Description

This was captured with over a month and a half of data in a heavily light polluted red zone 15 minutes outside of Detroit. I tried my best to pull out the data.

NGC 5364 is a grand design spiral galaxy located 54.5 million light years away in the constellation Virgo. It is inclined to the line of sight from the Earth at an angle of 47° along a position angle of 25°.

The morphological classification of NGC 5364 in the De Vaucouleurs system is SA(rs)bc pec, which indicates it has an incomplete ring structure (rs) in the inner part of the galaxy with moderate to loosely wound arms (bc) and has a peculiar aspect (pec). In particular, the appearance of the spiral arms is amorphous and asymmetrical compared to other galaxies with a similar classification. A companion galaxy, NGC 5363, is located to the north of NGC 5364 and their gravitational interaction may be influencing the peculiar morphology of the latter.

The mid-infrared emission in the nucleus appears weak compared to the spiral arms, suggesting a low rate of star formation in the core region. The inner ring of this galaxy spans a diameter of 22 kly (6.7 kpc) and is located slightly off center with the northern side showing a stronger emission in the hydrogen alpha band compared to the southern half. Multiple H II regions lie along the spiral arms, tracing out their extent. Each of the two main arms wrap all the way around the galaxy, although they display patchiness along much of their length.
