M97 in Ha (April 8, 2014)

This planetary nebula in Ursa Major is one of the few popular narrowband targets up during the spring.  It's a bright one, too.  This is only H-alpha.  I hope to get the OIII, too, and combine them.  But the night I set up to collect the OIII data became unexpectedly cloudy at 11 pm.  Oh, well.  In the meantime, M97 is slipping behind my trees.  I may have to wait till next year.  Either way, the data interests me.

This data is 8x1200" with the 6nm Proti Astronomik Ha filter and 10x900" with the 12nm Astronomik Ha filter.  The dimmest stars in the image are below magnitude 19.

Camera and Exposure: SXVF-H9 (8x1200" with the 6nm Proti Astronomik Ha filter and 10x900" with the 12nm Astronomik Ha filter), Alnitak Flatman flats

Thanks, Rory! For some reason the Newt was working that night.
