M100 and many others...
The recent weekend got my cloudy so weather, but right of a new working week I got
a clear night and decided to stay up until 1am or so to catch another galaxy in this years galaxy season.
As the "reach" of my scope combined with the quite large sensors of the DSLRs I'm using does not give me a close image of M100, I decided to take a look at the star charts and frame it that way that I get as many as possible of the surrounding galaxies too into my field of view. So full of trust to the power of my coma corrector and the collimation of my 10inch Newtonian reflector.
What you see is indeed the full frame - 59xx out of 6000px of my DSLR and I'm really happy how the stars come out even in the corners:
And here a crop of M100 itself to give a better view on those fine Halpha knots:
Postprocessing has been done only using PI and full manually - so from making the calibration files down to debayer, star alignment, integration and so on and on.
