Mirror question

Posted By Michael Greenham

Well, I thought for certain that the coatings on the mirrors were at fault and since I didn't have too much invested in this scope I decided to take out the primary and secondary mirrors and have a go at cleaning them.

After researching on the net I decided to clean with warm soapy water in the sink and rinse with distilled water afterward.

Turns out the coatings are fine and with a little light rubbing with my fingers and soap whatever was on there came off. After rinsing there were a few small water spots but I left them there and thought that the views would not be affected anyway.

Collimation afterwards was a little frustrating but I think I finally got it pretty close. I'll have to star test it to be certain.

I gained a little experience disassembling and cleaning the mirrors and it was not that complicated or scary as I thought it would be. I also took the opportunity to center mark the mirror. Everything looks new again.

Neat!
Looks like it has suction and a claw for grasping the leaf.

What audio equipment do you own?

Posted By Michael Greenham

My audio system right now consists of a Technics Direct Drive turntable SL-2000, a Sony Walkman for CD's, and IPod through a Marantz Stereo Receiver and JBL 2500 speakers. Also two Klipsch Heresey speakers.

Vintage albums through a vintage amp and speakers is oh so sweet. 8)
