Description

Astronomik CLS CCD filter used as the Lum. This filter allows me to take exposures up to three times longer than the Lum filter that comes in the Astrodon LRGB filter set. To make the final luminance I integrated all the subs from all filters.

The revision is a crop showing a 0.5 x 0.5 degree field. I have done this to make it easier to compare other images of Globular Clusters that I am imaging.
