Mount: 10Micron GM2000
Guiding: –
Processing: SQM Pro, PI, PS
Remark: The Helix Nebula shot during a good night at Athos Centro Astronomico. The raw frames had a very good SNR and no gradients. Hence I had not to process the pics really much. Only slight denoise, color calibration, selective sharpening, masked stretch and manual stretch, LRGB combination, selective adjustment of saturation using different masks. Final cosmetics in PS.

Remark: For the eclipse I went out to the field with my family. The photo was just a trial. Actually I haven’t been prepared for anything… The night was unusual hot for a northern german summer night as the whole
summer was.

Processing:
Stacking und Bildverarbeitung mit IRIS, leichtes dynamic stretching und leichtes colour stretching, Gradient entfernt.
Remark: M 35, NGC 2158 und IC 5157 am 19.März 2012. Entgegen den Vorhersagen klarte es gegen Abend auf. Das nahm ich zum Anlass trotz mittelmäßigem Himmel und heller Umgebung meines Borgfelder Gartens die Erfahrungen von letzter Woche umzusetzten. Habe lange mit dem richtigen Ausschnitt und astrojahn gekämpft. Wenn ich gewusst hätte, dass da noch IC 2147 gut sichtbar wird, hätte ich den Ausschnitt noch anders gelegt. Das nächste Mal werde ich drauf achten.
