The Heart Nebula IC 1805 H-Alpha

Description

IC1805 most commonly known as The Heart Nebula lies some 7500 light years away from us and is located in the constellation Cassiopeia. This is an emission nebula showing glowing gas and dark dust lanes. This nebula is formed by the plasma of ionized hydrogen and free electrons.

Here it was shot using a 3nm H-Alpha filter, unfortunately it doesn't quite fit as I would like using the native focal length of the TMB92SS, at the moment I'm still testing various focal reducers to overcome this problem.



Total Exposure 5.5 hours
