Congratulations on this excellent venture… what a great idea!

I use WIKI 2 every day and almost forgot how the original Wikipedia looks like.

Structure
Sometimes called a "grand design", spiral galaxy, it is characterised by their prominent, well-defined arms, which circle outwards from a clear core (HST-image)
The morphological classification of NGC 5364 in the De Vaucouleurs system is SA(rs)bc pec,[4] 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).[5] In particular, the appearance of the spiral arms is amorphous and asymmetrical compared to other galaxies with a similar classification.[4] 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.[2]
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.[4] 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.[2] Each of the two main arms wrap all the way around the galaxy, although they display patchiness along much of their length.[5]
NGC designation
This object was discovered by William Herschel on February 2, 1786, and later listed as NGC 5364. It was subsequently rediscovered by John Herschel on April 7, 1828, and later listed as NGC 5317.[9]
