[5] In the centre of the galaxy lies a supermassive black hole whose mass is estimated to be (10.6±4.9)×106 M☉ based on the spiral arm pitch angle.

[5] Straight dust lanes are observed along the bar, the one smooth and the other appearing broken.

At the end of the bar the spiral arms form a pseudoring with diameter of 71 arcseconds.

[8] Based on observations in far ultraviolet (FUV) and Hα there is active star formation at the pseudoring.

[9] Based on the B-I color profile of the galaxy the bar finishes at 23 arcseconds, at the same distance where there is a population of older stars, and thus is suggested to be the corotation radius of NGC 7723.
