Chuck -- Welcome to AP-GTO. I think I remember you from the LX200-GPS list. A GEM normally assumes the sky is well-ordered and that the telescope points where...
I have used the pulseguide function before and it worked fine but I was trying to measure a rate with the measure rate tool with an autoguider. When I clicked...
Hi Barbara, When you press the Measure Rate button PulseGuide starts querying the mount for RA/Dec about 5 times a second. The "D" version of the chip relies...
Pempro is for periodic error. They train it before they ship them out but it does change over time and PEMPRO will allow you to retrain your mount easily....
I am using relays. I used this exact method to measure the rate about a month ago and had no problems. I can't see what is different this time that is...
Hello all, I am considering getting a Mach1 to replace my EQ6 (as it is just too much hard work doing 15min+ subs). Upto what focal length is it possible to...
Hello, my Mach1 (received about 1 year ago) was PE-checked with PEMPro right after reception. Without PEM, I had about 2.76 arcsec peak-to-peak (well below ...
Chuck, I will give you a call in the near future and see if I can answer questions you may have. I went through the same process you describe two years ago...
For those of you who anticipate upgrading to a 64 bit Windows Vista computer, I'm happy to report that there is a new Ethernet to USB Device Server that is...
Hi, Last night my 900GTO exihibited a strange behaviour when slewing at 64 times sidereal in RA. It was as if there was excessive backlash compensation...
Hello, everyone! My name is Fernando, & I have a question about the AP 1200 GTO mount. I am expecting delivery of this mount in March or April 2009, & I would...
I've used both MaxPoint and Tpoint before I got my AP900. Both worked well. But I've not found any reason to use either with the AP900 (which from a pointing...
Hi Stephen, That sounds like a problem I had that was caused by the ASCOM driver. There is a default backlash setting of 0.15sec as I recall. That's just...
I have motor stall for the first time using the Mach 1. It is pretty cold tonight by NE standards - about 18 degrees and windy, so maybe 5 degrees with...
Fernando, when I received my AP1200 this time of the year in 2007 and bought T-Point at a friend's recommendation. After spending the time learning T-Point...
I am the friend Joe refers to here. Joe has a very rigid setup with little if any flexure. He is also using a refractor. In Joe's case with a refractor with...
Sorry Roy, it was Barry. LOL....joe :) "May You Go Among The Imperishable Stars" Joe Mize www.cav-sfo.com Chiefland Astronomy Village, Fla. ... From: "Roy...
Morgan -- I'm led to believe that the cold weather issues are more voltage-related than current-related.. The AP 10A unit also supplies more voltage (15V...
Sounds like a backlash setting. I inadvertently changed my setting once and had the same problem. Took some head scratching to figure it out. I set it back to...
I concur with this. I have a 14" LX200R OTA and find that the pointing corrector used in ACP (like MaxPoint) is required at longer focal lengths. -Mark _____ ...
I've had to use Roland's process for re-adjusting the Mach1 worm mesh a couple of times due to big temperature drops. It takes less then a minute. Just...
In a message dated 2/5/2009 7:48:29 AM Central Standard Time, jey@... ... Weight load on the mount has no bearing on the amount of torque required by the...
In a message dated 2/5/2009 7:59:40 AM Central Standard Time, ... If some other program was attached to the servo, then it can set the backlash to some other...
Thank you, Roland, very clear information and instructions. I think I'll wait to make the adjustment until this weekend, when it's supposed to be near 50...
Thanks for the advice. I am planning on mounting a C-14 on the AP 1200 GTO as well as a TEC 140mm f/7 APO refractor. At first I want to start out with shorter...
Rolando, I know this is a Maxh1 thread but would this also apply to the three screw AP1200's? "...press the 64x or 600x button to make sure the motors will...
Hi Joe, The Mach1GTO method does NOT apply to the 900 or 1200 series of mounts. They do not have the spring mechanism in the motor/gearbox to automatically set...
