M22
NGC 6656, Const: Sagittarius, Type: Globular cluster, Mag: 5.1, Size: 24'
- 2002-Sep-09 - HX916 image of
M22 (~f/4.6, Meade LX10, an LRGB
composite of 20:10:10:10 minutes of exposure (10x2 L
unbinned and 5x2 RGBs binned 2x2, from Anza), STV guided,
only darks applied to all images, [seeing 6, transparency
~20.58 mag./sq-arcsecond at zenith (63% r.h.), tracking
1.7X, 1.1Y @ 1.0 sec]). Processing: AIP (calibration,
stacking), MaxIm (DDP on luminance), AIP (color combining
and balance - G2V, Black Sky, rescale luminance,
+3B).
The color balance is really screwed up on this for
some unknown reason and I'll have to reshoot it at some
point.
