hi,

Does the Gemini goto system have permanent periodic error

correction?

Yep. In addition, you might want to read the current Level 3 manual for added PEC features in this level. It's available for download at www.docgoerlich.com/manL3V10/GeminiUserManual.pdf



If you go to Rene's web page, many more questions may be answered.

Yes, the Gemini has permanent periodic error correction. In fact, it has quite

sophisticated PEC, including averaging and delay.

Hi All,

I have a couple of question about the GM-8 and GM-11.

Does the PEC need to be redone each time you power up the unit?

Is the PEC function necessary if you plan on using the guide

function of an ST-7e?



Thanks

Brian

Hi Brian,

unfortunately the answer to the first question is yes. You must

redo it each time you power up. Also, you can't slew the scope at a

non-guide speed while PEC is running. I think the answer to the

second question is no, don't use PEC if your are auto-guiding.



I have the GM-8 and only recently have gotten into deep sky CCD

imaging. I have found so far that the PEC has very little effect.

That's even when I use the autoguider to program the PEC. With the

autoguiding off, the unguided errors seem little different. Of

course, I may be doing something wrong, since I'm new at this. I

have a ST-7MXE coming next week, I hope that solves the poor

tracking I've had unguided.

I believe the PEC needs to be re-done every power up. In other words:

it's not permanent like an LX. I won't speculate on your other

question.
