Many amateurs shoot luminosity unbinned and color exposures binned 2X2. The luminosity gives precise definition to the object and the color shows just as well if it has that small binning. With binning you use shorter exposures, leaving more time for the important exposures, the luminosity. I agree with Chuck that a tiny object would be a waste of aperture. But I don't like nebulae as much as galaxies. One is a gas cloud and the other is a star city -- -in my strong opinion, the star city has intelligent inhabitants. ------------------------------ On Wed, Jan 16, 2013 8:19 AM MST Chuck Hards wrote:
Thanks Rodger. That's a great combination for emission nebulae. Any idea what the pixel size is and if any capture binning is being used? Someone was asking about how small an object could be imaged and knowing that would help narrow down targets. Of course, if people are going for "wow" factor, going as big as the FOV permits is the best bet.

The Faulkes imaging session will be done using a filtered monochrome camera using multiple exposures of various filter options (RGB, OIII, Halpha, and others). Last time we used 16 images with the various filters stacked. We also took luminescence (unfiltered) and will do the same this time.
