James,
Yes, purple was the right color for this scope! It looks very nice.
Thanks Michelle, and the camera doesn't do the purple color justice!
The purple is actually a translucent candy, over a chrome base coat.
So in real life it has a much more 'apparent' depth. (BTW, I LOVE
powder coating, it is by far the most forgiving method of adding color
to something that I've ever come across. (normal spray paint and I
usually don't get along!)
Here's a link to the powder coat oven I recently finished:

That was no small task to weld all those parts together! Congrats on a
very nice job.
Again, thank you, I received a new Tig Welder as an early Christmas
present, and now EVERYTHING looks like it should be fabricated from
aluminum
What did you use for a mirror cell and mirror?
The mirror cell is just a simple three point arrangement, and the
Zeodor optic was ground and figured by myself and some friends at the
'03 Orange Blossom Star Party as part of a demonstration.
Here's my interferometry test results on the optic:

Of course being a true die hard ATM, I coated the optic myself in the
home built vacuum chamber, seen he

And the biggest
question of all is... how does it perform for you and your dad?
Other than one small flaw that I need to fix, it is one heck of a
double star splitter / planetary scope!
When Dad will let me pry the scope out of his fingers, I need to add
some additional support to where the Alt bearings attach to the OTA.
As-Is they are currently attached only to the 1/4" thick birch plywood
filler panels. This results in a failure of the "Bump Test" at high
powers due to prolonged oscillations from having the thin birch
plywood as the only support point. I think adding an internal plate
that spans the alt attach point and attaches to the aluminum framing
members will solve this one..
Take Care,
