Hi again, everybody!! Thanks to your tips I was able to perform live stacking with SharpCap Pro on deep sky objects. However, I still have not been able to achieve this with planets. In fact, I did try it last night with the TS 60 tube (360mm and 60mm aperture) and a 2x barlow lens. I tried this with Jupiter and Saturn yesterday but I couldn't see a clear image (I saw an image as out of focus, I couldn't see well on the screen). Also I tried to test live stacking and I got ignored frames. Should we do live stacking with planets or just "quick capture"? I don't know if I didn't see the sharp image because my tube magnification has little scope for planets, or because I didn't set the proper gain and exposure, or because I set something wrong. Tonight I will try this with the Celestron 8 SE tube, maybe I am luckier because the increase and diameter is greater. How can I capture images of planets and / or the Moon with SharCap Pro? Thanks for your advice !!

Live-stacking does not work on planets, period.  What you want to do is shoot video, recording as many frames as you can at as high a frame rate as possible.  You do this two ways: 1) setting region-of-interest using the resolution settings so you are only capturing the planet, and 2) setting your exposure time as short/fast as you can and using medium/high gain to compensate.

 

On Jupiter you can typically only take 2-minute long videos before the planet's fast rotation blurs/smears your final image stack.  Other planets you can record much longer.

 

When you have your video, use a program like AutoStakkert 3 to create your stack and RegiStax for wavelet sharpening.

Thanks GoldSpider !!! I will follow your advice when the sky is clear, because every day is cloudy !!
