Cheers Mike. The previously posted image wasn't meant to be visually pleasing, just thought I'd post it.

Anyway, here is a version that I spent some more time processing.

Processed in MaximDL/CCD 4.5 - PS CS2:
Recalibrated with DF. Non-linear stretch with no DDP to obtain initial levels. Removed 100 pedestal value to avoid clipping. 2 deconvolution runs of L-R method. Final curve adjustments. Saved from FIT to TIFF16. Loaded into PS, set white output balance to 200 to avoid white point clipping introduced in next step. Full unsharp mask - Amount 40% - pixels 250. Re-adjusted levels. Minor unsharp masks around key features - amount 10% - pixels 50.

Didn't want to over use the unsharp mask. Its tempting, but I like images to look natural and not heavily processed. More data is required for this object - 80 minutes is too short for a luminance channel in my opinion. Still processed on a laptop. LOL
