      Description

      Messier 42 needs no preamble. It is around 1,400 light years away and about 24 light years across.

      This is a 4 panel mosaic that Barry and I did on our remote FSQ106 rig. Whilst M42 would have fitted within the FOV of the FSQ106 and KAF8300 combination, we wanted to set the nebula in a wider context. For various reasons, it took us some time to complete the project. We began on 11 January 2018 and did not finish until 13 January 2021.

      Technical details are as follows:

      Telescope: Takahashi FSQ 106

      Camera: QSI 683

      Filters: Astrodon

      Mount: 10 Micron GM1000HPS

      Ha: 72 x 1200s

      Lum: 120 x 300s

      Lum: 60 x 180s

      Lum: 120 x 30s

      Red: 96 x 300s

      Green: 96 x 300s

      Blue: 96 x 300s

      At the same time that we were finishing the Tak Orion project, we were shooting another (2 panel) project of M43 and Running Man using our TEC 140 rig. In revison D, I incorporated the data from the TEC project in an attempt to provide more resolution in the core.

      Telescope: TEC 140

      Camera: QSI 690

      Filters: Astrodon

      Mount: 10 Micron GM2000HPS

      Lum: 72 x 600s

      Lum: 24 x 60s

      Lum: 24 x 15s

      Red: 60 x 300s

      Green 60 x 300s

      Blue: 60 x 300s

      Total exposure time 89 hours and 30 minutes.
