Image Information:  NGC 2276 is an asymmetrical spiral galaxy located approximately 120 million light-years away in the constellation Cepheus.  Its distorted, lopsided shape is believed to be the result of a gravitational "tug of war" with its neighbor, the elliptical galaxy NGC 2300.

Processing Information: These Ha/SII/OIII + RGB images were obtained using AstroDon filters.  The Ha/SII/OIII + RGBB images were batch processed (calibrated, registered, normalized and integrated) in PixInsignt.   Further stretching, high pass filtering and background smoothing was performed with Adobe Photoshop CS/4 and PixInsight.
