Hi Mike

Good to hear the scope is coming along, for some reason i am unable to open up the pictures.

My scope is a 20 inch  F4.5 inch home made Dob based in the criege and Berry book.  The main mirror is home made, and it originally had an astro systems secondary mirror spider and heating system.The secondary mirror was changed because it was giving astigmatic images, mirror was not flat. It was replaced with a sky optics 30th wave and is now working properly.

hi jim

similar design, same book was used, but with a twist

it has webster type bearings, plop design mirror cell with wiffle tree edge support, and astrosystems spider and secondary holder like yours.

i had a twisted secondary as well, so foc i had a new one of the good people of orion optics uk to suit my 1/10 primary made by them

shame you cant see the pics mate

i now have beautiful concentric rings on polaris at 480x on both sides of focus , but my primary is still indicating being 13* when ambient is 7* so it can only get better, wish you could swear on this forum to express  my joy.

looks like its going to be a long night, bring on the veil

Sounds Good to Go?.  Are you doing a bit of backyard astronomy Mike ? I thought the Dob Mob only done Dark site's . But the temptation of a nice 20" 1/10 Big Boy in full working condition now is just to much Temptation??

Nice star testing results Mike and hope it went well. 

The Veil looked stunning through mine the other night and will have another glance in the dark skies of galloway tonight.

It's been a long journey and glad its culminated finally in a stunning deep sky  photon muncher.
