Another barred spiral galaxy much like NGC1365.

From Wiki "NGC 1097 is a barred spiral galaxy about 45 million light-travel years away in the constellation Fornax. It was discovered by William Herschel on 9 October 1790.

NGC 1097 has a supermassive black hole at its center, which is 140 million times the mass of the Sun. Around the central black hole is a glowing ring of star-forming regions with a network of gas and dust that spirals from the ring to the black hole. An inflow of material toward the central bar of the galaxy causes new stars to be created in the ring. The ring is approximately 5,000 light-years in diameter, the spiral arms of the galaxy extend tens of thousands of light-years beyond the ring."

Capture details: GSO 10" F4 Newtonian, Baader MPCC MKIII, Pentax K-5 with just over 3 hours of subs of 30 and 45 seconds duration, HEQ5 Pro unguided.

Also good. The three bright stars to right add photographic interest.

Thanks M&T. Yes something else in the field makes for a break of the background.
