Roland and others, I just saw some great images from Derrick Farley on the SBIG site using the new .67 reducer (yielding F6 on his 12.5RC...1915mm FL) I also...
Not sure whether this is the sort of information you're looking for....but I posted a Helix some time ago using both reducers for an f ratio of (nominally)...
Jay, extremely informative and well done. Thanks. One question: did you perform Ray G's test via PulseGuide? And what were the results? Jim McMillan ... ...
Wow. A mpeg says a thousand words. Hard to deny what caused the problem. Thanks for the investigative report. At least now some of us know what to look for, as...
Thanks Jim, I have not had the opportunity to perform Ray's test. Recent PNW weather, and the lack of free time made additional tests using Ray's PulesGuide...
What confuses me is that until what, the last few months, guiding has been for the most part flawless for me. I got rid of my AO7 unit because I didn't see any...
Thanks "GM," I wish I had actually observed the motors behavior in August! I would have saved eight weeks of wasted energy, and efforts. ~ Jay ... From:...
Hi Jay, The reason I asked is because I have struggled some with DEC tracking issues as well - although not to the extent that you have. According to Roland,...
Hi Steve, Just to be sure to give credit where credit is due, Jay did all the research and write-up, not me. I'm just trying to learn by asking a few...
Hi Jim, I suppose I would describe the motor problem as semi-periodic. Please observe, that the graph shows nearly 300 hundred corrections, whereas the MPEG...
Steve, 1. The mounts in question are new. The problem reported is not "sudden," the problem has existed since "day one" for each mount. The problem did not ...

Roland, Great point. However, no OS used on consumer equip is a RTOS. I've not yet looked at the protocol used to perform this function - how many bytes in the...
Hi Roland, ... The accuracy of the timed pulse is dependent on the type of Windows timer used. For time-critical commands I use the Windows Multimedia timers...
I also think that it is unfair to find fault with the motor if it was not returned to AP for inspection. How in the world can they adequately respond to the...

Jay, that puts a different light on it, I must admit. If I offended you I apologize as that wasn't the intent and you should be commended for providing the...
Chris, Rest assured; I am just one of hundreds of 900/1200 users that have been getting superb guiding accuracy for many years, in both axes. There are ...

In a message dated 11/7/2003 11:28:51 PM Central Standard Time, ... The oscillation problems that you report, are they as a result of using the STV? By the...
Roland, I completely agree with you. I think that what was frustrating for me, and I'm sure for Jay, was the belief the movement could not be caused by the...
Just to make this clear to everyone... the test I put in PulseGuide was not my invention... it was purely Roland's to try to get to the bottom of some of the...
