IC 5146
AKA Cocoon Nebula, Const: Cygnus, Type: Bright Nebula, Mag: 10.0, Size: 20.0'x10.0'
- 2003-July-26 and 2003-July-30
- HX916 image of IC 5146 (~f/4.6, Meade LX10 OTA on
G11, an LRGB composite of 120:25:25:25 minutes of exposure
(12x10 min L unbinned from Anza on 03Jul30, 5x5 min RGBs
binned 2x2 from LBV on 03Jul26), STV guided, dark frames
applied. Processing: AIP (dark calibration, stacking), MaxIm
(contrast stretch of luminance), AIP (color registration,
color balanced using G2V, then Black Sky), PaintShop (LLRGB
layering with one round of Unsharp Masking on Luminance for
final L layering).
- 2002-July-09 - HX916 image of
IC 5146 (f/3, Meade LX10, 20
minute total exposure [a stack of 10 2 minute images], STV
guided, binned 2x2, from OCA's Anza site [seeing 8,
transparency variable 4-8, tracking 1.8X, 1.1Y @ 2.0
sec]). Processing: AIP (flat and dark calibration (darks and
flats from July 6th), stacking), MaxIm (DDP, contrast and
brightness adjustment).
