NGC7424 - a barred spiral in Grus

Data captured at the Qld Astrofest in 2013.

Scope: Ceravolo C300 @ f/9 = 2760mm FL, Atlas focuser
Mount: AP900
Camera: U16M
Filters: Astrodon E series Gen 2 LRGB
Guiding: Lodestar / MMOAG
Image scale: 0.67 arcsec/pixel
Exposures: 20x600s R, 13x600s G, 17x600s B, 44x600s Lum (15.66 hours)
Processing: PixInsight

High res at Astrobin (don't forget to click the full res icon if you feel like pixel-peeping): http://www.astrobin.com/full/229132/0/

This is a repro and a nice improvement over my original 2013 version. If I could go back in time I would slap myself for only taking 600s subs.

Constructive comments appreciated, of course!

Cheers,
Rick.
