Description

Markarian's Chain, a wonderful cluster of galaxies in Virgo.

This image was captured using the IDAS LPS-P2 light pollution filter. I imaged this same target a week ago using UV/IR cut only, and was not as impressed with the exposure length due to surrounding light pollution. With around the same amount of integration, I was able to pull more details out due to longer exposures.
