So many questions. Don't know where to start?!? What focal length are these imaging at? From what I can see they are the same. Are you reducing time by using two different filters concurrently? And what pushed you to go down this route?

@Gina

Could you give us some more information about this setup, and maybe an picture of the front side?

Current rig has 200mm f4 lenses used at full aperture.  These are Asahi (Pentax) Super Takumar lenses.  I image with two different filters at a time.  One camera has a filter wheel where I have an Ha and an SII filter.  The other camera has an OIII filter.  All filters are Astrodon 1.25" mounted and 3nm bandwidth.  The lenses have remote focussing.  Cameras are ASI1600MM-Cool.  There  is also a guiding system with ASI178MM camera and 200mm lens.  The box on the end contains electronics.  Each imaging system uses a Raspberry Pi for capture and control.  These also control the focussing of the lenses.  Software is INDI (server and drivers) on the RPi and KStars/Ekos on my computer indoors.
