I did finally get the 16" LX200 to boot. grin (Although it's guts are spread out along a lab bench right now. Careful use of a multi-meter and soldering iron.) While it is disassembled, I think I will do whatever tune-up hints I can find on-line. Maybe re-grease? I gotta get a wedge made too.

In the mean time, I dusted off a 10" f6.3 LX200 and tried it out with the ST-10XE. The scope is vintage early 90's or so, but not much used with the 16" available. There was about an hour last night between the moon and the dawn, which is when I took this one. About 5 minutes each of LRGB. I used a home-made (from an 80mm Williams Optics acromat) guide scope.

Still to do with the 10" scope:
Ditch the focal reducer (which was still on the camera and focuser from the bigger scope.)
Bob's Knobs! (needs it bad.)
Take some reasonable flats. (It got light a bit too fast this morning.)

Thanks for looking. Comments welcome.

Charlie

Nice work Charles!
Maybe a little too much saturation, but looking good! wink
