Description

Expectations were high for this picture, since the sky had been cleared by a heavy wind throughout the day, which had finally subsided at night.
Also two hours of integration with the sensitive 183MM camera looked enough to reveal many details of the nebula.
Possibly expectations were too high and hence the final result created some disappointment.
I cannot deny I would indeed have expected something better, but it is also true that the 72 mm F& APO is way slower than the Samyang lens with which I imaged the same subject a few nights before.
A focal reduer for the 72/432 may be my next purchase.
