Gina's NB widefield dual rig


Recommended Posts

  • 2 weeks later...

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.
