Object name: NGC5448
NGC 5448 is an interesting spiral in the southeast corner of Ursa Major. Redshift puts it 100 million light-years distant though Tully-Fisher measurements average out to about 120 million light-years. A rather good agreement actually. Assuming the 100 million light-year distance it is about 120,000 light-years in diameter making it a rather large spiral. NED classifies it as (R)SAB(r)a with and having an AGN (Active Galactic Nucleus). The NGC Project disagrees say simply it is SBb. It has a faint outer disk beyond a bright ring-like feature created by its spiral arms that nearly overlap. To my eye, the outer disk appears warped. That may be an illusion. It was much stronger in the FITS files than when processed with color added. No papers on it that I found mentions any warp so it likely is an illusion I can't shake. It also has some strange dark lanes across the disk inside the ring on the south side. Looks like a tot drew them in with a crayon. It was discovered by William Herschel on May 15, 1787. It is in the second H400 program.
