Description

M38 Ha + LRGB

The luminance with LPS filter and H-Alpha is from ts apo with focal lenght of 420

The colours are from dslr 600d with short exposures of 1 minute on apo with focal lenght of 700

The contribute of the sensibility of atik 460exm is very important

The field of the atik 460exm on 420 focal and the field of dslr on 700 focal lenght is the same (little difference)

The H-Alpha (little, only 40 minutes) help me to capture the nebulosity around this open cluster

The spikes are artificial

Ha 4 x 10 minutes

L 15 x 3 minutes

RGB 30 x 1 minute
