Exactly, practical use of the mount won't improve with more encoders than those already present, unless some use case warrants this.? And most use cases were covered with Gemini.? Given its age and

Not really.? The servos just use encoders for the motor position which may or may not be well related to the actual shaft positions.? For real-time position data you need to look at shaft/axle

Some time ago Gemini and the digital servo made the few remaining advantages for absolutely encoders impractical.

As would some other folks, but you have to convince Scott Losmandy to do that. Ideally this would require a new generation of Gemini (Gemini-3?) with the necessary additional hardware and firmware to

Better! A bit of follow-up to my GM811G with poor Dec guiding for SVX140T: I followed a few of the great suggestions, namely reducing the CW moment arm and Dec guiding aggressiveness. i ordered a 21

I use my? upgraded 2010 Losmandy G11G for imaging. The wish list would be to improve guiding using absolute encoders.? If my understanding is correct, the E port on the Gemini-2 is not designed to

Yes, always do calibration and GA each run. Dale

This can make all the difference. Seems more like a settings or software issue than

My setup is 27Lb, on a G11, and I have it balanced as best I can. I Keep the one 21Lb counterweight as high up as possible. It does seem to help. Same thing for me with NINA TPA and then PHD2 tells me

Thank you Mark, Yes, on this particular guiding session, I do recall Dec was almost perfectly balanced, rather than a little camera heavy. I was having a bit of trouble getting the balance correct

Thank you John, These are also some of my thoughts. Moment-arm especially. RA,Dec cables checked. Dither is after 6-8 frames, and frequently is RA only, spiral. I have always (over the life of the

Thank you for the input! Inline answers: In general, occasionally good (0.41" RA, 0.41" Dec, 0.59" RMS was best I've seen back in October 2024), mostly so-so to bad PE/guiding (0.8-1.2" RA and Dec,

Your DEC may be too perfectly balanced, and your polar alignment may be too good. Seems contradictory but if there is any backlash in your DEC then every time you correct (say) a negative DEC error

Hi Ryan,? Did you get this resolved?? I'm seeing the same behavior - though not quite so bad.? I sent my mount back to Scott due to RA oscillations.? He was able to resolve this, and the mount

Dale, This seems bizarre behavior. Dec (which should be in red) typically will drift in one direction if PA is off. If seeing is bad it should vary randomly. Having a repeating pattern I think is

Definitely not under mounted.? The generally used rules for determining imaging payload for commodity mounts do not apply to better mounts like Losmandy.? The GM811G has a stated saddle payload for

Some questions for you.? First, w hat did the PE look like before it started to misbehave?? Generally when a system is guiding well it generally will continue to guide well until you change
