Re: Astronomical Info link
Hi Brian,
That link was for one of the specific simulations (requiring adobe flash).? (I had to allow flash for that page (I am using edge browser))
Here's a generic link with all of the simulations

Hi all,
I have had difficulty understanding some astronomical concepts in the past and usually comprehend things better visually than reading textural explanations, '

Re: glad to have found this group!
Hello TG!
Great place to be to learn and to get going with your new G11.
I have it's newer Little Brother, GM811G HD. But my payload is very tiny, just Deep Space Object imaging.
Great

Re: Sawtooth pattern in DEC
Hi Arun,
Well, a 3 minute period is not the 4 minute worm period, so its not the RA
worm, Oldham coupler, or gearbox. And it's a DEC period not an RA period
anyway. It's also not PEC as this only

Re: Sawtooth pattern in DEC
Great -
yes i saw the good guiding there, both axis contributing roughly equal
so that's something you'll want to watch for. If it ends up that you
improve DEC considerably, you want to make sure RA

Re: Sawtooth pattern in DEC
Thanks, Brian and thanks Paul.
Yes, I always do the calibration close to the intersection of the equator and meridian because the apparent motion of stars is greatest there which would mean a good

Re: Sawtooth pattern in DEC
Hi Arun
okay i think this is pretty close to a baseline guiding
Here's some observations/recommendations
- upgrade to the latest 2.6.8 PHD release
- turn on auto backlash compensation, start with

Re: Sawtooth pattern in DEC
Hi Arun
Can you point me to the log where you followed the baseline guiding?
here's what i expect to see:
calibration successful run, followed by
GA run, followed by
15-30 minutes interrupted

Re: Sawtooth pattern in DEC
Arun, did you try to turn *on* PHD2 backlash compensation? I see in your logs that it was disabled for all the runs:
Backlash comp = disabled, pulse = 20 ms
Also, make sure to disable backlash

Another one, this time I used the GA then ran 20 mins or so with the scope perpendicular to the polar axis.

Re: Sawtooth pattern in DEC
Brian,
Here is the guidelog from yesterday. The first calibration and 12.5 minute guide run are with the scope perpendicular to the polar axis. The second calibration was done because I rotated the

Re: Sawtooth pattern in DEC
actually that's why i want to see your baseline guiding.
on one section of your guiding, it looks like pretty standard backlash that
can be easily adjusted out
on another run, it looks different:

Re: Sawtooth pattern in DEC
Thanks, Jamie. That range is similar to what I get. I will post my baseline guiding log tonight, done with the scope perpendicular to the polar axis. A I recall, this gave me numbers close to 0.9"

Re: Sawtooth pattern in DEC
As long as it is set to use backlash compensation in PHD you should be good because it adjusts itself as time goes on. You can increase it so that takes less time. I'm usually somewhere close to
