Description

Another processing, with attention to Trapezium area.

I am testing again my 350D without IR filter. After the adjust of focus in both cameras, Canon and guinding, M 42 was in good position.

Attention for low time of exposition for a Canon camera:

RGB 6 x 1 min ISO 400 Skyglow filter

Halfa 10 x 3 min ISO 400
