Description

I've imaged this object before, but with my other (full frame), unmodded DSLR and the stock Alt/Az mount using 20-30s exposures.

This was the first time I attempted my MAK on the EQ6-R Pro with much longer, guided exposures. Imaged over two separate evenings, as the dark nights are getting shorter and shorter this far north (59N).

Lights:

21 x 180s @ ISO 1600

38 x 240s @ ISO 1600

Darks: 15 + 20

Flats: 15 + 20

Bias 35 + 35

In total, about 3,5 hours of total integration.
