Hi Allan,
I mainly image DSO but do planetary imaging from time to time with my Newts , DSLR and Televue Powermates. I’m by no means an expert but have done it now for 6 years.
Personally I’d opt for a minimum of 60 degrees Alt to achieve a more stable capture video. Less atmosphere at higher altitudes.
Most Planetary imaging video capture will bounce around a bit obviously the amount is dependant on atmospheric stability / conditions ( and your altitude)
The red slither or disc on the bottom and blue on the top is usually caused by imaging at low altitudes ( it’s an optical phenomenon or artefact )
I use Autostakkert to stack my video frames and Registax 6 to post process.
These have been around for a while now but work well.
Registax 6 will help remove those red and blue discs too.
Good luck with everything
Cheers
Martin
PS: I noticed the other night Saturn only just peaked around 65degrees Alt so that would have been the opportune time to capture it ( not down amongst the trees )
