Thanks very much
Jerry Lodriguss ( DSLR Planetary Guru ) advises maximum recording time at 0.5 arcsec of detail smearing due to rotation is as follows -
Saturn 5 minutes
Jupiter 2 minutes
Based on my recording frame rate of 30fps that means -
Saturn 30 x 300 sec = 9000 frames
Jupiter 30 x 120 sec = 3600 frames
At those recording periods the planets especially Jupiter would have drifted a fair way from centre of FOV
I’ll take your suggestion and try longer captures day -
Saturn 3500 frames
Jupiter 2500 frames
My DSLR is only 8 bit on video with live view resolution of 1024 x 680
At the end of the day atmospheric seeing and lucky imaging governs how much I can improve the quality of my images with my basic rig
Cheers
Martin
