Pavo Galaxy

The Pavo Galaxy (NGC6744) is sometimes described as the galaxy most alike to our Milky Way. It lies about 30 million light-years away in Pavo, behind a carpet of foreground nearby stars. It's a fair bit bigger than the Milky Way at 175,000 light-years across compared to our 100,000, but has a pretty similar structure - many spiral arms and a central bar. We'd be about 2/3 of the way out towards the edge (an unregarded yellow sun in the unfashionable western spiral arm ). It's even got a disrupted satellite galaxy a little like our Large Magellanic Cloud - NGC6744A is a wisp of blue to the lower left.

Could do with a good bit more data, but this is 20 x 5 minutes (1hr 40min), and I don't know if I'll have time to get more. ISO800, EOS 60D, darks, flats and bias subtracted. 200mm f/5 Newtonian on HEQ5 pro mount, OAG & StarShoot Autoguider. Stacked and processed in PixInsight and Photoshop.
