Description

Predominately yellow, with sweeping spiral arms and dust lanes, NGC 5566 is enormous, about 150,000 light-years across. Just below it lies small, blue NGC 5569. Near center, the third galaxy, NGC 5560, is multicolored and apparently stretched and distorted by its interaction with NGC 5566. The galaxy trio is also included in Halton Arp's 1966 Atlas of Peculiar Galaxies as Arp 286.

This is a small target for me, the field of view is about 30 arcmin, and the major axis of the largest galaxy is 5 arc min. 

I tried a new technique for this one, twice the number of exposures and half the exposure time. The advantages are that with so many frames, I really didn't need to use any calibration frames, everything was cleaned up by the stacking rejection algorithm. Also, my average eccentricity was lower. The disadvantage is that processing so many large files takes half of forever.
