Description

I'm very happy with this new shot of Thor's Helmet! Ever since I found out about this object I thought it was a very cool target and my previous attempt from a couple of years ago really didn't do it justice, but I thought the new 6-inch refractor would be just the thing so last fall I had another go.
For some reason PixInsight kept 'cacking' on the data and would crash at the exact same point while crunching the H-Alpha data and in an act of desperation I reduced the number of subs from 50 to 17 and it finally finished! 
So this image is six months in the making! 
Pixinsight is amazing, but when things go wrong it sure is a devil to figure out what happened!
