Description

Back in Switzerland after the holidays at La Palma, I am suprised how much light pollution there is. I did not really notice that before, but now that I know how dark it can be...

A while ago I cleaned the mirror of my R200SS and readjusted everything. Tonight I wanted to see if I put everything together in the right manner. It turned out that I tightened the primary mirror to strong, so I got some severe pinching. The stars in one corner looked like little T's (see revision B). I will readjust everything this weekend.

I played around for quite a while and if I crop the test shots of M1 severely (around 50-60%), M1 itself does not look so bad. Nevertheless, another night where I learned a lot of new things (and almost froze my hands off ;)).

Best from Switzerland,

Jan
