The current guide programs PhD and Maxim DL can detect an error of 1/10 pixel that is why you can use short focal length guide scopes. I assume that the Celestron NexGuide can too. -----Original Message----- From: utah-astronomy-bounces@mailman.xmission.com [mailto:utah-astronomy-bounces@mailman.xmission.com] On Behalf Of Chuck Hards Sent: Saturday, March 26, 2011 1:57 PM To: Utah Astronomy Subject: Re: [Utah-astronomy] Celestron NexGuide On 3/25/11, Debbie <astrodeb@beyondbb.com> wrote:
I wonder if they will come out with an upgrade model next year. It seems they are on the right track. Overall, the article was positive. For $300, it looks like something I'd consider in the future if I get a better DSLR camera. I want to hear a report when you decide to use it.
Just a buzzer or beep would do the trick. Maybe somebody will discover a way to hack it. I think it's firmware-upgradeable. What amazes me is the 50mm short guidescope Orion is now selling for use with autoguiders. Im amazed the camera chips have resolution good enough to deal with the small image scale such a guidescope would provide. I didn't see any mention of an internal Barlow. _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php
