Celestron C14 Edge HD @ f=6650 mm (F/20), res = 0.13"/px
+ Celestron CGE Pro mount
+ Celestron EF
+ ZWO ASI 290 MM
+ Baader 2x VIP Barlow
+ ZWO EFW
+ Baader IR (685 nm) filter
+ Tempest Cooler
+ Omegon Dew Heater
+ Astrozap Dew Shield for C 14

Very short imaging train: I simply screwed the Baader VIP Barlow into the nose piece of the ZWO EFW. However, the small pixel size of the ZWO ASI 290 MM leads to a pixel scale of 0.13"/px at a reasonable f-ratio of f/20.

IR: 12 x SER movies
~6200 frames/movie
19 ms exposure time, gain = 368
1x1 bin

recorded with Firecapture

Saturn 30° above the horizon
Seeing: Pickering 4-5 (poor)
