taken over three weekends using a Proline 39000M camera mounted to a 6x7
format pentax 300mm f/4 EDIF lens
all subexposures were 15 minutes and there were a total of 146 of them for a
total of 36.5 hours
I took 88 exposures of 15 minutes of sulfur, 22 hours total in sulfur
the Halpha was 3 hours, the rest was oxygen

I've been at this for a while so I am going to call it finished and move on
to something else next weekend.
notice in the full resolution version that there is a smattering of PNe in
the upper part of the image and a few elsewhere
also at the bottom center right above the edge is a Supernova Remnant,
