Integrated Flux Nebulae near M81/M82


David Elmore
 

Folks,

Here is a wide-field exploration of galactic cirrus aka integrated flux nebulae seen out of the plane of the galaxy. Thanks Dan for the pointer to the unexplored nebula project that includes this region.

Details: Borg 55FL 200mm F/3.6 astro-graph, ASI2400MC Pro (OSC), IDAS NGS1, 34 X 600 sec exposures. The NGS1 filter is broad band with pass band notches at wavelengths of high pressure sodium (not much use at DSNM) but also at the air glow oxygen emission band in the red.
Calibration, stacking and background removal in AstroPixelProcessor. Final color balance in MacOS Photos.

David,

Beautiful wide filed image. There sure is a lot of gunk out there in "empty"
space.
