Hey Craig, Pulse Guide is really good for that. So good that they don't make it any more. Get a copy and solve the problem. Steve

Since the tracking measurements were made on the meridian, and the RA drift is much greater than the DEC drift then I would guess the problem is in the RA axis somewhere. I just got back from the

Hi Ray, The "E" drive is an external hard drive I use for backup and for astro related "stuff". I opened the backup copy from the external hard drive, it ran, I entered site data, closed it, and then

Yes, exactly... don't you think that the CW is bending the CW shaft with some effect along the RA axis because that CW is sticking out horizontally? (You bet!) The counterweight side of the mount

But given the orientation of the scope, I don't think the flexure is due to the OTA because it would flex in DEC only. Are you thinking the flexure is then in the RA axis, with the cw's hanging out

Steve, In the case you are describing (ThSkyX+TPoint) APCC will sync with whatever coordinates that TheSkyX gives it. How closely that sync into the TPoint model matches TheSkyX is something that I

Sorry, but that's not true. Even with perfect tracking, RA drift can occur because of even the tiniest amount flexure of the scope, focuser, and camera assembly. For instance, I can measure easily it

Yes, the encoders should be used during tracking, especially to take out periodic error due to the worm drive. From what I can see, it does this very well so I am sure the encoders are working. But

I like my Rapas to much to cover it up. I just use 2 pipe hangers from Home Depot and put it on the weight bar. Use the Rapas to get close then refine with polemaster. It works fine. The polemaster

Craig, When Roland was at NEAF, the video made by Sky and Telescope explained that the encoders do in fact maintain the scopes position on a dso and will even push back against wind

I am having trouble with this in my head. Per The SkyX, it has defined the mount position based on plate solves. APCC says the mount is in a different position. As a result of the plate solves, is not

Craig, et al. Interesting – A Supplemental question, from me. Now that you mention it, does the “Encoder Option”really only function for positioning during a GOTO? I didn’t think the

I have polar aligned the mount and without using a pointing model I get good pointing accuracy, always close to the center of the ccd sensor. I have used PEMPRO to check the alignment and it also

Chris, Sorry, I don't understand what you mean by opening it from another drive. If you have installed APCC and you cannot find the icon on your desktop, you can always run APCC from the Start menu.

Hi Steve, I think you should just use TheSkyX's Sync feature. I think there are a couple different ways to use it, like centering a star in the scope and right clicking on the star and selecting Sync

I used plastic velcro from 3M. Worked great on my Mach1's RA motor box

I got a PoleMaster for testing and I can barely get it to work hereat 19+ degrees on the Big Island of Hawaii. FWIW, I can get it to work better if I first do a polar alignment inmy Mach1's RAPAS or

Hi All, On March 28, 2017 I downloaded APCC with the activation code to run it. I saved it to my "C" drive and also a backup copy to my "E" drive. I opened APCC the night I downloaded it to set it
