The optics are on the way. Hope to put together something interesting (Coulter 10" F/16 Cass) in time for the moon and the planets.

Primary mirror is now mounted (clipless). Nylon tipped setscrews keep the mirror in place. Hopefully, since the primary is 1.8" thick, mirror flexure (loss of figure) should not be a problem. The mirror mounting design should help minimize temperture affects since most of the heat from the glass surfaces will be out of the light path. Best laid plans...

Should have more time to ATM tomorrow!

Primary cell and mirror cover completed. Rubber gromets used for primary collimation. Collimatable baffle installed. Hope to have the primary up on the rail in soon. The parts are done. Just have to tie it together. So far, so good...

Hi Greg,

The hacking continues... Focuser and finder installed. Now on to the secondary mount. This will be a bit more of a challenge. I could not find a short piece of, reasonably priced, 5" tubing so I may go with a 2 vane spider.

Found an "abandoned" steel dew shield in my scope junk. Cut to 3 inches length. And the ATM project continues...
