    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.
