NGC 4631 -
the Whale or herring galaxy
NGC 4631, the whale... 21
x 300 seconds for a total of 105 minutes over two nights. First
light with Alan Gee compressor on Meade 12 inch. Seeing 5/10,
sky 6/10
the sky was so rough I had
to turn off dec guiding which reslulted in noise streaking after
stacking. Cropped a bit due to sloppy recentering.
Frames acquired, calibrated,
stacked, and pre-processed with Nebulosity, post processed with
Photoshop CS3
guiding for all was with the piggybacked Meade 80mm and DSI Pro
using PHD.
enjoy ...
