Notes:
Hickson 44 are multiple (four seen here) interacting galaxy group. Due to their gravitational interaction, galaxies are distorted and perhaps will merge in the future. Due to their interaction, there is intense star formation going on in these galaxies.
Originally, the elliptical galaxy NGC 3193 was considered as a part of Hickson 44. However, latest spectroscopic studies put its membership as a question mark.https://arxiv.org/pdf/1609.00224.pdf
Imaging Notes:
This image was one of our first images with the new set up with F3.8 10” Newtonian. The scope with corrector, focuser and camera do push the limits of MyT. However the set up performed extremely well during the imaging at Calstar.
One can spot about 15+ galaxies in the image as this area is rife with background galaxies.
