Description

The Luminance was made by integrating all the subs together. I also included the NIR subs with the red during integration.

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.

Revision B 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.
