The PL Guide Rings are bolted to a DIY aluminium plate, which is itself bolted to some Tube Rings, so it is a reasonably rigid connection.
The PL 60mm actually replaced a very old WO 66mm Petzval, which I think was 400mm FL but it was very heavy. I had this mounted in tube rings bolted to the Mewlon Tube Rings, so I have been pleasantly surprised with the PL 60mm F4 on the Mewlon thus far.
I have read that modern autoguiding algorithms allow a ratio of 1:10, but where possible, I like to keep below this, between 1:8 and 1:5.
I am a sporadic imager, so I don't have a lot of mount data to look back on, but from memory, the Tak EM200 was guiding at 0.3 to 0.4 RMS according to The Sky X Pro.
I set up and tear down each night and have just started using T-Point in The Sky X Pro. I run a 50 point model each time I set up. I use the QHY PoleMaster for PA.
The EM200 does not have PEC but I think T-Point and ProTrack in TSX Pro have probably helped with my auto guiding, they have certainly absolutely helped with pointing accuracy.

Thanks Dennis
Appreciate it
Maybe I’m getting too obsessive over my future set up in particular guiding
I’m only going to be imaging at 1250mm but the 10” OTA is quite long at 1150mm.All I can do is bolt everything down rock solid on the new monster mount and hopefully it will all work out in the end
Cheers
