NGC 6946 Cepheus
Pixel 237 on 8/19/00

Below is a comparison shot taken with the PixCel 237 CCD imager. This LRGB exposure is made from short 2 minute guided exposures. Compare this to the ST-8 image taken 6 weeks earlier below left. A noticeable gain in going to smaller pixels (from 9 micron down to the 237's 7.4 micron pixels) can be seen. More importantly, seeing conditions were much better during the image on the right. Both frames are cropped out of the larger originals. Also, the 237 rgb portions were obtained unbinned.
