The noctilucent cloud is in the upper right of the image, hovering over some beautiful pink and purple-tinged lower level clouds just after sunset during last year's autumnal equinox. A single 1/1250s exposure at f/5, 155mm, shot with a Nikon D50. No processing. One of the most beautiful sunsets I have ever seen!

I think that that is an ordinary cirrus cloud uplit by the setting sun. Or maybe an iridescent cloud http://www.atoptics.co.uk/droplets/irid1.htm

NLCs are really only seen after the sun has set.

Thanks, Zakalwe. It's a tricky subject!

You'll know them once you see them. They really are a very unique sight and can't be mistaken for anything else.

      Hello,
      I am wanting (not really 😪) to sell my Stellarvue SV105-3SV with tube rings [not shown in pictures]. The telescope is in great condition with very little dust and no scratches. There is one very small ding in the dew shield paint but it is not dented and it is almost not even noticeable. It happened when I took the telescope out of the saddle and it lightly hit the saddle. The telescope has never been dropped or had any issues and is optically perfect with a strehl of .95 or higher (claimed by Stellarvue).
      I've only used this telescope for imaging however I've once or twice thrown an eyepiece in it during a star party or two and it's VERY crisp with no false color.
      Currently I live in Italy so that's where it can be picked up or shipped from. Price is negotiable however Stellarvue says it is worth around $1200-$1500 USD. The nice thing is you wouldn't have any VAT from Stellarvue . Please let me know if you have any questions, comments or are interested.
      Lastly, here is a link to some images that I've taken with it and what it looks like mounted up: https://www.astrobin.com/users/chriscorkill/
      SV105-3SV Specifications
      Aperture: 105mm Apochromatic Precision Triplet Focuser: 3" Dual Speed Focuser with 2" and 1.25" eye piece adapters F Ratio: f/7 Focal Length: 735mm Color Correction: Excellent Minimum Tube Length: 16" in travel mode Tube Diameter: ~ 4-1/8" (105mm) Dew Shield Diameter: ~ 5-3/8" (137mm) OTA Weight: ~12lbs (5.4kg) Retractable Dewshield: Yes

      Hello,
      I have a question about filterwheels; SBIG filter wheels specifically. As far as I know they are the only ones that really use the 8 position filter wheels. So I have it loaded with L, R, G, B, Ha, OIII, and SII. So that is seven filters, what goes in the 8th slot???
      Thank you for your insight,
      Christopher

      Hi, Folks
       I am only a few weeks into astronomy and started off with a Celestron 9.25" Evo on the standard AZ mount. I guess with hindsight this wasn't the best place to start and also with hindsight I would have done better to have bought a GEM mount. Anyway, lesson learned and at 71 years old I have to speed up the learning process compared to younger enthusiasts  I have 2 issues. 1/ Its a pain dragging the scope out into the garden and setting it up every time I think the fickled weather might be obliging. 2/ I now know that the mount I have is useless for long exposures and a wedge is fiddly to get polar aligned.
      My question is, though I gather wedges are a PITA to setup etc is if I was to build or buy a pier for the backyard and use my existing mount + a wedge is this a reasonable way to go? Though it's fiddly to set the thing up once set I could leave the mount, wedge, etc covered up and would just need to drop the OTA on when I wanted to use it.  Is this reasonable or am I missing something fundamental down near the bottom end of my learning curve
      Any advice much appreciated and don't feel you have to spare my feelings

      Hi, this question has probably been done to death here, but can I ask the community to help me decide on a new camera?
      After struggling with my very glitchy QHY5LIIc camera for a while, as well as having a forced break from astronomy, I have decided to get a new camera. After all the problems I've been having with the QHY, I really don't want to use this manufacturer again. I know lots of people use them quite happily, but once bitten ...
      I have been looking at the ZWO cameras - OSC, as I haven't the time, clear skies, or patients to do LRGB imaging!
      I have about £250 to spend, which I may be able to push to £300 if I wait a bit. ? So I've been looking at the ASI224MC, ASI290MC and the ASI178MC cameras.
      I mainly do planetary/Luna imaging, but I have also dabbled in a bit of DSO and would like to continue with both. I have a C9.25 and a ST80 guide scope. I know these aren't ideal for DSOs but please humour me!
      I think from the specs/information that the 224 is probably the best option. Although the resolution and QE are the worst of the three, the well depth and read noise are the best and the fps is pretty good too.
      I don't know if there are better/cheaper cameras using the same chips, such as Altair's range. I just don't want to make the same mistake that I did with the QHY!n
      Any help/advice you can give will be much appreciated.?

      Hey StarGazersLounge Forums,
      I am an amateur in astrophotography and have so far taken photos of the Moon and some planets with my camera. However, I am looking for a major upgrade in order to take astrophotography to a professional level as I have long been passionate about astronomy. My overarching aim with astrophotography is to take high quality photos of many planets and continue my interest with the universe.
      I would be very grateful if anyone could recommend the best set up regardless of the price at the moment as I will work from there. This includes a camera, mount and eyepiece for the Celestron 8se etc so I can get a good idea of what I need to get some amazing planetary shots. By the way, for the camera, I am considering the Sony a7r iii (good choice?) for astrophotography and nature photography as well. Any form of advice would be much appreciated.
      George
