Defrosted M20

Hi guys

After regenerating the desiccant in the ST2000XCM I ventured out into the observatory last night .... the moon was very bright but it was cold, clear and still. This is one of my 2 targets from the session, I have yet to look at other pics of M8. I think this is my best Triffid so far, guiding was good and 15 of the 18 frames that I took were in focus and didn't have satelite trails. I don't know why 2 frames were slightly out of wack but there you go. The satelite crossed my path on the last shot of the night.

Anyway I hope you like the image.



p.s. Lines on bottom of image are from stacking, I left them in because I wanted the lowest star in the shot for composition. Crop is to show core of neb.

DETAILS :

75 minutes total exposure 15x300sec subs - dark subtracted
sensor temp -15c, self guided with internal guide chip
image acquired with CCDOPS, stacked in DSS, GradientXTerminator in PS5.5 with slight noise reduction/sharpening on background layer .... nothing else.
