Hi John

Manually, with my Vixen GPDX and Skysensor 2000 combo, I get comfortable, insert a high power eyepiece (with illuminated cross hairs) for a magnification of between x300 and x400, and locate a bright star at high altitude near the equator, not the SCP. Centre the star.

Then I set the SS2K Menu command to “PEC Mode = Record” and sit there and watch the star. When it drifts, I press the appropriate RA+ or RA- motor movement key to bring the star back to centre. The SS2K correction speed can be set from x0.1 to x0.9 and IIRC I used x0.5.

I do this for one revolution of the worm which IIRC was 8 minutes (of time) on the GPDX. Having completed one revolution of the worm, the SS2K has now memorised all the small corrections I made to re-centre the reference star.

I then select the menu command “PEC Mode = Execute” for the PEC recording to be turned on and take effect.

I also find inclined bench presses with a wide grip are best for training my pec’s.

Cheers

Dennis
