TerryMcK Posted November 10, 2022 Share Posted November 10, 2022 This is a video that Cuiv, The Lazy Geek has produced showing how to improve guiding using the PHD2 software, for those who use it, in conjunction with PHD2 log viewer and other methods. It is an interesting article. 1 Quote Link to comment Share on other sites More sharing options...
AstronomyUkraine Posted November 10, 2022 Share Posted November 10, 2022 I watched this video the other night. I tried this method, but had no improvement over using Hysteresis. The CEM70 is performing far better than I hoped, so I wasn't expecting much or any improvement. I got my best figures guiding last night using the Ioptron at 0.29 RMS.

TerryMcK Posted November 10, 2022 Author Share Posted November 10, 2022 Probably works better on SW-ish German equatorial mounts. Quote Link to comment Share on other sites More sharing options...

If I'm not mistaken I think Cuiv was using a Cem60, will need to check up on that. Quote Link to comment Share on other sites More sharing options...
woodblock Posted November 27, 2022 Share Posted November 27, 2022 (edited) I use the PEC facility built into EQMOD. You can do this by running a guided session with PHD2. Then you import the PHD2 guide log into PECPREP which can analyse the waveform to produce a PEC curve which you then install into EQMOD. This worked pretty well and did improve my guiding. I should say that I have an HEQ5 mount. Edited November 27, 2022 by woodblock Quote Link to comment Share on other sites More sharing options...
