NGC 3344 is a wonderfully structured face-on galaxy in Leo Minor.

I wanted to have it in my collection and was able to shoot 300s subs because PHD2's new Multi Star Guiding now gives me a wider range with even longer exposure times.
Starting with my typical 120 sec subs, but switched to the 300 sec for the rest of the night, which was very helpful in getting good results. I did have to sort out some frames because of wind, but stacking in the APP is much less time consuming now ;-)

I saw Morris had the same target, too (Greetings, Morris ;-).
