After having used a DSLR for astrophotography for as long as I can remember I decided to step things up a notch and get a dedicated astrophotography camera. The benefits over the DSLR seemed well worth the trouble of making the change. The ability to cool the sensor and reduce noise while taking long exposures and the increased megapixel count from my Nikon D5100 were just a couple of reasons.
So I weighed the options between choosing a CCD (Charged Coupled Device) or CMOS (Complementary Metal Oxide Semiconductor) camera. There are pro’s and con’s associated with both devices. I won’t run down that rabbit hole in this article but I will point out that the CMOS devices have come a long way in the past decade where CCD’s typically dominated. I think it’s a fair statement to say that CCD’s were the standard high-end digital imaging device not too long ago, and at the same time they were very expensive and thus not within easy reach of most backyard imagers. CCD’s are still in use and provide amazing images but the cooled CMOS cameras with their relatively lower price have become the new standard used by amateur astronomers. Following that lead as well as my budget pointed me to a CMOS camera.
