I took a series of short exposures the night I compiled the Orions Sword image with the intention to use it for adding detail in the bright regions at the core of the nebula, in the end I didn't use it but here I have combined it any way for a bit of interest and to reveal the fine details in and around the Trapezium. I didn't take any good RGB data so it is presented as L+ Ha only.
The image is only about 4' X 4' square so this will give you an idea of the resolution - you can see the proplid proto stars made famous by Hubble in and around the main trapezium stars - bah, who needs long focal length?
Normally, I'm an advocate of the long focal length... I have to say I'm really really impressed to see the trap so well defined... is that trap E, F AND G that I can see in there? Pretty amazing for a measly 6" F/7.5..
I know I tried it (all be it with poor collimation and average seeing) with my ST9E + C11 @ F/10... got A, B, C and D split, but no sign of E or F...
