I feel your pain, Franco. I am also in the southern hemisphere, using Gemini-1 and N.I.N.A. I'm having EXACTLY the same problem :( So I am watching this thread with great interest !! -- Thanks and

Very nice Moon! There are those in the OnStep group who are fascinated with very high resolution encoders.? They want to have a feed back loop that will deal with any inaccuracies that that creep

Hi Paul, Thanks for your thoughts and observations!!! No idea what could cause or did cause the RA drift to reverse on 3/14. The RA drift on 3/13 was about 200a/s in 40' with a PA error of 9.1. On

Hi Topher, A few things I see from your PHD2 log: 1. There's a significant drift in RA. May be a large mirror flop, focuser sag, or just polar misalignment. It seems to reverse direction towards the

Here is my eclipse setup, not the heaviest payload in the G11G ever but close.? I had to rebalance by adding an additional 11 lb counterweight, 81 lbs total after adding the 2" AP Maxbright and

Hi Edward, this is just what I've been looking for, I've been having a really hard time trying to config my G11 to do automated flips with NINA. I have 2 questions though, do you know if this works

I used the Askar 151 (1052mm) quad element refractor with an ASI2600MC camera.? The supporting G11G works portably well with this assembly (~32 pounds on the saddle). The lighting during the full

Doug, Looks very realistic, the same as I would expect to see in the eyepiece of a good telescope. What optics/camera did you use to take the shot?

Wayback, Never underestimate the challenges in getting a good image of a Lunar Eclipse. Paul

I do believe this is my first post! The attached unguided guidelog is from my CG-11 with several upgrades including brass worm gear on RA, new OPW blocks both axis, Gemini-II w/HT motors, somewhat

On topic, without encoders the Moon in eclipse from last night.? (I'm sure there exists better, this shot is

I tend to agree with you agree with you Chip - the cost of the encoders is pretty darn steep and the number of takers would likely be low. If folks do insist on having high res axis encoders then

There are differing schools of thought on this based on what I have observed others doing and when asked why I got a lot of different answers.? IME id

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.
