Once the Live Stack button is pressed, SharpCap will immediately begin stacking frames and will display the stacked image instead of individual frames. Mono, Raw and RGB modes are all supported by live stacking, but you are likely to get the best results (and the best performance) from either a Mono or Raw mode. Select a supported camera and then press the ‘Live Stack’ button on the toolbar. In practice, you will require a camera that can set an exposure of about 1 second or more to have a chance of picking up enough stars for alignment to work.
In SharpCap 3.0 and above, all cameras support Live Stacking. Images will appear before your eyes as the number of frames in the stack grows and noise levels will drop as the final image is averaged over more and more frames. You don’t need to have a separate stacking program either as SharpCap will automatically add each new frame to the stack and display the stacked image for you.
Instead of taking a relatively small number of exposures of several minutes each to image a galaxy or nebula, SharpCap will take hundreds of images, most likely with an exposure of a few seconds each. Live stacking – a video astronomy technique – is a great way to observe deep sky objects without needing cameras capable of very long exposures, highly accurate mounts or cooled cameras. This also includes the ability to subtract dark frames and perform flat frame correction as part of the stacking process. SharpCap now has the ability to perform live stacking of multiple frames from all types of camera.
