Re: Encoders, yes or no?
I doubt that price differential will remain so forever. In the mean time, after spending quite a bit of effort investigating (and in most cases addressing) the sources of tracking inconsistency and

Re: Gemini/NINA spreadsheet
Hi Franco This is where I left off on my latest attempt. I decided to temporarily take N.I.N.A out of the equation in an effort to rule it in/out. Based on this, I'm wondering if it might be a

Re: Gemini/NINA spreadsheet
Thank you Edward. I'm still running tests so I will keep the thread updated as soon as I get any significant results. I believe east and west limits do work the same but things are a big complicated

Re: Encoders, yes or no?
I violently *agree* with Chip on this one. To me, high resolution absolute axis encoders are just the latest example of Astro-Bling. To reinforce his point on the cost issue here is a concrete

Re: Gemini/NINA spreadsheet
Franco, I do not have a Gemini-1 nor experience in southern hemisphere so I cannot confirm. I would be glad to add notes to spreadsheet based on experimental findings of the group. Have others used

Re: Gemini/NINA spreadsheet
Hi Neil, well the update is that I tried using the info on this spreadsheet and I think I finally solved the issues with the flip. The ONLY thing I changed from what's suggested on this spreadsheet is

Re: Gemini/NINA spreadsheet
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

Re: Encoders, yes or no?
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

Re: Help interpret my unguided log
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

Re: Help interpret my unguided log
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

Re: Undermounted?
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

Re: Gemini/NINA spreadsheet
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

Re: Encoders, yes or no?
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?
