Hello all,

Last weekend I attended the local star party here in East Denmark - Avnø Star Party. It's a former airfield with nice dark skies. We were lucky to get clear skies. 

I spend the first night acquiring SII for the Pelican nebula (Image posted in the narrow band challenge) and the second night dedicated M33. Even though we had very high humidity and fog, the data came out nicely.

Almost all the time was spent on luminance and only half an hour was left for each colour channel. All 5 minutes subs. It was a surprise the color came out OK with so little data. I blended in 1,25 hours worth of old Ha data (terrible focus), and used it very subtle to boost the red channel. FWHM for the remaining data was fine at 2,2". SQM measured at 21.3.

Thanks for watching.

Great shot - some very fine resolution here - lots of granular detail in the disc (stars!).

Thanks for the comment.  The seeing was great....probably helped by the fog. Transparency still OK straight up.
