Beautiful night for imaging!
Moon Race Relics pass in the night
Animated GIF of Apollo 12 Saturn Booster (3rd Stage) designated J002e3 and a streak from another satellite.
The booster is at the arrow in the thumbnail image above. Movement is from lower right in image to upper left.
The thumbnail is frame 45 of 50 and shows a satellite that passed thru the FOV, leaving a streak in the image.
The satellite has been tentatively identified as Cosmos 382, which was an unmanned test vehicle from the RUSSIAN Manned Lunar Program, launch in early 1970!!
Now what are the odds of catching TWO 32 year old relics from the manned moon race in the same 10x13 arcminute field of view???

Animation file size is approximately 500kb, so it loads rather slowly via modem (approx 1:35 @ 56k)
50 thirty second integrations taken 40 seconds apart from Fort McKavett, TX, 10/5/02
10" SCT @ f/6.6, Cookbook 245, conditions were windy (images show buffeting)
WCMY Image taken 23:30 CDT 6/17/01. All exposures 0.0008 sec Seeing was VERY poor.
B/W image is predicted features using "Mars Previewer" (and is NOT an image)

WCMY Images, 14.5"f/5 Newtonian
(White = 2 minutes, Cyan = 2:15 minutes, Magenta = 2 minutes, Yellow = 1:30 minutes)
Both images were composited from the SAME files! The only difference was in the processing of the White Image. The difference, to me, is simply astounding. The stars are tighter, the color balance is "better" (IMHO), and there is far more detail. I have a LOT of "re-processing" to do on all the rest of my images!!!!!!
The White Image for the RIGHT WCMY image was processed using the Digital Development Process introduced by Dr Kunihiko Okano at the "Image the Sky-98" conference in Salem, Oregon. Kunihiko's description of the "DDP" technique can be found on his website at:http://www.asahi-net.or.jp/~rt6k-okn/ . I used Richard Berry's CB245.exe to perform the DDP technique on this image. Al Kelly outlined how to use CB245.exe to perform the DDP technique. In addition, Bruce Johnston has instructions on how to use his SUPERFIX package of software to also be able to perform the DDP technique.
M 17 (Swan Nebula)
WCMY Image, 14.5"f/5 Newtonian
White = 11 minutes, Cyan = 4:30 minutes, Magenta = 10:30 minutes, Yellow = 7 minutes
Note: Color Balance is way off due to shooting thru cirrus clouds
M 20
Trifid Nebula
LRGB (60:55:55:55), HX916, AstroDon LRGB filters, Orion ED80

Beautiful night for imaging!
WCMY Image, 5"f/6.8 Maksutov
White = 5.5 minutes, Cyan = 6 minutes, Magenta = 4.5 minutes, Yellow = 3 minutes
Compare this monochrome image with the preceding WCMY image to see why the extra effort required to produce color images so so worth it!!!
M 20
Monochrome Image, 14.5"f/5 Newtonian
8:00 minutes (32x15sec)
M 101
Monochrome Image, 14.5"f/5 newtonian
21:00 minutes (60 sec x 21)
GammaLog Stretch, PowerLaw Unsharp Mask
Hubble's Variable Nebula (NGC 2261)
URGB Image, 32"f/4 Newtonian
8:00 minutes Unfiltered (32x15sec), 2:15 minutes Red (9x15sec), 5:30 Green (22x15sec), 6 minutes Blue (24x15sec).
NGC 2217
URGB Image, 32"f/4 Newtonian
6:30 minutes unfiltered (13x30sec), 4:30 minutes Red (9x30sec), 7:30 minutes Green (15x30sec), 10:00 minutes Blue (20x30sec)

28 Derotated Images |
28 Images without Derotation |
Monochrome Image, 14.5"f/5 Newtonian. 14:00 Minutes (28x30sec) |
|
The 28 raw images were all rotated with respect to each other due to the field rotation system having malfunctioned on my scope. They were all derotated and then tracked and stacked using Multi245.exe's new derotate capability. A beautiful image was salvaged from a hopeless mess!!! Its hard to believe these are from the same set of 28 images!!!
This technique for derotating images can also be used by scopes on alt/az mounts (SC's on a fork with no wedge) that do not have a mechanical field de-rotation system.
NGC 6781
Monochrome Image, 14.5"f/5 Newtonian
7:15 minutes (15 sec x 29)
GammaLog Stretch, PowerLaw Unsharp Mask
NGC 891
Monochrome Image, 14.5"f/5 Newtonian
6:00 minutes (30 sec x 12)
This image is also a case study in having to rotate the images in a stack before stacking them
12 individual images all rotated with SUPERFIX to match rotation of first image, then all 12 were stacked using SUPERCAL, then linear Streach and Advanced Loop (x3) processing with SUPERFIX
