Wow that's a beauty.

Love the lectern that sits to the side. That's a handy idea.

Fingers crossed for those clear skies for you and looking forward to hearing about first light.

It's from USA, tablet stalk by marklessastronomics. David Lukehurst made up the black pole so I could save on the cost of sourcing the same pole from USA. Just got the stand and fittings from USA.

That's a beaut of a scope - congrats!  Looking forward to hearing about your first light ;)

Enjoy!!

PS Wouldn't it be great if the paracorr had little tactile bumps so that you could feel the setting in the dark?!

Great scope. I think David Lukehurst does a top job. The fast F ratio makes a 20 inch so much more practical. Ours is F4.1 so the zenith does need some steps, but an F5 20 inch comes here annually and that really is a tall scope at the zenith.

I think you've made a superb choice.

      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?

      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. 
      John Nichol primary mirror: 37mm thickness, Suprax. Hilux coated. Optics 1/8 PV wavefront  1/27 wave RMS. Strehl .95. Secondary mirror: 62mm MA.
      Here a few photos:

      I am thinking on grinding my own lightweight mirror (first f4 16", later f4 24"). The lightest and cheapest option is to get a thin blank and slump it in a decent kiln.
      Anyone has longer term experiene with slumped mirrors? Overall doesn't seem to be more work than a normal (not pregenerated) blank.
      Do I have to grind the backside as in case of normal flat back mirrors to avoid astigmatism? How do people support a convex back while grinding? Does it make sense to grind a hole in the middle for additional support? I am remotely considering a convertible Newtonian/Cassegrain system anyway...

      Hi,
       
          Looking for a 12" DOB (or larger) which can be transported to Prestwick, Ayrshire. Any brand, as long as the telescope is optically sound and in good working order. I'm a reliable buyer who has bought and sold on this site before.
       
      Thanks,
       
      Mark
