Hi Steve, for now I'd suggest looking for a workaround to find an alternative way of achieving your goal without using the restart preview option. For instance you might try doubling the exposure value (which should cause the current frame to be dropped in a new frame to be started) and then settin...

Steve Centralised histograms are in the images in post Dec 22nd 11:20pm. I obtained centralised histograms on the 183 cameras by adjusting offset. At least I have a systematic method now to arrive at a sensible offset setting - better than the all too common 'play around with the sliders'. The 183s...

Hi Dave, I'm not sure what you mean by centralising the Histogram. The horizontal scale goes to 2^14-1 (16383), this being a 14 bit camera, I just ommited that picture there being not much to see. (Being just a photo of the inside of the lense cap!) If you integrate under the curve, you'll get 16M, ...

... adding two pictures in-line didn't seem to work - here is the other one

Hi Dave, This is an example of the SharpCap Histogram plotted vs the FITS Liberator - ASI071MC Pro - 1ms exposure, Gain=90, Off=50 (Dark frame) You can see from the mean/median, they represent the same data, but although the FITS Liberator has a lot of extra data, but the min and max histogram data ...

Hi, I am experiencing an anomaly when using the "SharpCap.SelectedCamera.RestartPreview()" command. I have a script that moves the mount every once in a while for dithering purposes, but of course the previews continue to run. Whilst I wait until the mount has stopped moving before grabbin...

Hi turfpit Thanks. Your very comprehensive reply deserves a similar reply from me, but it might take me a day or two. Just quickly, I'm not so much as concerned with how to deduce the correct Offset (aka Brightness), as much as trying to figure out why it should be increased with increasing gain. Ie...

Hi, I subscribe to Dr. Craig Stark's "Set it and forget it" rule: https://forums.sharpcap.co.uk/viewtopic.php?f=16&t=1163#p5786 You can determine the minimum offset for each setting you use in the comfort of your home. Simply cover the lens, like you are taking darks, and set your fas...

you can turn the creation of these files on and off from scripting by assigning the appropriate value to

Thanks Robin, that's great.
