I have need to take apart and clean metal shavings out of a C9.25. I believe the particles come from the previous owner's inept attempt to mount a dovetail. It appears that I can just remove the screws from the corrector lens cell. Most of the metal particles are lodged between the glass and the cell. Some are stuck to the inside of the corrector plate and a small number appear on the mirror.

I tried a quick look through it last night and saw no image problems but the seeing was lousy and only Jupiter was visible.

The seller was selling his C11 at the same time, too. Wonder if it had the same problem. :flame:

Les,

I have taken both of my SCT's apart in the past. You can follow the same directions I did HERE They are excellent directions and when followed will provide you with a hassle free procedure. Remember to mark the front of the corrector for proper orientation when putting it back together.

It's not hard, just time consuming. If you take your time and return the corrector to it's proper orientation collimation should not be that far off and should be easy to correct.

Any other questions drop me a PM or another post.

That's a great link and it does reduce the level of anxiety about this project. I'll let you know how it turns out.

Thanks!
