COMMENTS
This image is the result
of three things against me:
1) This nebula is more difficult
than I thought.
2) The STL 11k is not particularly sensitive
to Ha.
3) I need more experience processing Ha
images.
Although in the image you can clearly see
the nebula, it was very hard to bring it up. Also, since I was binning
2x2 (!!!), I didn't capture a lot of resolution,and the image is
clearly oversampled - we're talking about 7 arcsecs per pixel! Let's
call it "an experiment that I probably won't repeat"
:-)
