I'll say this Marc...
I use 30sec subs through a 7nm Ha filter to frame the image... I dont see nebulosity, but I can just make out the star cluster to the top left of the pillars... I run 20min subs to get nebula extension that you've captured there.. my scope is 80mm F/6... So clearly, 80mm F/6 gathers less light than 280mm F/2

hahah!
Ps - M16 looks Sahweeeettt!!
Stomach.... Turning.... Soooooooo..... Jealous....
