Hi Gene, yes, this one is annoying - it only affects some models (not any of the ones I have, so I can't even try to find a workaround). There are also technical reasons for the QHY cameras that I cannot auto switch the camera into still mode for longer exposures as I do for other brands - the probl...

Hi, the most likely cause is that you haven't installed the ZWO System drivers which allow windows to detect the camera properly. Without those drivers, SharpCap (and other software) cannot detect the camera. Download and install the 'Camera Driver' from this page and see if that helps : https://www...

Hi, well done on your first image! My technique for flat frames when capturing solar images is to use translucent plastic over the front of the telescope to diffuse the light from the sun. One option is the plastic inner bag from a breakfast cereal packet, which is often translucent. Another is that...

Hi, the amount of the error sounds consistent with J2000 co-ordinates being sent to the mount when actually it works in JNOW co-ordinates. SharpCap asks the mount which co-ordinate system it uses, but some ASCOM drivers report the wrong setting. This can lead to SharpCap not applying the required co...

Hi, OK, I can shed some light on some of the issues... 1) Controls vanishing briefly after focus scans - SharpCap 4.1 puts the camera into still mode for focus scans if the exposure is above about 2s - this helps avoid frames being captured during focuser moves and speeds up the scan, but can mean a...

Ah, OK, that makes even more sense then I think... The glitched frames are the ones when the camera is responding to the ROI change - I suspect if you move the ROI area around manually you will see the same thing happening from time to time. I'm not sure that there is anything to be done here - depe...

Hi, that is very weird - I will pass this question on to SVBony to see if they have any ideas, since I've run out of them! As a workaround, copying a copy of SVBCamera.dll from an older version of Sharpcap may help, but if you do that, run Sharpcap direct from the .exe file in the install folder. Us...

Hi,

I thought I had fixed this one, but maybe I didn't get it right - I will check again.

cheers,

Hi Gene, the first suggestion for this problem is to set the 'Force Still Mode' option in the controls on the right to on. This ought to help with the missing first frame problem, which tends to be an issue with some QHY cameras when used in long exposures in live mode. I have raised this issue with...

Hi, the difference between J2000 and JNOW should not put you off target by more than about 8 minutes of arc, so if you are ending up a degree or more off then J2000/JNOW is not the whole of the problem. Some things that occur to me are 1) Do you have the option to solve/sync turned on in SharpCap? I...
