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.

Data: Steve Milne & Barry Wilson

Processing: Steve Milne
