Description

Pushed the HEQ5 about as far as it can with 15minute subs, many of which weren't great in regard to star shapes, but still reasonably happy with the first steps in this direction and with what the ED80 is giving me. All very noisy but still collecting more data to help with this (I hope).

Pushed a bit harder for detail in the centre

Noise reduced and colored differently, but still needs about 10 times more data!
