I found some Luminance images of M106 in a dusty corner of my hard drive (been there since May). I didn't have any dark frames 'handy' so I integrated the frames anyway
I use CCDAutoPilot5 to control my imaging sessions and use dithering between exposures.
I submit this question out of curiosity: am I 'wasting' my time capturing, in this case, 160 minutes of darks?
OTOH, I'm open the the idea that:
a) I'm doing it wrong
b) I'm interpreting the results incorrectly
Attached are two screen shots showing the FITS header after integration, using identical parameters.
