Description

The evil noise has eaten all the signal ! I've learned not to use the Eos in the summer.
The colors were really broken and beyond repair. I used the Eos data just for luminance. The RGB comes from my wide angle image of NGC 7331. 1.5h data is from my first attempt to use the RC10. Rest of the data comes from the SCT8. The image is binned (2x2, software)

Anyway, the NGC 7331 remains a wonderful galaxy to visit during the late summer.
