Re: Valid Guide Rates for PEC on Gemini Level 4
|
This is a followup to using PEMPro and PEC guide rate. I have just restored the full PEC guide rate range 0.2x - 0.8x to the latest build of PEMPro, which I just uploaded. Here is the direct download link to V3.00.32 (or use check for updates in PEMPro's help menu): ?
? Here is also an example screenshot showing where to adjust the guide rate. Note that the East and West move distances are not the same. For example, the East moves are 0.241 arc-secs, and West moves are 0.130 arc-sec in the screenshot below. The move distance values can differ based on the number of cells used, the number of worm cycles that the PEC cells contain, the number of teeth in the worm wheel, and the guide-rate. ?

That seems to indicate the full 0.2x, > 0.5x, and 0.8x range is valid.? Which is it?
