Thanks for posting up the avi Steve. Here's a go using Registax 5.1, 947 frames, RGB align, Astra Image with Lucy Richardson Deconvolution PSF Size 10.00, Wing Adjustment 3.08, 10 Iterations (Aggressive), then Unsharp Mask in PS with Levels (eye dropper on the pole to correct white balance) and resampled up a bit. You got some nice detail in your capture
Also added a WinJUPOS animation of your image.
Cheers,
Tom
