Description

With my backfocus pretty well sorted on the .74 focal reducer for the Stellarvue SVX080T-3SV, I though I'd finish the night with some subs on this, the most photographed of DSOs.

The low ISO, (200), short exposure, (180 second), approach seems to be delivering on minimizing star bloat and giving better dynamic range I think.
