Hi,
This is my first run with my second DSLR cooler, this one works properly.
Decided to try something that would test it out with 8 minute subs. I tried the fox fur and cone nebula before without it, I was wasting my time.
Without the cooler exif temp was 27 celsius on a night that was 15 outside temp, with the cooler exif was 17 and outside temp was 25. Not the cooling you get with a dedicated CCD but still useful.
8" f/4 astrograph,
orion mini guider, HEQ Pro 5 mount.
Unmodded canon 1100D baader coma corrector.
8 minute subs at iso 800, total 64 minutes, darks frames applied.
Median stack in
DSS, processed in
PS 7.
Cropped image.
Cheers,
Justin.
