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

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

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
