NGC 7078, Const: Pegasus, Type: Globular cluster, Mag: 6.3, Size: 12.3'
- 2002-Nov-21 - HX916 image of
M15 (f/6.3, Meade LX10, an LRGB
composite of 7:7:7:7 minutes of exposure (Luminance from
2002-Oct-10 below, 7x1 minute RGBs binned 2x2 at f/10 from
tonight), STV guided, only dark frames applied, from home
with almost full moon (seeing 5, tracking 5.8X, 1.1Y @ 1.0
sec]). Processing: AIP (dark calibration, stacking), AIP
(color registration, color balanced using Auto Color, then
Black Sky, +200% color saturation), Paintshop Pro (cropped).
- 2002-Oct-10 - HX916 image of M15 (f/6.3, Meade LX10, 7 minutes
of unfiltered exposure (7x1 min L unbinned), STV guided,
from Oak Creek, AZ (Sedona) [seeing 6, transparency 5
(crescent moon and some smoke from a nearby fire), tracking
2.0X, 1.8Y @ 1.0 sec]). Processing: AIP (calibration,
stacking), MaxIm (default DDP).
- 7/21/01 - STV image of M15 (f/3.75, Meade LX10, track and
accumulate (4 of 20 seconds), zoom mode, from LBV).
- 9/23/00 - STV image of M15 (f/3.75, Meade LX10, track and
accumulate (5 of 5 seconds), normal mode, from LBV). I believe
the tracking motor was running slow due to cold weather at this
point.
- 9/23/00 - Poor SBIG
