MarkS Posted May 24, 2015 Report Share Posted May 24, 2015 (edited) This one shot 17th May from my dark sky site north of Melbourne. M83 (NGC5236) is commonly known as the Southern Pinwheel galaxy. It is about 15Mly away in Hydra, and is about 40 kly across. It is a starburst galaxy, with many red and blue supergiants, a high rate of star formation, and 60 known supernova remnants. It's radio centere is displaced from its optical centre. This is thought to be possibly due to the cannibalisation of a smaller galaxy. ASA10N in f/6.8 configuration; DDM60; STT8300M RGB only; total exposure 4 hours. A fairly good night - best SQL 21.15. A lot of moisture in the air. Mark Incidentally, with the latest AS and Sequence beta versions I think AF has improved.. Edited May 24, 2015 by MarkS Link to comment Share on other sites More sharing options...
