Alnitak interference pattern - 8" f6 Newt.

Hi guys,
I was re-processing my Flame & Horsehead Mosaic pic last night
when I came across some shorter sub frames I'd taken.
I also re-processed the RGB just for Alnitak with
a linear stretch out of the stacks to work on.

I got a wonderful interference pattern that looks like
twisted rope on the mono frames & comes out very nicely in colour.

I used a 25 second exposure frame of Ha to get the smallest
star size - which was not reaching the well depth - & used it for the
center of the boosted colour shot.

I believe that the star near Alnitak it's one of it's companions?

I include a tiny re-process mosaic of the Flame & Horsehead where I tried to use
the Alnitak rainbow spikes - the re-process was much better
but the spikes were hard to put in with all the colour here.

All comments welcome.

cheers
