the next level we purchased a Sharpstar 140 PH refractor (TEC 140 out of reach .. ), and needed a more robust mount than the hyper-tuned CGEM II we had been using - it did work, but required much patience and attention... After much investigation like many on here have done, I decided to contact Lucas Mesu about a Mesu 200 MkII. I really wanted a variable latitude solution

  22. Not at all surprising! A lot of us have multiple Orthoscopics specifically for lunar and planetary views. Why? Because they're so good at it! Really really dedicated planetary perfectionists use monocentrics, but I've never tried one and 30 degree afov... nah, I'm quite happy with my more-versatile Ortho's! Ant

  28. A new tiny scope build by tomy brand between 1985 and 1986 for halley comet. Lot of people knows this brand not for scope but for toys. Full plastic, focuser is not present you need to turn the body of scope for reaching focus. As it is plastic not very precise but it works. For optics part, it was made by konica/borg doublet was base on ED glass. Chromatism was very good for the fast ratio. Sold 35GBP whent it get in market. For conclusion, it is more a mini borg than a toy and at affordable price. Will push pictures of it and picture took with phone on eyepiece directl

  29. M1 - Crab Nebula 130 10-second subs stacked with Siril and processed with StarTools. Alas, yes. I know I still have squishy stars. Auto-focus works, but guiding doesn't. PHD2 seems to hate my mount...not really designed for Alt/Az, I suppose.

  30. Hello Astronomers, I'm sharing with you my image of the Witch Head Nebula, aka IC2118 & NGC1909 in the constellation Orion, near the star Rigel. This object is very large in the sky, being 3°×1°, so I had to use my smallest telescope to deliver the wide angle and low power needed to image all of the "Witches" profile. This is a very difficult object to image using a DSLR, and a dark sky is needed to capture it in it's full glory. I thought that I'd give it a go with my DSLR, and see what I end up with... I'm happy that the end result in my image shows the shape of the "Witch

  31. Yesterday a lovely little Berlebach Report 723 and tray arrived courtesy of @Telescope40 via ABS. This tripod is tiny being just 55cm tall at its lowest and 90cm tall with legs extended but centre column at its lowest. This is a travel tripod for my AZ GTi and SolarQuest if we're ever allowed outside again. Also received a copy of Bob Argyle's double star book from @azrabella

  33. I had a clear patch last night, and despite a flurry of other issues with my gear, I was able to capture a total of 13x300s subs on IC410 with my new QHY268M and Antlia 3nm Pro Ha filter. Shot at gain 56 offset 10. This is the full field of view, only cropped to remove stacking artefacts around the edges. Uploaded in 1:1 for all your pixel peeping desires Shot with my Esprit 100 and CEM40. Very happy with the camera so far! I do notice the halos around the bright stars at the bottom of the frame, and have got in touch with Antlia about them. CC welcome, as always

  34. For those struggling, theres is an easy way to offset init / sync. It does not matter where in the world you are, or what time of day it is, or even if you have the mount connected (faking servos mode, i.e simulation) 1. Make sure your latitude and longitude settings are correct in Sitech.exe 2. Manually move your mount so it is pointing due E or W, by turning DEC only. 3. In Sitech.exe, open skyview. 4. Click on a star on skyview nearest due E or W (depending which way you pointed your scope. This message will pop up - click Sync - the offset init scree

  38. As I've owned several of all these EDs.... They're all great. The only concern is light grasp and expectations. The 80mm is very nice. It excels as a portable or quick-trip telescope, and has the oomph to do low power wide field right up to planetary at 200x, all with virtually zero false colour and great optical quality. The 100mm is very nice too.

  39. Hello, welcome to SGL. Could you be a be more precise about what you are wanting to do: - watch an internet site where an observatory is live streaming whatever observations they happen to be doing at the time - watch edited highlights of the above - book time on a telescope yourself and remotely control it to view your own chosen targets - all of these - something else

I'm hoping that NINA will also save those settings upon closing but i will check next time i connect everything up for a test. Cant thank you enough for helping me. Clear Skies Andy

  43. Be aware that the greater the magnification , the less time your target spends crossing the field of view of the eyepiece , so the greater your difficulty finding the thing in the 'scope in the first place , and tracking it once you found it. Also the greater the magnification, the greater the effect of a relatively cheap mount and tripod in making that view tremble. Magnification is not everything, and the 'toy' scopes you see advertised which boast huge magnifications are in practice very poor instruments. The general rule of thumb is that you will seldom usefully exceed a magnifi

  44. I took another look at the Orion image which had a very red background, as are all the images off the astro-modified 600D with the IR filter removed. Used Affinity Photo levels to better align the channel peaks with the following result, which I think is an improvement. What do you all think please?

  48. My 60mm DIY refractor. Only able to test on terrestrial targets, but so far so good. The oversize dew shield really knocks out side glare, and I’m not sure it will be of much use against dew but I’ll see when warmer nights come back. Using it freehand, and braced against my house, it really made M42 pop. If the stinking weather ever permits I’ll give it a good test on some faint fuzzies. I did test out my SV105 with this scope today, mostly messing around with Sharpcap, and I’m pretty pumped to get a couple hours under clear skies to push the envelope. M1? The FOV is so much wider th

  49. Excellent. I have a soft spot for Boötes as it was the first constellation I explored when I started out last spring. Alkalurops is a particular favourite, and Izar defeated me several times (needed a new scope in the end). I just saw the herdsman coming up as I was packing away last night, too late for me at the moment but looking forward to resuming our acquiantance.
