I got first light tonight with my 10" F11. I am positively tickled! Even with what turned out to be poor collimation (one of the tube sections was not snug), this was the finest view of Jupiter I have ever had. Io's shadow was crisp. I was so excited I forgot to look for Io! :-)
Mechanically, this is a Dob mount using 3/4" Baltic. The base is 24" diameter using Teflon/Ebony Star (or Ebony look-a-like...I'm not sure). I used 12" diameter alt bearings, again with Teflon/Ebony Star.
The motions in alt/az were smooth with a perfect amount of stiction. Even with a 14mm 100 Explore Scientific eyepiece barlowed, objects were easy to get into the field of view and keep there.
Wobble and vibration were not much of an issue to my surprise. At top mag vibrations dampened in less than a second and wobble continued for only up to 4 seconds depending on the altitude, but closer to zenith wobbles were again very short-lived.
I nervously attached the 21 lbs Explore Sci refractor on my custom mount attached to an alt bearing and the 10" scope barely even noticed it. The mount is exhibiting great balance.
The OTA is not painted (blonde wood on the inside) so contrast was down quite a bit on the Orion Nebula, but the seeing/transparency tonight is very difficult anyway.
I am about half-way done with a custom EQ platform which will add another 5.5". Currently the eyepiece is 104" off the ground.
I've got a list of about 10 must-do enhancements to keep the scope safe and more usable as a result of my trial tonight, but I am very pleased with it's performance.
More to come,
