See Msg Nos. 25538, 25540 and 25544.

Actually, I think there could be some truth to it. Seems to me that the amount of Dec that the telescope traverses for each Wed, 04 Nov 2009 05:00:50 GMT tekic545 http://tech.groups.yahoo.com/group/starfish_camera/message/585 http://tech.groups.yahoo.com/group/starfish_camera/message/585 Bob, I've read that if one calibrates the guider at 0 Dec on the southern meridian, you never have to calibrate again. Just plug the actual Dec value into Fri, 09 Oct 2009 01:23:22 GMT tekic545 http://tech.groups.yahoo.com/group/starfish_camera/message/584 http://tech.groups.yahoo.com/group/starfish_camera/message/584 Bob, Thanks for your kind words. My setup is a bit unconventional, with a small FOV camera attached to moderately large, fast astrograph. But this budgetary Thu, 08 Oct 2009 10:20:05 GMT Bob Piatek http://tech.groups.yahoo.com/group/starfish_camera/message/583 http://tech.groups.yahoo.com/group/starfish_camera/message/583 Bob, Your picture has incredible detail and gives a unique perspective on this familiar object.

To give it due credit, I enclose Mon, 21 Sep 2009 15:21:03 GMT Bob Piatek http://tech.groups.yahoo.com/group/starfish_camera/message/581 http://tech.groups.yahoo.com/group/starfish_camera/message/581 Dale, There are a lot of variables that come into play when trying to answer your question. I've heard lots of numbers and I don't know where people come up Sun, 20 Sep 2009 15:48:49 GMT Dale Ireland http://tech.groups.yahoo.com/group/starfish_camera/message/580 http://tech.groups.yahoo.com/group/starfish_camera/message/580 ... On Behalf Of Bob Piatek ... Thanks Bob I place my recent astro images on the page if you scroll down. Every one guided with the Starfish... :) The only Sun, 20 Sep 2009 15:24:45 GMT Bob Piatek http://tech.groups.yahoo.com/group/starfish_camera/message/579 http://tech.groups.yahoo.com/group/starfish_camera/message/579 Dale, Very cool setup! Thanks for sharing. I'd still recommend some velcro straps for the cables though. BTW... I checked out your webcam.

I just bought a box of RJ-11 connectors, some cable and a good quality crimper. I can make a cable of Sun, 20 Sep 2009 11:16:48 GMT Lawrence D.

The Starfish requires a straight through guide port cable. With pin 1-1, 2-2, etc. This is spelled out on page 7 of the manual. Sat, 19 Sep 2009 21:25:36 GMT Lawrence D. Lopez http://tech.groups.yahoo.com/group/starfish_camera/message/574 http://tech.groups.yahoo.com/group/starfish_camera/message/574 Good. You should have seen me from 1 to 3 AM finding all sorts of SBIG cables. A phone cable, which is what SBIG uses, probably because it is more common is a Sat, 19 Sep 2009 20:26:20 GMT Douglas http://tech.groups.yahoo.com/group/starfish_camera/message/573 http://tech.groups.yahoo.com/group/starfish_camera/message/573 A wobbly USB connection to camera is what I have experienced as well. I'm aware of using rubber bands, tape and/or velcro straps to secure the cable to the
