Re: PEMPro with SBIG STV

Ray Gralak <rgr@...>

I agree.....
I've used an STV with two different AP1200GTO mounts and have
never used
PemPro, etc.
I now use the Remote Guide Head with an SBIG STL-11000 with a
1200GTO and
still don't use PemPro.
I've used both with the efinder to guide imaging focal
lengths up to 1200mm
with perfect results.
When doing film imaging I often did exposures up to an hour
long and now,
with CCD, routinely do 30 minute sub exposures with perfectly
round stars.
Hi Kent,

Of course you can get round stars without PEC even being enabled when
autoguiding. However, you may be losing a couple tenths in stellar FWHM (i.e.
your images would be a tad sharper).
