Default ASTRO: NGC 4217

NGC 4217 is the “small” edge-on galaxy to the lower right of M106 in wide field images.
I imaged it with a 87% full moon recently because it looks quite bright in the wide fields. Actually I already spent two nights on it near new moon, but didn’t use the data because transparency was awful.
I found it more difficult than expected, probably partly because of the moon.
I reduced image scale to 0.68”/pixel by binning 1.5x1.5 in software.

Taken from the middle of Berlin with a 10” Meade ACF at 2060mm focal length on a G11 mount, Trius SX694 camera, 46x7.5m Lum, 12x7.5m each for RGB.
