I had some trouble processing this one. There are faint jets emanating from the galaxy and getting these to show up without blowing out the galaxy was tricky.
Taken over the last new moon period.

Description:
NGC 1097 is a Seyfert galaxy, harbouring a supermassive black hole in its centre. There are four mysterious jets in an X shape centred on the nucleus. Two of these pointing to the upper right corner of the image are easily seen here. The upper one has a right angle bend and is often referred to as the "Dogleg". There is a faint suggestion of a third jet to the left of the image opposite the fainter one on the right. This is readily seen in the inverted view.
