Hi Ray, Thanks for your replies. I thing this situation is now resolved, and I’m posting this for closure and maybe for information helping others. I listened when you mentioned that most

On that subject, are you still planning on making the new gearboxes with the disengagement lever available for older AP1100 and AP1600 mounts? I'm currently doing declination balance

It is CCDWare's policy that PEMPro licenses purchased from the CCDWare site are not sellable/transferable. This is the case with most software these days. However, if you received a PEMPro license

Yes. You are right. It would be good though to allow the sale of a complete mount and allow transfer of the license. Thanks Mark Best regards, Tom

The current license agreement does not allow transfer of any version of APCC. However, we are reviewing the policy and considering amending the license agreement to allow transfers with the sale of a

Same thing with pempro. I am getting delivery of a ap1100 and they include the software. Thanks

Hi There is a mention of the pro version with encoders but not the standard in the license agreement. Thanks, Tom

Re-doing a PemPro curve will not affect the model. Modeling cannot compensate for periodic error, it can only compensate for global errors. Think of periodic error as being potholes in the road and

Tracking at the sidereal rate only works precisely at the zenith and only if the mount is precisely polar aligned. Everywhere else there will be drift. How much drift depends on your image scale and

Of your 3 questions, the 2nd one is the most pertinent and the answer to it informs the answers for the 1st and 3rd. We all live under one giant lens called the atmosphere. We all know it's dynamic

I'd be interested in the answer as well. My mount is on a tripod in an observatory and I adjusted PA the other night. I didn't update my model and guiding remained at around 0.35" RMS error in

three quick questions: In a very small nutshell, how can a pointing model improve tracking? Why would you need such a model on a scope with encoders? How much improvement can you expect in unguided

Hi Brian, As you know, I responded to you offline earlier. I will take a look at your logs and get back to you. -Ray

That still doesn't tell me what kind of motor mount it has. In any case, how long have you had the mount - since 1998 perhaps? Does it work for you? If so, then what you are doing must be

Hi folks, this one is probably for Ray - under what conditions does an APPM generated pointing model become invalid? I have been experiencing tracking/guiding issues, and when I turned off tracking

The 900/1200 mounts have spring action built into the motor mounting bracket. They require meshing the teeth properly in order to take advantage of the spring action. The very early and oldest mounts

This true for the older 2008 900GOTO? Don Anderson On Monday, August 9, 2021, 09:48:48 a.m. MDT, Roland
