Hi Robin,
A feature that would be nice for us that do Solar Prominence is to black out the Sun and only show the prominences.
The over saturated tool would do just the trick if it stayed on and didn't flash. Would that be something you are willing to add?

Re: Solar Masking
Hi Don,
Nice suggestion. The other potential drawback of the overexposed tool is that it only affects the image on screen, not the saved file. Would you be wanting this to go into the saved file or just the screen?
Cheers, Robin

Re: Solar Masking
Saved file also, please.

Re: Solar Masking
A feature like this could be a game changer in Solar imaging..
Combine this with something like a feature to save dual exposure values to record both surface and prominence details

Re: Solar Masking
Hi folks,
thanks to a timely prompt from Don, I have just added this feature to SharpCap 4.1.
In order to affect both the image on screen and saved data, it appears as a control in the preprocessing section on the right. Currently it sets any pixel where the brightness exceeds 99% to black. That's fairly simple for monochrome cameras , but there are some subtleties for colour cameras
* RGB modes - if any component colour is above 99% then the whole pixel (all colours) is set to black
* RAW modes - if any pixel is above 99% then the pixel and all its immediate neighbours (left, right, up, down) are set to black. This approximates the behaviour in RGB mode above, and ensures that you get full black in regions where only one channel is saturated.
I'm unsure so far as to whether 99% is the best threshold and whether the pixels should go to 0% brightness above the threshold - I would be happy to hear views on that (preferably not ones that suggest both levels being user adjustable!!! )
cheers,
Robin

Re: Solar Masking
I should add that this is not yet available in the version of SharpCap 4.1 that is available to download - it *will* be in the next update of SharpCap 4.1 though within the next week or two.

Re: Solar Masking
Hello Don & Robin,
The other day I was thinking in a similar use of the “solar masking” proposal you are discussing.
The use would be to image faint planetary satellites like Phobos and Deimos.
You clearly will understand the needs just looking at my poor images of Mars and its satellites.
It is a 1s exposure with one C14 telescope and a ZWO ASI224MC camera. I just barely got the two satellites.
While I would like to have the black mask over saturated pixels, I would appreciate, if for example, we could do live staking of the non-saturated image. In this way, we could deeply image faint objects like planetary satellites or faint double star companions.
Does my suggestion make sense?
Thank you for considering.
