Hi Pete, The command set for the Astro-Physics servo system is found in the keypad manual. I would download the latest manual from the website to be sure that your information is the latest,

I agree with you if AP starts charging additional money for a modeling software. If it come as part of future models, it's fine and good for everyone. If you do not like it, don't use. If you like it,

Field rotation! Mount may be forgiving of polar misalignment, long exposure astrophotography is not. Although some software can do alignment of rotated images for stacking. If one has such software

Hi Rick, You MIGHT be able to do this: --create a user defined data at a particular horizon-based az/alt (based upon the exact az/alt given during a "known" park, with the led centered) --when

Almost the same thing happened some time ago to my friend who at that time had his Losmandy G11 with Celestron C9.5 next to my house. A power cable to his SBIG camera was destroying in the morning

Hi Howard, Your idea will work. I was hoping for a solution only requiring TheSky, but using Pulse Guide is the next best thing. If anyone knows how to do this using only TheSky, I am very

Jerry All professional observatories use modeling and their mounts are phenomenally accurate. The reality is that no mechanical system can match perfectly the real sky. The reality in the field is

Hi Rick, Locate your LED so that centering it on the camera's chip puts you precisely into the A-P Park 1 (Reference Park) position. As you have already figured out, you use your webcam to get

Speaking of the Gemini, it had a Polar Axis Correction feature which I found very helpful for refining polar alignment. After building a decent model, centering on a star near the intersection of the

The modeling would have no effect on tracking or guiding, only on the GOTO. So turning it on or off would make no difference while imaging.

Modeling would always need to be an option that can be turned on or off. When off, the mount would act exactly as it does now. Whiling imaging I would want the modeling off and while visual observing

I guys, I want to devise a system to recover pointing when my mount loses pointing. This application is for a fully robotic and remote observatory. I use TheSky as my planetarium program to operate

Chris As you point out modeling is a software patch to fix the short comings of mediocre equipment. Adding it to my AP900 would be sorta like putting patches on your tires when there's no leak.

Hi Pete, I would like to add that there are many other failure mechanisms when using your stated H/W and S/W suite where the mount can be left tracking and eventually hit the pier. I use the same

Hi, I don't want to get into a large debate, but would like to point out what I believe, for some people, may be a misconception regarding the definitions of modeling vs. polar alignment. 1. Polar

Kent, Having a mount system that is forgiving of polar alignment error, non-orthaginal orientation and even atmospheric refraction just makes things eaiser. The technology is out there, it is

Dear group, I used the opportunity last night to pursue the transit of exoplanet HD 209458b in Pegasus. This exoplanet is particularly interesting since it is the first discovery using the

I have automated my observatory with CCDCommander on top of it (also using TheSky6, MaximDL4, FocusMax, TPoint, PulseGuide, DDWCP, Boltwood CSII). In last session (for reason unknown) my AP900GTO

How many locations do people image from? One, two, four, seven.....how about 9??? I have currently stored in my AP 'locations' five places I sometimes image from. All I have to do is select one. A

AP modeling debaters, A couple of years ago there was the same debate on this forum. I suggested then that given AP's status as the state of the art mount manufacturer, its mount control software
