I found a used Deep Space Explorer 8" for sale online. It comes with a collimator and several lenses, as well as a telrad finder scope. The price is lower than any Dobsonion I've seen before, $75. I am just getting started in the stargazing hobby, especially with telescopes, so I was wondering the opinion of you kind folks. Would this be worth buying? Why or why not? Thank you!

If it works, it sounds like an excellent bargain indeed! For 75 bucks you aren't going to get anything even remotely close. Just the collimator, if it's a Cheshire, and the Telrad would cost this.

These scopes were popular in the 1990s, so it is probably 20-25 years old. But, if it's in good condition you should have no problems at all. You'll want to check the mirrors carefully for any damage, likewise the focuser etc., but these do turn up secondhand and are good to go! Really the only problems might be if it has been stored in a damp place or mishandled.

I would certainly try to inspect this scope first hand rather than buying unseen - but for the money, I might take the risk anyway - this depends on you. If you do see it, take batteries for the Telrad and check for corrosion. The eyepieces may be nothing special, but there might just be something nice there too!

      I've been processing this image for quite a long now.
      I started acquiring data the last season when I only managed to shoot 3 panels with the Canon 6D through the Esprit 80 for a total of ~7h.
      This season I restarted and I added more data and covered a wider area. So a mix of portrait and landscape panels were planned and shot with the same scope and camera. Now every pixel represents at least 3-4h of integration, some have more.
      All the above were shot from Bortle 2-3 sites where I traveled sometimes even for an hour of exposure.
      To the RGB data I added 17.5h of Ha, same story with the panels. Some were oriented N-S, others E-W. These were shot with the SW 72ED and the ASI1600 from home and Bortle ~7.
      Then I figured out I still had time and I planned and shot 9 more panels of luminance with the 72ED and ASI1600, each consisting of 1h of exposure.
      I combined all of these into an image, processed it and for the Orion nebula and Running Man nebula I also blended some data I shot last season with the 130PDS and ASI1600 from home.
      Below it's my first final version of all data combined. You can watch it in full resolution on astrobin: https://www.astrobin.com/full/jni0w8/ or Flickr: https://flic.kr/p/2iBGUXq

      Just wondering what peoples thoughts are on the pro's and con's of the different types of mounts out there? Do Dobsonian mounts have issues on non-flat surfaces (like a garden) or can Equatorial mounts ever have issues getting out of line too easily?

      This may be an artifact, but I took this shot of the Orion Constellation from the Canary Islands and it showed a small nebula around Beteleguse. Do you think this is real? The shot was taken with a dual band filter which brings out the Ha.  I initially assumed it was a camera artifact, but I took more shots with different camera positions and it was still there.  There are some on-line articles about such a nebula. My first reaction was to edit it out, but I think it might be real and only visible because Beteleguse has dimmed by over 50%.  What do you think?

      Very happy with it! Wish the sky were clear, but as we all know, when we buy astro equipment, it's cloudy! Argh!
      The telescope was collected from David Lukehurst at noon and then we travelled back to Cambridge.
