Astroscan
Hi Roger, I recently took my Astroscan apart to clean the optics,, replace the foam pad behind the primary mirror (the pad breaks down over time and the primary goes out of adjustment) and collimate the scope on reassembly. Not a job for the faint hearted. If you do a search on Gary Seronik Astroscan you will find some excellent tips. The scope is collimated at the factory, but adjustments can be made by shimming the glass plate that holds the secondary. Cleaning is the usual distilled water, drop of washing up liquid and lint free cotton ball method. The main problem I encountered was releasing the split ring that holds the primary and remounting the primary without touching it - the primary needs to be pushed back slightly against the pressure of the foam pad so that it is held in place by the split ring. The whole process is possible but a bit tricky.
Good luck. If you are still uncertain after reading what Gary Seronik had to say about it, feel free to PM me and I can provide a bit more detail about what I did.
