The moon 2017-10-10

Finally clear skies and a chance to do some imaging again. A 77% illuminated waning gibbous moon made deep sky photography impossible.

New edit of The Rosette Nebula using PixInsight

Using PixInsight I made a new edit of The Rosette Nebula. I think I managed to get much more detail, and a much better color balance!

I am really starting to like this new way to process my images – PixInsight! The results are getting really improved! Here is the result after processing my last image of M81/M82 again in PixInsight:

Another night with clear skies! With Bode´s Galaxy right overhead, I decided to spend the night capturing this beautiful galaxy and its smaller neighbor the Cigar Galaxy.

The Leo Triplet (M66 group)

An excellent week and weekend for astrophotography. I spent all week watching the sun during the day, and both friday and saturday night had clear skies and moonrise at about 4am. I spent the early hours of friday night (march 13th) capturing RGB-data for the Rosette Nebula. When the Rosette Nebula disappeared below the horizon, I turned my telescope to the Leo Triplet (M66 group), and managed to capture about 4hrs of good data before I had to get some sleep. The result was the LRGB-image of the Leo Triplet:

The Rosette Nebula – RGB data collected!

I finally managed to capture some RGB-data of the Rosette Nebula. After several failed attempts due to bad seeing and too much moonlight, I managed to capture a few hours of good RGB data during the night of march 13th.

This is the result of the RGB combined with the previously captured Ha-data.
