Setup #1:

  • Takahashi FSQ-106ED w. Reducer QE 0.73x

  • USB_Focus focuser
  • Starlight Xpress Filter Wheel 7x1.25" w. Astrodon 3nm Ha/O3/S2 + LRGB
  • SX-OAG w. Lodestar

Setup #2:

Setup completed

Today I finally received the last two missing narrowband filters in my filter wheel: Astrodon 3nm O-III and S-II arrived. This seven position wheel now has got Ha, O3, S2 and LRGB filters mounted.
