Messier 1 Re-Re-visited

[Hughsie]

Messier 1, Crab Nebula. 

I have been photographing this supernova remnant during the clear nights available to me in January. This image is based on the Hubble Palette and uses Sulphur, Oxygen and Hydrogen filters (Sii/Oiii/Ha) to create this pseudo colour picture.

Each image of which there are 85 is made up of 5 minute exposures;

Sii 25 x 5 mins        (Baader 8nm 1.25”)
Ha 30 x 5 mins       (Baader 7nm 1.25”)
Oiii 30 x 5 mins      (Baader 8.5nm 1.25”)

Sii/Ha (Gain 139 Offset 21); Oiii (Gain 75 Offset 15)

These images were then calibrated and stacked using the software, Pixinsight.

Time to move on to another target now though I will be returning to M1 next year to capture some more data.
