After some final tweaks, "Electa" is done. She is named after my great, great, great grandmother, Electa Ann Grubaugh Hissong who lived from 1841 to 1934.
Close-up of name tag I had made. You can see a piece of brass stock I temporarily attached as well. This will be replaced with a counterweight system from Scopestuff.com.
Here is the secondary ring with a Protostar, 3-vane spider and secondary. The secondary is heated using Protostar's built in dew heater. The light baffle on the other side of the ring is made of Kydex and I attached some Protostar flocking paper.
The focuser is a Kineoptics HC-2. Dennis Steele from Dobstuff.com made the spider brackets focuser board. The struts and strut seats are made by Moonlight Focuser.
"Electa" and "Ada" side by side. This has been a great project. I had so much fun and I learned a great deal. First light was last night and I noticed I had the truss tubes cut about and inch short. I was able to compensate for it by using spacers on the focuser. The action was stiffer than I would have liked too. This evening, I applied some Turtle Wax Express Shine Spray wax to the laminate bearing surfaces and the scope moves just like my old Obsession. I observed M81, M82, M37, and Mars this evening. I cannot wait to get her under dark skies!

Jason,
Congratulations! The scope looks great, glad the mirror has found such a majestic home.

Thanks Richard! I was hoping you would see it :)
BTW.. the mirror is excellent. Really nice star test. Better than 1/8th wave at least.
