Description

I finally received some data from another pier, pier 7, and processed this fascinating group of galaxies. The hardest part were the large stars, but I just about managed with them, I think! Pier 7 is a William Optics FLT132 F5.6 APO, with a QSI 660-WSG Mono CCD camera, all on a Paramount MX mount. From the data provided I used 11 reds, 12 blues, 7 greens and 14 luminances, all at 10 minutes long each. The integration time was thus 7 hours 20 minutes. Thanks everyone...
