Hello, With APCC/Horizons I use my AP-1200GTO CP3 to track on comets and this works well, this was the main reason to buy APCC (standard version) about a year ago. But it also worked well on NEO

Hi, A question on Optics ... Does anyone know, for certain, if there is any“optics industry standard” which defines the exact point on a focal reducer lensbarrel, to measure the length

Yves, As I think I wrote earlier, the auto-config has nothing to do with this issue. The only reason that the driver would switch sign is the driver thought that there was a pierside change. To

Backlash in our latest spring loaded gearbox is vanishingly small. It is not an issue in RA for guiding in any case. As far as Go-To, the mount will move to within an arc sec or 2 of where you command

No! Red herring!!! Rolando

Usually when the guide star moves out of the box it is because the pier flip box in Maxim has been checked. What this does is to reverse the calibration moves so that instead of the guide star slowly

I see now on the ap website that the backlash setting was for manual guiding back in the day and was removed from the cp4: "Does not have R.A. and Declination backlash control. This was initially

Thanks for letting me know, Jack. -Ray Gralak Author of APCC (Astro-Physics Command Center): http://www.astro-physics.com/index.htm?products/accessories/software/apcc/apcc Author of PEMPro:

Dave, The driver and apcc don’t have backlash controls for the cp4 because the backlash correction commands were removed from the cp4. I think the reason was that people would sometimes set the

Ray, All is fine! I got the computer back in the observatory, powered on the AP1600 and started APCC without incident. I then started TheSkyX, connected to the mount and had it go to the

Steve To add to Ray's note. What made everything click was using CCDSOFT V5 for the PEMPro calibration Wizard. My guide camera is an SBG ST-i. I had forgotten that CCDSOFT V5 came with the ST-i and

I ask because of the appc and ap v2 driver setting to remove backlash (gto cp3 only). Why not with the gto cp4? You can use a cp4 with older mounts as well so it can't be the new gear box. I see

Hi Steve, I just wanted to follow up on what you asked here but I am putting this in a new topic. You wrote: see? In response to this thread: CP4. Very peak PE 4 a-s. arc-secs, incorrectly.

Larry, Howard sent that driver out to people that previously had the park issue and they tested it for weeks, so it is surprising that you still had a problem! So, I think you should give Howard or

Hi Jack, Ok, let me know if you still see an issue once you have your computer back in service. -Ray Gralak Author of APCC (Astro-Physics Command Center):

I'd be surprised if you would ever see problems with RA backlash if you have the worm mesh properly set - and then only if you slew or manually move the mount East at a speed faster than
