The BH is said to be 1 billion solar masses so diameter ~ 39.48 au. The arXiv paper link https://arxiv.org/pdf/2106.05340.pdf, reports: "IC 4296 is at heliocentric redshift z = 0.01247 ± 0.00003 (Smith et al. 2000)...Velocity-independent angular-size distances have been estimated from surface-brightness fluctuations of IC 4296 by Lauer et al. (1998) (DA = 49.4 Mpc) and by Mei et al. (2000) (DA = 49 Mpc). For simplicity we adopt the comoving distance DC = DA(1+z) = 50 Mpc so 1" = 240 pc and 1' = 14.4 kpc."

So we have some geeky stuff in the paper 50 Mpc distance ~ 163 million light years distance. The paper states in the abstract, "The nearby elliptical galaxy IC 4296 has produced a large (510 kpc) low-luminosity radio source
with typical FR i core/jet/lobe morphology."

510 kpc is very large size, more than 1.6 million light years. The angular size on the sky is larger than 0.5 degrees across as reported for the image. "The Fanaroff-Riley Type I radio galaxy IC 4296 dominates this spectacular vista, wider than the full moon on the sky."

Those are some geeky stats here
