Description

Even with the 0.7 reducer I was not able to fit the Galaxy into just one panel so this is a 2-panel mosaic - about 38 hours altogether - due to the small chip of the QSI. After finishing this (and a few others) I have since removed the reducer as it seems to be faulty and adds some unfortunate coma and tilt to the images.

Ha was blended into Red before the channel combination.
