Finally another image with my recently acquired 130mm f5 imaging "optimised" baby newtonian, mounted on a HEQ5. Camera was a modded 1000D, guiding using a QHY5LII with a Rubinar 500mm f8 mirror lens as a guidescope.
Capture details (all ISO1600):
"Inner" core: 58 x 10sec, 36 x 20secs
"Outer" core: 52 x 60secs
Rest of image: 42 x 120secs, 31 x 180secs, 70 x 240secs
Hi-res:
