Description

The data for this image comes from multiple sources. The luminance data is from the University of Arizona Schulman Telescope on Mt. Lemmon. I didn't have enough time to get the color data I wanted, so I took that from my backyard using my C8 Edge at F7.

This was my first attempt at mixing data from multiple sources. I am happy with this result and will be trying this experiment again later.

This image is made from 36, 120 second Lum exposures on the Schulman 0.8 meter telescope and 160 x 120 second images taken through R, G and B astrodon filters on my Celestron Edge 8" with the F7 focal reducer. The imaging camera was the ASI 1600 Mono Pro.
