My main interests are faint DSO's in particular galaxies and I want to start using very short exposures of 10 seconds or less using live stacking. I like the idea of fast exposures and stacking so I do not have to worry about guiding or using an equatorial mount. I am using a C11 SCT on an alt/az mount which limits my exposures and an Atik Infinity color CCD camera. I really like this camera but think it is best for an EQ mount in order to take advantage of longer exposures. I know that the readout noise is much higher in most CCD's than CMOS and was wondering if this limits the ability of the CCD camera to use much shorter exposures. I am seriously thinking about buying a CMOS camera from ZWO because of the much lower readout noise in order to do some type of lucking imaging/observing for my EAA. Any suggestions and help are appreciated.
