Al Ernst's image of NGC 1491, located in Perseus

NGC-1491 is a faint emission nebula approximately 11,000 ly from Earth. This image was taken in late November from Al's Bridgewater, NJ observatory, using a C-14/f7.7 telescope, a QSI-583 camera and narrowband Ha and Oiii filters, with one hour of 5-minute subs in each band.  Processing was in Nebulosity and Photoshop.

Thanks for the submission Al,

Keith
