First Light Atik 4000

Finally got out and tested the Camera. 3/4 moon and a bit misty. Target the Sculptor Galaxy.

Here are three images. First is single 10min L frame no flats or darks or bias. Vignetting in corners.

Second is a stack of 4 x 10 min L, fully calibrated with darks, bias, flats, flat darks. No vignetting.

Third a crop of the Sculptor

I am relieved that my 1 1/4 inch work once you apply flats. I still need to tweak the flats duration but overall not too bad.

Camera runing at -15 deg temp.

Image scale 3.18 arsec/pix through ED80 on EQ6 phd guiding - Imaged size reduced to 50% for uploading
