M42 HaRGB

[carastro]

I added some Ha to the OSC data I took earlier this month.

Previously taken RGB QHY8L 1 hour 40mins on ED80

and now 2 1/2 hours Ha Baader 7nm Atik383L cooled to - 10degrees on ED120 (should have used ED80)

Guided with finderguider on NEQ6

of which I did 900sec x 7, 300sec x 8 and 30sec x 6

Hi Carole - nice image - there's certainly more detail visible with the added Ha. I don't know if it's my eyes, but does the focus need a tweek?
