Keeping a Planet Aligned while Imaging

Is there a way to keep a planet 'centered' while taking a video with Sharpcap Pro? I find myself doing small nudges to keep the planet centered before it rolls off of the imaging window.
I know that Firecap has an option 'Align Box' option that keeps it centered.

Polar alignment needs to be correct. Then use st4 or any tracking program to track a nearby star. You will need a finder-scope with a ccd camera hooked up to your pc. Use that as your tracker, and the planet should remain where you want it on the screen. I am assuming you have a goto system. If you have no tracking equipment, then get the polar alignment pretty good.

Hi,
SharpCap 4.0 has two ways that might work to do this
1) Planet/disk stabilization. Keep your camera at full resolution and it moves the planet into the centre of each frame by offsetting the image. See
https://docs.sharpcap.co.uk/4.0/#!2!Pre-processing
2) Feature tracking in Camera ROI/Centre of Mass mode - see
https://docs.sharpcap.co.uk/4.0/#Feature%20Tracking
be glad to hear any feedback on whether these meet your needs and/or which works best.
cheers,
Robin
