Re: QHY168c Gain Scaling question

Hi, The best thing to do is to run the sensor analysis procedure from the tools menu on your camera – this will let SharpCap work out what the e/ADU numbers are for each gain value. Some qhy cameras have gain values that are sensibly calibrated (i.e. in dB), but it seems that the 168 and some other ...

Re: Initial Support for Moravian Instruments Cameras

Hi,

It almost looks like the data is being byte swapped with the low and high byte of each pixel being transposed. Could you grab an image in fits format and share it with me as that would give me a chance to look at the data in detail and see if I can confirm that suspicion.

Cheers, Robin

Re: Live Stack: Align Frames checkbox unchecks itself

Hi, Glad to hear that you worked out what is going on and that there is no ghost in the machine causing an unexplainable problem. Actually, the way that the controls work both in terms of width and being able to move between them using the tab or arrow keys is simply down to what the default behavio...

Re: QHY183C - brain "waiting for image to settle"

Hi, SharpCap installs its own private version of the qhy SDK in its install folder, and will use that version. It won't be affected by other copies of the SDK that are installed in other folders on your computer. Note that the actual hardware drivers for the device work differently – every applicati...

Re: SX cameras

Hi Bruce,

The next major version should have support for running the cameras in still mode where they only take images on demand rather than continuously. I think this will help with a lot of the issues.

Cheers, Robin

Re: QHY183C - brain "waiting for image to settle"

Hi, If you look at the bottom right you can see that the software has been waiting for a 10 second frame to arrive for over three minutes, meaning that camera has for some reason stopped responding properly. Unfortunately this seems to be quite a widespread problem at the moment with some models of ...

Re: Live Stack: Align Frames checkbox unchecks itself

Hi, There is no specific keyboard shortcut to turn that checkbox on or off, but if it was the last thing that you clicked on then in windows terms it will have the focus and receive keyboard keypresses. In particular the default behaviour for a checkbox that is focused is for a press of the space ke...

Re: Does ROI Affect Alignment Stars?

Hi,

When you select an ROI that means that SharpCap never even gets to see the parts of the image outside the selected ROI area, so cutting down the ROI will reduce the number of stars on which the alignment algorithms can work.

Re: QHY247C Offset Problem

Hi, I feel a bit like I'm asking about the Emperor's new clothes here… Why would you set the offset to 40 if that gives you an image that is too bright? There is no real magic value for the offset control on any camera – you just pick the smallest value that nicely separates the histogram peak of a ...
