Wow, wow, wow. For me the pick of the 3 fantastic photos I've seen so far. I didn't expect to see anything better than had already been posted. I believe it partly came from the passion you have for this part of space.
I always preferred a 2012 picture published by APOD to many others I've seen, only my irrelevant personal choice so's not to offend anyone, anyway this improves upon it so much. A lens available used at under £1,000!
I hope maybe you'd submit it to a magazine, but if it came to an award in a competition I fear it would unjustly lose out due to the new style of judging. I'm just an old, sorry really old fuddy duddy that is impressed by the skills in processing these wonderful objects in space. Seeing the same object replicated umpteen times in different colours is skilful but not something that actually exists. Partly my reason for cancelling a subscription. Must stop my rant now.
Rare for you to post anything Peter, how about a few more. They don't have to be quite the same standard.
Best regards, Ray
Nearly forgot. Many thanks for your reply to my questions on camera gain. Good explanation and I'll act on it accordingly.
