All, Here are the first test results for my new Mach1 GTO SN#18. First the equipment and software: AP155 EDFS at f/7 Mach1 GTO w/ flat plate adaptor + two 9lb CWTs (at very end of shaft) Pier Tech

Rolando et al, Suppose I want to image something which still needs an hour prior to crossing the meridian and I am interested in a continuous session which will last three hours when the object is

i had aligned the polar scope (was not well aligned when i got it) - so these results are after that - dont know if i'm doing something wrong or .... peter sighted' to be found this to like but

Hi, I am about to get an AP 600E GTO mount and I plan on using it with an SBIG ST-4 autoguider. I was hoping someone could give me some advice about using this autoguider with this mount. Any thing

Hi Bob, The other alternate is to initialize via the ASCOM driver. I use ACP remotely (well, from the house to the back yard) and initalize this way with no problems. FYI, I've had the keypad

Peter: Perhaps not. Even a bore sighted polar alignment scope will only get you 'very close'. Is that 'very close' close enough. That depends on what you are going to do; ie. visual goto, imaging with

Does the keypad need to be plugged in when operating remotely using a computer to contol the mount? Bob

Hello everyone, The correct mount setting for using the keypad version 4.12 with the Mach1GTO is either 900 or 1200. Either setting is fine. The new beta version 4.20 which is currently being

b.holzer@... writes: No, the keypad is just another planetarium program. It does not control the motions of the motors - that is the function of the servo. All the keypad does is

i have a new ap900 mount and still learning how to use it. i do polar alignment using the losmandy polar alignment scope that i bought with the mount. after i do polar alignment using the HC and

Well, since non-orthogonality is corrected by TPoint you can skip that. Likewise, repeatable errors need not be corrected mechanically since TPoint will model them out. You are under-estimating the

Peter: Your polar alignment scope may not be aligned or adjusted or 'bore sighted' to your mount. I don't think Losmandy or AP, for that matter, adjust the reticles to be centered to the rotational

Yes, but in this case there is NON-repeatable error on top of the uncorrected repeatable error. This is the crux of the problem. So, one has to discover the source of the non-repeatable error and the

Dave: the whole point of using TPoint is that it fixes repeatable error. It will guide you in getting polar aligned, and will compensate for non-orthogonality, etc. There is no reason to "turn it

Dave, thanks for sharing your experience as well. I have been in contact with AP (Roland) and he believes my DEC issue is most likely a problem associated with my guiding parameters and not the mount

I have had a similar problem. If I turn off DEC guiding altogether, I get very smooth guiding. As soon as I resume guiding in DEC, it does that same thing that James is experiencing. Here is some

I few questions... 1) exactly how far off is it? 2) is it the same displacement no matter where you are on the other side of the meridian? 3) When you go back to the good side of the meridian, are
