If you're finding it troublesome, then go for a cooled astro camera. The noise can then be reproduced in dark frames and subtracted from the images (calibration).
An 8" SCT is not designed to work with a full frame camera, and you will see pretty dramatic light drop off in the corners of the image, so be prepared to crop heavily. |
A cooled astro camera is on the shopping list, however money is being put aside for a EQ mount first, looking at a NEQ6 Pro. Having said that, which of the current crop of cooled cameras has a pixel size in the 8-10 micron range?
