Description

Ngc 2276 is an asymmetric spiral galaxy in Cepheus, located at a distance of approximately 120 millino lightyears. The asymmetry in its structure is most likely caused by gravitational interactions with its close neighbour, elliptical galaxy ngc 2300. Ngc 2276 is only about half the size of ngc 2300.Processing was done in PixInsight. To get more detail in the structure of ngc 2276, I drizzled a small crop of the L data and used deconvolution and Multiscale Median Transform before inserting it back in the undrizzled larger view. After this I did normal LRGB processing. There is the slightest hint of IFN in this image, just left of this galaxy pair, but I didn't push it in processing.
