Supernova in M101, Aug 25th, full processing

August 26, 2011

It’s about a total 3 hr exposure with a 11in CPC1100, using a canon 60d (iso 2500).  30s exposures,  throwing away bad exposures (about 60 %) to yield this using deepskystacker (using about 50 dark frames).  The arrow indicates the supernova.

Supernova in M101, August 25th 2011, about a 3 hr exposure with an 11in scope and 2500 iso on a canon D60.

Clearly an improvement of the first attempt which only included about 12 minutes of ‘sky time.’

Right, now back off to the pass to do the same thing again tonight! Me= CRAZY! :-p

First look at Supernova in M101 (Aug 2011)

So after much driving around looking for a good observing sight I eventually found one north of Klamath Falls Oregon (good clear view north).

(‘Klamath Falls’ astronomy site, 25th August 2011)

I then brave the moquitoes, and yeah, there were a LOT of them, to get the scope set up.

The scope acquired data for several hours, this is thus far only processed from 6 minutes worth.  I’ve also not got round to sorting the colors out which is why the new exposure appear blue compared to the old one.
