Description

Usually I don't go ften for Open Clusters. But this time I used it for checking my optics for reflections, and and guess what I found?

One of my next homeworks will be a mirror ring to reduce reflections and a little more collimation. I will also check if the halos come from the filter and/or my new filter slider.

Removing the mirror is a good exercise as I have to do this with my 10" as well.

Besides that I am very happywith the result, because the sky was good tonight after a nice and warm spring day and also the faint galaxies and some asteroids are visible in the picture.

This is a proof for the relatively good sky quality here in the Spessart, even though Frankfurt is nearby.
