Description

The M51 Galaxy shown as a BW Picture.

New Atik Horizon calibration frames, for all filters, were used.

After a Atik core SW update, start april, my old calibration frames became/were obsolete.

All frames were merged together into a BW picture.

Exposures were like this:

L=57x120sec+12x60sec+2x300sec.

R,G,B=3x28x120sec. Ha=24x300sec. OIII=13x300sec. SII=20x300sec.

My home build observatory is placed in my front yard/in the "red light" polution zone, have a look here,

Stack info. available (as 16bit Tiff) if needed/on request.

Kind regards Niels
