st-2000xm first light.

Posted By Andrew Riehl

we'll I finally had a chance to sit down and try to take a serious image with the new camera. This is a mosaic of a whole bunch of shots through a Celstron 11" SCT. Resolution GREATLY reduced, this thing would be absolutely huge at even half resolution!!!!

st2k moon mosaic reprocessed....

Posted By Andrew Riehl

i may have overdone it a bit, I did the processing on my laptop and haven't been able to check it on a real computer display yet. i will readjust as necessary. I re-mosaiced using slightly higher res images, and did a better job smoothing the joints. Then applied some unsharp masking and then re-tweaked the brightness/contrast. finally, I filled in the empty spots in the black background. may be a little dim yet.
