Hi foks, I have been tinkering with this, trying different mathematical functions to define the background and fitting them to the data to see how well they do. The best I have managed so far is this Capture.JPG The original image is on the left, the background subtracted on the right. I have tried ...

Hi, on the temperature side, it does look as though the cooling on your camera wasn't working - the cooler power is recorded at 100%, but the temperature is 9.8C. My first suggestion would be to check the 12V power supply to the camera - if that wasn't on, or had a bad connection then that would exp...

Ah, clear skies - loads for a week or two in mid January, not a scrap since

@Timh, yes, you are right - if you stack the two separately then you have flexibility on where to put the comet - somewhere along its track I suppose, although in theory anywhere!

cheers,

Hi Neil, there are separate filename patterns for different types of file, and the ones for live stack raw frames can be different to videos or normal captured frames. Do make sure that you have the latest SharpCap 4.0 build and check the filename settings page - if it doesn't give you a warning abo...

Hi Neil, The issue is to do with file naming - SharpCap will now refuse to overwrite existing files in most cases (for some cases if you have just clicked a 'save' button you will get prompted to overwrite or not, but not for background saving like raw frames in live stacking). It looks as though yo...

Here we go - PlayerOne Mars-C IMX462 results Capture.JPG I should have really added a few extra measurement points around gain 60 to 100 to capture the change from LCG to HCG mode, but the raw figures are very similar to yours - ie the e/ADU closer to 3 (a bit over 3 in my measurement) and the read ...

Hi, normally I would expect linearity to run to about 95% or more with a CMOS camera - that will require optimal conditions though - I would still suspect some sort of variation in the illumination levels giving you the lower reading of 62%. I just realised I was talking rubbish about not having an ...

Hi, SharpCap 4.0.9521 and later versions should fix this issue. The problem was that some of the rules for frame sizes for USB2 cameras were incorrectly also being applied to USB3 cameras. As always, you can download the latest versions here : https://www.sharpcap.co.uk/sharpcap/downloads cheers, Ro...

Hi folks, firstly - nice image @Menno :) On the subject of the comet stacking feature - yes, you can use it from the folder monitor camera, since it does not rely on having a GOTO mount or anything like that, just being able to detect the bright blob of the comet as distinct from the stars in the im...

Hi,

thanks for submitting the report. This particular issue is already fixed in the latest SharpCap 4.1 beta, which you can download here : https://www.sharpcap.co.uk/sharpcap/sha ... p-4-1-beta
