Had a go but need short exposures to do the trapezium justice, as well there are a few colour gradients which were hard to remove.
Anyway here is mine for what its worth.
Only just came across this white rabbit and tempted to play with tiff data ? so thought to throw my result into the mix ? Thanx for the experience , I have not nothing to use for sometime, weather & all !
Thanks for sharing your data White Rabbit, I had a go at it when you first posted your thread but I haven't had the chance to post my version till now, sorry for taking so long.
Anyway here's my attempt.
Hi WR. Had a go at this too. Tried to keep the colours authentic, with no attempt to remove the red dusty areas which is typical of this region - it's a ruddy, dirty region of the sky. Probably needs a set of longer exposures to fill these areas in. Some shorter exposures to reveal the core would make it a fabulous image.
