2004-Sept-21 - SXV-H9
image of NGC 6995 version 1 and NGC 6995 version 2 (Meade LX10
OTA at f/5.25 on G11, both versions Ha-Ha-OIII-SII
compositions of 160:160:270:260 minutes [Ha from below,
OIII and SII from Sept 20th and 21st, all 10 minute
unbinned subexposures], all SXV/MaxIm guided (170mm on
ST80), no calibration, Ha from Oceanside [transparency 7,
seeing 6]), OIII/SII from Oceanside (transparency 8 and
9, seeing 6 and 4), Processing: MaxIm (alignment and
stacking, DDP, color combine Ha:Ha:OII:SII), Photoshop
(luminance corrected layering), NeatImage (demo, 35%),
lots of details that I've long forgotten.

image of NGC 6995 (Meade LX10 OTA at
f/5.25 on G11, 160:30:30:30 minutes [Ha from below,
binned colors from LBV (Sept 11th)], Ha SXV/MaxIm guided
(170mm on ST80), colors STV guided (400mm on ST80), no
calibration, Ha from Oceanside [transparency 7, seeing
6]), colors from LBV (transparency 8, seeing 4),
Processing: MaxIm (alignment and stacking), Photoshop
(levels and curves, luminance layering), NeatImage (demo,

2004-Sep-07 - SXV-H9
image of NGC 6995, the wide part of the
"Eastern" Veil Nebula (LX10 OTA at f/5.2 on G11, 160
minute total exposure [a stack of 16 10 minute unbinned
H-alpha images], SXV-guider/MaxIm guided (ST80 at 170mm),
from Oceanside [seeing 7, transp 7]). Processing: MaxIm
(alignment and stacking, DDP, contrast and brightness),
NeatImage (demo).
2003-Aug-29 - HX916
image of NGC 6995, the Veil Nebula
(TV101 on G11, 120 minute total exposure [a stack of 12
10 minute unbinned Halpha filtered images], STV guided,
from Oceanside [seeing 7, transp 3-4]). Processing: AIP
(dark calibration, stacking), MaxIm DL (DDP, brightness
and contrast adjustments), PaintShop Pro (resize 50%).
2002-Oct-05 - HX916 image
of NGC 6995 (f/4.6, an RGB of
20:20:20 minutes of exposure (10x2 binned 2x2 RGBs), STV
guided, dark frames applied to all, from Benson, AZ
[seeing 8, transparency 8, tracking 1.2X, 1.2Y @ 1.0
sec]). Processing: AIP (calibration, stacking, RGB
combined, Auto Color then Black Sky color balanced),
Paintshop Pro (cropped).The Astronomik blue filter just doesn't focus the same in this filter slide. Hopefully it will in the Homeyer filter wheel.
5/13/2002 - HX916 image of NGC 6992 and NGC 6995, the Eastern
section of the Veil Nebula (f/6.3, 40 minute total exposure
[a mosaic of four stacks of 10 1 minute images for each
mosaic piece], STV guided, binned 2x2, flat and dark frames
applied, brightness and contrast adjusted, from Anza (OCA
site) [transparency 7, seeing 7, STV tracking 5]).
