The extended halo of NGC 253

NGC253 captured over two nights last weekend at the AAQ Dark Sky Observing weekend at Glen Aplin (props to John Salini for being such a gracious host!)

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: 7x900s R, 7x900s G, 7x900s B, 30x600s Lum (10+ hours)

Inspired by Mike Sidonio's attempts to show the extended halo of NGC 253 I have attempted to do this too. Not sure if the experiment has been entirely successful but you have to try these things. Unfortunately, my FOV is too small to include the Peter Ward S-bend

Constructive criticism appreciated...

Thanks,
