Hi Alan;


Thanks..


The weather forecast was wrong last night (August 22 -  clear instead of showers), so I went after a cluster of faint deep galaxies with 20 minute Luma exposures:

The Brightest galaxy (NGC 7720)  in the image is about Magnitude 13 (bottom center) and the rest are as Mag 15 or fainter. All the faint fuzzy specks are galaxies and I haven't tried counting how many are in this image.


Unfortunately, the humidity spiked to 74% last night, and the bottom left corner of the CCD got iced over - which is why the stars near it look odd and why the sky background is patchy looking.


I still have to combine the RGB color exposures and it will be interesting to see what they add to it.


TTYL..
