    Big Al now lives with my Dad and he uses it a lot! Here is his channel: / @johndwilmore1075
    We take one last tour of our sky using Big Al, the refurbished 12" Dobsonian on a cardboard mount.
    In this video, we can make out the central star in the Ring Nebula. This is a tiny white dwarf, a remnant of the star that created the nebula. If I mentioned that this star once exploded, that is incorrect. What happened is after the star ran out of fuel, it shed it's outer layers into space.

    One good thing about looking at the Ring Nebula through a camera is you can look right at the image! I found through my 127mm refractor it was so dim that I could only really see it with my peripheral vision...as soon as I looked right at it, it would disappear.

      Hello Jak,
      Congratulations on seeing it through your 127mm refractor!! And that sounds like a NICE scope! Is it the Explore Scientific one by any chance? Also, were you observing in a light polluted area?
      This nebula looks awesome through our 10" dob even in bortle 6 skies. And I agree, cameras make it pop so much more!
      Clear skies,
      - Robert

      @@spacetimewithrobert4438 Hi Robert, yes it is an Explore Scientific FirstLight 127mm Achromat.
      Im in a pretty rural area on Vancouver Island so light pollution is very low, not even street lights.
      It was pretty high in the sky and the seeing conditions were pretty good.
      Cant remember which eyepieces I used, definitly a 25mm plossl, maybe a 20mm William Optic and probably and Explore 11mm 82 degree.
      Im currently looking to get a 10" dob just like the one you donated (good on ya for that!) or possibly the collapsible Sky Watcher.
      Happy Viewing!

      @@kriegschwert Wow you got a nice collection of EPs! Oh and I LOVE my 10" Dob for casual viewing/EAA and lately even short-stacking AP. For me the size and weight is perfect. 12 was too much. 8 left me wanting more. 10 is where it's at!! So easy to collimate and maintain as well.
      As long as I remember to let it acclimate, it's my favorite scope to use.
      And thank you! The donation $$$ all comes from our visitors and friends online. We made enough to afford another 10" last year, so now Carl (our AD10) is getting donated as well!!
      The new 10" for our show is already ordered and this time we're going with the ES Firstlight 10" again!! "Isaac" will be it's name.
      We also got a Losmandy G11 and we plan to mount that sucker on there for some longer exposure shots. Those mounting rings that the ES 10" comes with are so expensive!! And at $699 from woodland hills (deal ended already) I figured it was the best deal on the market for a new 10" dob.
      Anyways, I hope you get yours soon. It's so much more light gathering potential and in your darkened area it sounds like you will have a lot of fun with one!!
      Time to acclimate those scopes! Talk to you later,
