Interested above all in planetary AP, I've been out of the hobby for 8 years, after selling all my telescopes except a SW ED80 and a Vixen VISAC VC200L, the second because after cleaning the mirrors I lost some of the fastidious washers that control the distance between the secondary and the internal lens and determine, for instance, the backfocus. Now I'm trying to recreate the correct distance and recollimate it.

I'll upload some recent Saturn one of these days.

Thank you for your time.

Vittorio,

After processing the shots, I'm affraid that Saturn was too low, too noisy to publish the pictures. In addition, I'm having a bad time with the VISAC collimation after trying to guess how many washers should I put between the secondary and the spider to get decent images.

Thank you for your interest.
Regards,

Pedro
