SN1987a attempt

Inspired by Rolf's incredible webcam effort, I tried this
morning to see how well I could resolve his star grouping
in the outer Tarantula Neb/LMC . This is with similar size pixels and
the DSI II cooled to 10 C from 33 C ambient. 12" Newt at 1524mm f.l.

I think this section of the neb has been called the Honeycomb
Nebula and my first image has been processed to emphasise the
nebulosity. Seeing wasn't the best.
The second is a crop of the SN1987a region with a curve and sharpen
to best resolve and separate the blobby stars.

I think for me it's a no go...I can't say for sure that I have picked up any
faint evidence of SN origin.
