Live Stacking Deep Dive Walk-through 

Sharpcap at least has a setting in the bar that shows in the bottom when live stacking is on to choose "Sigma Clipping" This uses a basic rejection algorithm to remove outliers like a single bad star trail, airplanes, etc.

No. But you can use Nina and use Live Stacking in Pixinsight. It can read the images. It’s a script called EZ live stack.

@@rickpaul9858 Thanks Rick. I have have both Pixinsight and Sharpcap Pro and would like to use Sharpcap more then just it's polar alignment. It seems to have a lot of unused features.

Sure Don. When it comes to 8 bit and 16 bit images while live stacking, I normally wouldn't bother with a 16 bit image for getting a save of the view as seen on the screen. The view on screen is already stretched and non-linear, so much of what you want those 16bits for has been messed with by stretching it in Sharpcap directly. If I'm going to save a 16 bit file, I want the stack without anything having been done to it so I can stretch and process it in another application like GIMP, Photoshop, Pixinsight, etc. That's the way I'd go if I want to try to take my livestack and spend an hour or so doing post processing to get the absolute best out of that image. However, if I'm happy enough with what I'm seeing on the final screen and don't plan to mess with it anymore, I'm very happy to save exactly as seen. That gives me a final image that I won't mess with that's ready to post on Astrobin, Instagram etc. In that case, 8 bits is more than enough to show the full range and allow minor tweaking at the time of posting.

@@lazyastronomy3348 Thanks!

Thanks Werner! For saving a stack as a PNG, typically I use the Save As button in the lower right side of the live stack bar, and choose the save exactly as seen on screen option. If that’s still saving only as FITS, check the Sharp cap preferences from the main menus at top, there might be a default in there set to fits.

@@lazyastronomy3348 Hi, thanks a lot for your quick response. I just checked it and it seems to work !!! Thanks a lot for your help !!!! Werner

John Carter Sharpcap lets you do either, and both will work. The problem with color flats is that it can sometimes be difficult to figure out the right peak to get a solid flat, which typically gave me some odd gradients in the colors. Your experience may vary. Feel free to try both and use what gives the best results for you.

royspark from the camera selection menu, choose folder monitor and then from the right side options there will be a browse button to pick the folder that has your images.

​@@lazyastronomy3348 when i try to open an image it's just black with no data.

I use a Polemaster for polar alignment, but if you look at the timings, I'm only doing 15 second exposures. At that short an exposure, you don't need to be anywhere near perfect on alignment. The stars just don't have that much time to move.

Thanks James! Glad to hear it and I hope it helps you get going!
