Hi Mario, you shouldn't need any additional software for that camera - the SV105C is (I'm fairly sure) a simple USB camera that implements a thing called 'USB Video Class', meaning it should trigger default Microsoft supplied drivers to be used. I honestly can't see a good reason why the code would ...

Hi, what camera are you using? Some cameras don't actually have a unity gain, in which case SharpCap will aim to get as close as possible -usually minimum gain. Minimum gain can also give the max dynamic range is some cases, particularly with cameras that do not have a cliff edge in the read noise g...

Hi, the only real way to be sure which direction the focuser moves for higher (or lower) values is to use the software to move the focuser (say from 20000 to 25000) and watch to see what happens. This is because when you mount the focus motor on your telescope, the direction of movement will depend ...

Hi Jon, long focal lengths always bring a challenge, but your FOV of about 0.8x0.55 should be sufficient for plate solving to work fairly reliably as long as you can get enough stars clearly visible (30+ ideally). This may require some tinkering with gain/exposure settings to get a reliable setup th...

Hi, thanks for posting the log I can see that the cover initially reports as closed, then at 09:23:32.466, SharpCap requests the cover to open. For about 15 seconds, SharpCap receives a 'Moving' state from the cover, until at 09:23:46.987 it starts reporting an error state. The error state then caus...

Hi, it would certainly be an interesting feature to have :) You are right about the white balance from stars - it picks unsaturated stars in the image and tries to make them white (on average). I suspect it should really try to make them slightly yellow/orange on average, since the dimmer, unsaturat...

Hi, from the log, it looks like you clicked through a warning about the mount co-ordinates being a long way (58 degrees or so) from the sun position. That's certainly not going to help at all with the accuracy of the movements - really you should have the mount co-ordinates roughly correct to within...

Hi, there's no option at the moment to lower the frame rate further than the automatic management. The performance screenshot above though is really useful, as it shows that the bulk of the time is going into the display update. It may be worth making sure that you have proper graphics drivers insta...

Hi, yes, looks like the same problem as last time where SharpCap has decided not to save any more frames for a reason that we have to determine. I hope to get a new update out today/tomorrow which will have the extra logging to help determine what is going on. One thing I can see from that log is th...

Hi, I think a good test would be to try only connecting SharpCap to the mount and see if that works consistently. If it does then that would suggest that sharing the mount driver between different applications could be the cause of the problems with zero readouts for RA and Dec. In that case, I woul...
