Quote:And this is the only test I did with factory supplied PEC on. I know I could get it better under steady skies but it guides so well don't see any reason to bother, other than for bragging I do love this mount.I have not done my Mach1GTO yet, but again it guides so well I don't need to know.

Quote: Quote:Anybody know how Pempro compares to Celestrons Free Pectool?? The free PECTool works fine to remove the fundamental and harmonics of my CGE. What remains is gearbox noise that cannot be removed by PEC - so there is no benefit in reducing the fundamental further.I just record 8-10 periods while autoguiding, and the PECTool averages them and loads them into the mount. No bells or whistles, but works great.Examples of my autoguided results, with PEC trained by PECTool, are at:CGE images guided with PEC trained by PECTool Just to be clear, I train PEC by autoguiding, and I image with PEC enabled - since it does reduce the work done by the autoguider. I see no conflict between PEC and autoguiding, and PEC during autoguiding does seem to help when in the 2" fwhm regime.Frank
Quote:Miguel,Do you have a corrected curve to share? My buddy has a SXD and soon I hope to run Pempro on his mount and see what kind of corrected results we can obtain.
Quote:Ok, I did a couple PemPro runs tonight with the 1200, seeing was not great but what an improvement over the factory curve. Or maybe I just have it broke in and should have run it earlier. I will try to refine it when we get some better conditions. But it went from 1.55 to 0.66 peak to peak. I can live with that.
