First I'd like to mention that I have difficulties posting replies to other
images as my newsserver has not shown any new pictures in this group for
almost a month. My posts through spacebanter.com have only occasionally
reached other servers. I hope my ISP gets everything running again...
Until then I'll post replies through spacebanter. Now let's see if my
newsserver at least manages to post my own images:
Richard's fine picture of the propeller nebula reminded me that I have not
imaged it myself. Unfortunately I lost focus somewhere in the middle of the
series, but had to use all pictures to get a usable signal/noise ratio.
Deconvolution in CCDsharp and resizing to 75% makes the image look more
acceptable.
Taken from the middle of Berlin with a 10" Meade ARC at f/5.7 on a G11
mount, SXV-H9 camera, 45x5 minutes through an Astronomik 13nm Halpha filter,
5 minutes each for RGB (with the red channel being a 50/50 mix of 5 minutes
red and the Halpha image)
