3 Ha shots

[Erwin Kats]

last week there were 2 clear nights, i wanted to get some HA,L,R,G,B data so i can try editing HALRGB pictures... but i did more Ha shots because of my short focal length.

my asa ddm 85 is not on the pier at the moment because of some testing

so i am happy that i did not sell my losmandy g-11 yet, and put my qsi 583 WS with canon 70-200 2.8 IS on it on 200mm f5,6 and baader 7nm Ha filter

all shots the chip was -30

i think the gradients are caused by a new sky beamer of our local government :)

a bit of pixinsight or gradx will sort out the gradient for you

I think the monkey head is my fave, not seen a widefield image of it, it gives it another dimension .
