Hi Trev, a good test to make sure you have the right bayer pattern set is to shine a red light into the telescope (or onto the camera sensor). Try all the patterns and the one that gives a red (reddish) image is the right one. I think the auto option is likely to be fine, but worth checking. Once yo...

Hi, I'm a bit puzzled, since the PHD2 log you have included seems not to mention anything about ST4, and apart from right near the beginning (where there are 2 'star lost' entries) there appear to be no issues recorded in the log. I'd not be surprised that PHD2 would stop guiding if you move the mou...

Hi Mike,

thanks - I will try to get that to break at my end and track down why it is happening.

cheers,

Hi Bertrand, that's odd. I can see from the camera settings that you had a bit of display strech enabled, which might have been about the sort of stretch that could make the bright area. However, the display stretch is not supposed to apply to the saved image and even if it did, I'm not sure how it ...

Hi, I suspect that the raw frames saved from live stacking are 'RAW' images from a colour camera, which means that the colour information is encoded in differences between neighbouring pixels. If you zoom in to the pixel level you would likely see a chessboard like brightness pattern. Sometimes this...

Hi, the log indicates that the failure is happening when SharpCap has requested the IAMCameraControl interface from the directshow driver. It looks like the IAMCameraControl interface is found, but there is a failure trying to wrap the result as a managed object so that the C# code in SharpCap can t...

Hi, it's definitely tougher setting up in the daytime as polar alignment by traditional methods is pretty much impossible. The options you have include... * A permanent setup - or at least leave the mount in position from polar aligning at night. * Polar align at night and mark where the tripod legs...

Hi, when you are using live stacking, the 'Save with adjustments' and 'Save exactly as seen' always save the image to PNG format - these options are designed to save an image for later viewing rather than further processing, so PNG is a good format as it is lossless but compressed and can cope with ...

Hi, just to report that I have now worked this one out and have a fix for the problem. It was an odd one - it took me a long time and alot of trial and error to find out that it only happens when the 'Connect hardware automatically when opening a camera' option is turned on! Once I knew that it turn...

Hi Trev, if you were saving the individual raw frames from the camera while live stacking, it would be worth looking at those to see if any of them show a similar effect. If they do then the data coming from the camera is glitching before it gets to SharpCap. In that case, the things to check would ...
