Re: [Losmandy_users] PEC on G8.

I tested my new G8 for the first time tonight.

Had my 8" tube on it, with a barlow, and 12mm parks illuminated eyepiece. 338x.

I drift aligned the mount, then sat back and watched.

The star would stay in the square for a minute or so, then drift out about a square length, then drift back after a few seconds. It then went out about the same in the other direction, and drifted almost all the way back, but not quite. Eventually 5 minutes or so, it was outside the square and floating in that area.

I dont know how to measure this, but Im thinking its good. Ill only be imaging with a Tak FS78 480 to 630mm, and autoguiding on top of that. So I think this mount will really be nice.

Any tips on measuring the PEC? I would use Jupiter if it was up, and get an idea by placing it in the crosshairs. Anyways, I guess I can find a double star.

Also, Theres not much Dec backlash. Im pretty happy tonight, things went better than expected. Ive owned two G11s, and this G8s PEC is better. However the G11s I owned a few years ago, and things may be different now.

for autoguiding all you care about is how quickly it drifts in RA.. total

PE is only important to those that want to image without autoguiding. BTW,

that box in the parks eyepiece is pretty big.
