It's on the side of the box. Roland

Adding simple backlash compensation is not something I recommend. It can very easily cause system instability in Dec. PHD2 has a new adaptive compensation that might work well, but you would need to

Steve, It will be a sticker on the right side, unless it is an early CP3, which may not have one. It will be GTOCP3-xxxx. Regards, George George Whitney Astro-Physics, Inc. Phone:

Hello I am trying to find the serial number of the cp3 controller box Steve

Roland, A follow up on dec backlash. So, I should be allowing PHD to measure backlash and then applying it accordingly? I thought the recommendation was not to do that. Even without it, I have

Tom PHD2's adaptive backlash compensation MAY be able to mitigate (not eliminate) that amount. If not, you can try uni-directional Dec guiding. See pages 28 and 29 of the PHD2 documentation. Bryan

Ok, I thought I had it adjusted well. I re-greased the mount a while ago, and used a dial indicator to determine the play. Ok, maybe I can set the direction of the final slew or delay Voyager for a

Yes, this is exactly Dec backlash and is typical of this mount. You can try to adjust it out, but it's not an easy thing to do. Rolando

Hi I have run into something with PhD guider that I would like feedback here first before going to their forum. I use Voyager, and the way this works and the problem is : 1) It does a precise goto to

Ron, It is more correct to refer to the program in the control box and keypad as software than firmware, so we are changing the terminology in our documentation and website. The most current

You can use the Sync function in SkyX since there is no Recal wording in that program. In SkyX the Sync is really a Recal, so no worries. Basically you point and click an object in SkyX, center it

There is a detailed explanation of Sync vs Recal on page 117 of APPC-Std and page 139 of APPC-Pro Intro to above says "Sync and Recalibrate are often used as synonyms in everyday use, but to APCC and

The Polar Scope Align app enables adjustments for atmospheric refraction plus “Aberration and Nutation” by default. It may be interesting to experiment with disabling each adjustment via

Thanks for posting the problem and response, I was doing it wrong myself! Terri

This same situation was answered here earlier this week. You must start TheSkyX as Administrator once so that it can register its ActiveX components with Windows, then it will work running as

Thanks Jeff I bought the Polar Scope Align Pro Watch app for my iPhone yesterday and I kept my old A-P Polar Align app as well. The Polar Scope Align app warns that the position of Polaris may not

I'm trying out TheSkyXPro, when I try to connect the camera in APPM I get: Failed to connect to camera: Cannot create ActiveX component. I opened the Win10 Services app and started ActiveX Installer

Hi Peter you might be better off asking this question in the PHD user forums, but in either case you would need to upload your guidelogs to see what was going on user group:

Last night using my 1200, Planewave 12.5 with an OAG I was getting such high RMS values that I could not take images. The guide star was bouncing all over the place. I checked balance. polar

Firmware is software, so calling it software is fine. :)
