Notes: In keeping with recent weather realities (see J 900), still imaging objects I can complete in one evening.

* I tried several difference processing sets with this one ... I took a total of 250 10-second subs, and tried two different techniques. The FWHM range for all 250 subs was 2.0 to 3.5 arc seconds. For this image, I used only the subs ranging from 2.0 to 2.4 arc seconds, a total of 110 subs out out 250. I also tried using all 250 subs (and deconvolving a little more than this one), but this one is a little sharper.
