TED'S ASTROPIX: The Comparison Gallery: The ST-8E (KAF-1602E) NABG v. the ST-8 (KAF-1600) ABG Page created: 24 August 2008 © 2008-2010 Ted Saker, Jr. All rights reserved. Country of First Publication: The United States of America These works are for the personal viewing and enjoyment of visitors to this site. Any and all commercial use of these images is absolutely, strictly and totally prohibited without my consent. Remember, I sue people professionally. Besides Astronomy, it's what I live for. An obstructed horizon coupled with the summertime leaves only a few good objects in position to image from the Bad Wolf Observatory. The arrival of the ST-8E at this point lent itself to the inevitable questions: is the KAF-1602E chip in the ST-8E better than the KAF-1600 chip in the ST-8 (and its predecessor, the Genesis 16 camera)? If so, how much better? Judge for yourself whether the difference is the camera, the processing, or something else. Blue borders denote ST-8E images and red borders denote ST-8 images. July, 2010: Since the ST-8E gave way to the new ST-8XME, it is unlikely that this page will see any further updates unless I get so painfully bored that I reprocess images obtained with these wonderfully obsolete cameras. I hope that the imagers who purchased these nice cameras from me are putting them to good use. Optics: Celestron C-11 Schmidt-Cassegrain Telescope @ f/10 (except where otherwise indicated). Mount: Losmandy G-11 GEM equipped with the Gemini GOTO system.
