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

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

As far as I can tell, there should be no difference between the settings for the Mach1, AP900 and AP1200. All three have gears with 225 teeth on both axis according to the docs. This is not the case

My Mach1 seems to work fine set to "AP1200". Jer AP1200 setting

Hi Dale, You have to update your keypad's firmare to version 4.20 beta. Yves

Hi All, The AP Keypad 4.12 has selections for AP400, AP600E, AP900 and AP1200 in the "mount type" but not selection for AP Mach1 GTO. What setting should be used with Mach1 GTO

Barbara - you maybe doing this already - but, when I had a similar problem with point accuracy being many minutes off after crossing meridian while using TPOINT, i spoke to AP and they recommended I
