Re: SC doesn't work with Gemini Telescope.NET ASCOM driver
Well progress of a sort I suppose - can you post the log when you get a chance please (no hurry). I have an idea that it might be because of rounding of the rates - the mount says it can do 0.012475 degrees per second and SharpCap rounds that to 0.0125 to display it and then requests 0.0125 and the mount says no - I will look into it.
cheers,
Robin

I've been in cloud and wind hell for 3 weeks straight, and looks like another week of it on the way... but I'll grab a log ASAP.
Re: SC doesn't work with Gemini Telescope.NET ASCOM driver
Robin,
I am getting the same error when I try to control my Gemini-2/GM-8 using Sharpcap 3.2 and current Ascom 6.4sp1. Windows 10x64, current Gemini.net.
Same error as reported by Calum. MoveAxis set 'axisPrimary' is an invalid value. The valid range is guiding, centering or slewing speeds.
I have been trying to centre M1 in my FOV -- using the PC HBX.

I don't know if it helps, but the Gemini ascom folks say they implement the standards compliant ascom telescope 3 interface and pointed me at the documentation for same. I position the scope with two other programs routinely and have no issues. Anything I can collect to help?

Hi Greg,
Well it looks like I never got a log file from the previous users who had this problem, so if you can capture a SharpCap log file after the error has occurred and send it to me though be a first step in perhaps working out what's going on.
Cheers, Robin

Re: SC doesn't work with Gemini Telescope.NET ASCOM driver
Funny you should mention that... I collected all the logs from Sharpcap and ascom this afternoon and ran an ascom diagnosis for comic relief.
Attached is the sharpcap log.

Re: SC doesn't work with Gemini Telescope.NET ASCOM driver
Hi Greg,
Thanks for the log, I think I can see what is going wrong. The Mount allows for 3 separate slewing speeds as can be seen in this log line
Many mounts actually allow for a range of speeds but this mount says that these are the 3 exact speeds you can use, nothing else. I suspect that what's happening is that SharpCap is converting these speeds to a different unit and a rounding error is meaning that the value that is eventually sent to the driver and asking it to move is not quite the same as the one that the driver is expecting. I should be able to fix this one I think.
Cheers, Robin

Re: SC doesn't work with Gemini Telescope.NET ASCOM driver
Hi Greg,
Please can you try this version – https://d.sharpcap.co.uk/download.html? ... 3.2.5921.0
What was happening was that the mount rate from Ascom was being converted from degrees per second into multiples of the sidereal rate and then back again and I think rounding errors in that were causing the problem. I've now made it so that SharpCap will check the rate it's about centre the Mount and move it to the nearest compatible rate if it turns out that the rate being sent isn't quite right.
Cheers, Robin

Re: SC doesn't work with Gemini Telescope.NET ASCOM driver
Thanks, Robin.
I will install it and give it the smoke test tomorrow... we are in the early stages of a major snowstorm here. But I can install it remotely... If it doesn't blow up when I try to move the mount we are probably good. Based on the weather its probably a week or two before I can try it for real.

Quick turnaround. Installed the updated version, brought everything up, connected and tried to move. Same error... sorry. However... it does park correctly. Logfile attached.

Re: SC doesn't work with Gemini Telescope.NET ASCOM driver
Hi Greg,
Let's have another go – try this version https://d.sharpcap.co.uk/download.html? ... 3.2.5922.0
I hadn't properly separated the 2 different units I was using for the movement rate (degrees per second and multiples of sidereal) in the previous version. I think I got it right this time round, but if it still doesn't work please turn on verbose logging in the general settings page and then post the log that should have extra information in if the verbose option is turned on.
Cheers, Robin
