After a longer break of work and bad weather I finally had an opportunity to give my new 72mm APO its first light.

Since there were upcoming clouds, it was only a short session but the first results were quite promising.
Even though the APO is somehow beyond the limits of the star adventurer and it was quite windy, the stars doesn't look so bad. Also most of the error was in R.A., so I*m positive that there is still room for improvement when I optimize the guiding.
Now all I need is better weather ;-)
