Subject: New images

Hi Folks;

I posted two updated images to the DSO section:

http://groups.yahoo.com/group/Astro_IIDC/files/DSO/M101_20080823.jpg

which is my revised mono version of the M101 (four 20 minute images

effectively 80 minutes of exposure time) that I captured in August and

http://groups.yahoo.com/group/Astro_IIDC/files/DSO/NGC6922WestVeil_SouthHalf_20081001MJA.jpg

the west veil which I captured last night. I did not plan to image the

veil at all, but since it's going to be cloudy for the next few days,

I figured I try a test shot after I finished shooting M27 in LRGB last

night. To bring out the very faint veil with 7 minute exposures

required a lot of image tweaking, as it is basically not visible at

all in the raw light polluted stack.

Both images were done with a new auto background subtract when sum

stacking technique which will likely be rolled into the next Alpha

release.

TTYL..
