ARP 273 - Rose Galaxy

Arp 273, a.k.a. The Rose Galaxy is a pair of interacting galaxies located approximately 300 million light-years away in Andromeda. The galaxy on the top goes by UGC 1810 and is reportedly 5-times more massive than UGC 1813, the smaller galaxy. Both galaxies have a yellow core and blue heavily distorted arms. UGC 1813 has new star formation in the core whereas star formation in UGC 1810 is concentrated in the outer arms. The extraordinary interactions between these two galaxies is suspected to be the cause of the recent star birth, in fact it is believed that UGC 1813 passed through UGC 1810.

The bigger, the better for this object! The image seems to be widefield but I cropped it quite a bit already which indicates the Edge800 is near the lower size limit. I was happy with how the detail came out and a big part of that was BlurXTereminator (BTX). Everyone has been saying this is a "Gamechanger" and for the first time I agree. Unlike other sharpening programs that do sharpen well, the problem is they sharpen everything including noise so you have to do a lot of masking and creative blending, BTX sharpens the object but not the noise. Lastly, I really like the background as it is rich in colorful Milky Way stars and small galaxies.
