Description

16.5 minutes of unguided 30-second sub-exposures. Most of the sub-exposures were shot during gaps between passing clouds. When there were no more gaps, I could take no more sub-exposures. I had hoped for at least a half hour of total exposure time but it was not to be.

No darks or flats, but bias frames were applied. Flats will be applied for final processing. My quick attempt to remove light-pollution gradients has resulted in some areas of the background that are darker than they should be. I need to work on that. But the amount of dust revealed in only 16.5 minutes of exposure is promising.

The Meade LXD55 SN6 is a 6-inch f/5 Schmidt-Newtonian.
