Description

OU4 is a very difficult target to get with a light setup, ... but I try, but I try, but I try, try, try ! 
Well, during several clear nights around sept. 7th, I coud acquire about 17h of exposures with my QHY163M like that:

For nebulas, Samyang 85mmF1.4 (diaph. 2) :
OIII : 94 x 300"
Ha : 30 x 300"
SiII : 58 x 300"

For stars, Samyang 85mmF1.4 (diaph. 8 ) :
R : 30 x 60"
G : 30 x 60"
B : 30 x 60"

I chose for a first version a SHO treatment with standard hubble palet.
