Crab, 25 Hrs.

[ollypenrice]

This was done with the productive dual TEC140 rig co-owned by myself, Tom O'Donoghue and Mr and Mrs Gnomus. (Atik 460 and Moravian 8300 on Mesu 200 mount.)

RGB 3 hrs per colour. Ha 8.25 hrs. OIII 7.75 Hrs. Stacked in Astro Art, components aligned and resized in Registar, post-processing initially in PI but mostly PsCS3. Ha to red, OIII to green and blue all in blend mode lighten with the green/blue balance done in Ps Layers. An Ha-OIII monochrome blend was very lightly applied as luminance as well.

Let's spare a though for two people, here: Fritz Zwicky who had the intellectual courage to realize that nature could create neutron stars and Heather Couper, with whom I overlapped at university without ever meeting her, and who died recently. She was a great communicator of astronomical science.

For those who like more 'pop' here's a version with higher contrast.
