Re: AP900GTO - DEC stiffness
I will second this. Please calibrate and guide at 1x.

Re: AP900GTO - DEC stiffness
Since the backlash you describe is in RA, it is not as critical to
remove it. The 600E mounts are a bit trickier to get a perfect gear
mesh, but they are still very high precision mounts. If you

Just one more thought about this oscillation. In almost all cases,
oscillation is the result of improper calibration, which results in loop gain larger
than 100%.

G2V calibation of Baader CCD LRGB filters
Dear group,

Yes, 1x is best because it minimizes the effects of Dec backlash. I have
shot with 5500mm focal length and still use 1x for guiding.

Re: PemPro and polar alignment
Sounds great Ray,
I have a clear shot of the eastern horizon, or just north of east. I'll pick a spot about 30 degrees above the horizon and expect great results.
Still about a month until ASCOM

Thanks Ray and Rick,
At present im keeping my (orion atlas)clutches
quite loose, the las t 15 miles of my trip is dirt road(aka Paris Dakar

Re: Power connector on GOTOCP2?
I got tired of wiring up the electronics (including DC power distribution)
each time I set up the mount, so I mounted all the parts semi-permanently on
a finished plywood board. The RigRunner

Re: AP900GTO - DEC stiffness
Roland has always said it is best to use 1x gor an ag rate. I can't remember why but I had a similar issue as you and once i switched to 1X guiding is perfect in dec.

Re: AP900GTO - DEC stiffness
Howard and Rick,
Thanks for the information. I'm pretty sure backlash really is set to 0, I'm
using Ray's latest ascom driver. I'll keep working on it but for now, if I
keep aggresiveness really

Re: AP900GTO - DEC stiffness
Hi Howard,
Does the precision apply to mounts like the 600? I have a small amount of backlash and was wondering if it would be useful to adjust it out( 2 mm at the end of the counterweight

Re: PemPro and polar alignement
Hi Roy,
You can always choose a declination other than 0 (up to +/-70 degrees Dec) which should open up a lot more choices in
the sky. As long as you do the Azimuth adjustment first you can choose
