It's not going to win any beauty contests but here it is - click for 988x900 image, cropped from full frame:

Scope:Pentax 105mm SDP, with 2x power mate 1370mm fl

Camera: 383L+ (0.88 arc sec/pixel image @ 1370mm)

Subs: 8x300 sec mono, no darks, no flats

Mount EQ6 with 16ic guiding through

Processing: 4x4 upacale drizzle, then dynamic PSF deconvolution as described here: http://stargazerslou...d-some-clarity/

Also spot the guider failure.. the guider star was out of focus but gave a good lock on - note the divergence over time (earliest at the left, last sub towards the right):

Additional processing - removing the motion blur (elongated stars) and second dynamic PSF application:

I think I'm happy with that. Only adding more subs and time (+colour) with more accurate tracking would result in more.

Not bad from this (the best graded sub of the 8 used, at native resolution):

Very nice & you can see the central star

Good start

Excellent image recovery with that processing.

PI on Chrismas list.. boy that list is getting long!
