  1. That’s a tough question, although I’m surprised nobody has expressed an opinion! I see your scope is F6, but unsure of the chip size of your existing camera. For EEVA, I like to use a Starlight Xpress Lodestar X2, and Ultrastar. These are certainly sensitive, and a FOV calculator will help to assess your opinion. Whilst expensive new, it should be possible to pick up a used one of these within your budget? Tony
  2. Yes, RGGB is correct. But in Nebulosity you don't get a menu which says that. See recent similar query and answer here: The magic X/Y pair to use for this camera is 1/1. Tony ___________________ Edit: The 'sickly blue' that shows initially after debayering can be fixed by selecting the Adjust Color Background (Offset) menu item, which aligns the histograms.
  3. As I mentioned, you'd need something along the lines of one of each: Filter chamber – this is the body of the thing Camera-side adapter – perhaps T2/M42 or M48, or something else, depending on your camera Telescope-side adapter – whatever fits Filter slider – 2", probably Aux filter holder – 1.25" if that's the size filter you were thinking of using
  4. You’re thinking, perhaps of the Baader UFC system... https://www.firstlightoptics.com/baader-filters/baader-ufc-universal-filter-changer-system.html Don't be deceived by the low price, you actually need a base, camera adapter, filter slider, ... to make a functional system. But it is very good.
  5. This looks like great data. Are you just pushing too hard on contrast and saturation? Just taking your JPEG and tweaking a little gives this: ...which may not be the effect you are looking for, but the IFN features compare well with this image: Messier_81_-_82_group, which I understand was up for an APOD!
  6. Thanks, but in fact I got a response from the NINA issues folk: https://bitbucket.org/Isbeorn/nina/issues/344/failure-during-installation-windows-10 ...which is unfortunate, since my not-so-old EAGLE 2 Windows 10 system says: Time, indeed, to check with PrimaLuce Labs.
  7. Perhaps this one? https://uk.rs-online.com/web/p/couplings/0814562/
  8. Yes, but be very, very careful how you install it, taking great care to line up the rigid motor coupling with the fine focuser shaft. It can be tricky. This is the downside of a non-flexible connection.
  9. I use a Sesto Senso on an Esprit 120ED, and previously on a Quattro reflector. It works well. However, I think you'll find that Crayford focus slip is not anything to do with how firmly you can hold the focus control, but all about the focuser tube slipping on the control shaft. So a motor, per se, may not help. The ultimate should be a quality rask and pinion, but that costs! Also, I recently noticed that Primaluce Labs now do an integrated motor/focuser, the Essato... https://www.primalucelab.com/astronomy/focusers/esatto-2-robotic-microfocuser.html Tony
  10. Interesting! Some folk swear by adding a filter to the guidescope, to stop IR star bloat or mitigate seeing problems. Sometimes, even, an IR pass, although that does cut down on the available guidestars.
  11. Hmm... Tried that and get Blocking Issues: The .NET Framework 4.7 is not supported on this operating system. This is on an Eagle 2 box running Enterprise Windows.
  12. I really love these images. I've never tried this type of widefield myself, and always wondered how folk achieved great results. I do feel, though, that the answer must be in the processing. I grabbed your image and had a quick go... All I've done here is to create a copy, flatten the background, stretch the image in intensity and saturation, and then mix it back with the original. Being slightly more intelligent and using a mask would no doubt be a benefit (especially for the horrible glow I've made on the horizon.) Hopefully, an expert will be along and tell us really how to do this properly. Tony.
  13. Would like to try this, but getting an error during install. I have no idea what this means: [151C:1510][2019-10-07T11:51:27]i301: Applying execute package: NetFx472Redist, action: Install, path: C:\ProgramData\Package Cache\D3A416DC5FC75758D41B4C0158ACA69270D2A904\redist\NDP472-KB4054530-x86-x64-AllOS-ENU.exe, arguments: '"C:\ProgramData\Package Cache\D3A416DC5FC75758D41B4C0158ACA69270D2A904\redist\NDP472-KB4054530-x86-x64-AllOS-ENU.exe" /q /norestart /ChainingPackage "N.I.N.A. - Nighttime Imaging 'N' Astronomy" /log "C:\Users\PRIMAL~1\AppData\Local\Temp\N.I.N.A._-_Nighttime_Imaging_'N'_Astronomy_20191007115103_002_NetFx472Redist.log.html"' [151C:1510][2019-10-07T11:53:01]e000: Error 0x800713ec: Process returned error: 0x13ec [151C:1510][2019-10-07T11:53:01]e000: Error 0x800713ec: Failed to execute EXE package.

Have left an error report on the NINA site, but I suspect it must be I, rather than they, who needs to fix something.
  14. Surely, for light pollution, you meant to say: ”you just don't see many prosecutions.”
