It’ll be a very interesting half hour or so - particularly because I’ll be setting up in daylight and will need to polar align and then to locate the planets in semi-twilight.

Just shoot two sets of subs, one exposed for Jupiter and one for Saturn, then you layer them in Photoshop in processing. Typically you wouild mask over one target off the other. Same technique that is used for processing M42, to bring out the Trapezium detail without blowing the core when exposing to bring out the detail in the gas nebula. Of course, this is a traditional sub approach to imaging, and not high frame rate stacking for planetary, but the same concept should work for capture, just shoot two videos, one for Saturn and one for Jupiter, you take the two final images and layer mask.
