Thanks to everyone for their insightful advice concerning my Mars

imaging. I'll try again with attention to red gain and see if more

details arise, should be getting my JMI Motofocuser soon which will

Feathertouch focusers and the like!

Yep. Focussing is all sorts of Fun. With my Orion MAK scope I get mirror shift as I focus and when I double size the image for focussing it shifts nearly out of the field of view. I'll buy another focuser for it someday.

Included some images of using electrical conduit pieces as a Unibrain

adaptor. The pieces are I believe screwed into junction boxes to allow

the straight conduit pipes to attach to the box. Prices are dirt cheap

and you need to enlarge the circular opening on the Unibrain (I scraped

it several times with a penknife) and also sand down the diameter of

the conduit just slightly.

Very interesting design, and you don't wind up blocking he CCD area at all. Unfortunately I've already cut my case front up to fit my adapter in.

Like Milton I had originally hot glue gunned some plumbing pieces but

one night imaging at about 3 Celsius the glue debonded and swearing

could be heard following the falling pieces.

I haven't had that problem with my rig at -45°C. But I used Elmer's General purpose Epoxy which comes in two tubes that you mix together. It takes 2 to 4 hours to set and 24 hours to cure, but it's never come apart in several years of use.

Thanks for sharing.
