Hello all...
2 good nights allowed some imaging of M17 to be done.
Canon 40D (modded)
Canon 300mm f4L IS @ 420mm FL (Hutech IDAS LPS2 filter for RGB)
HEQ5 Pro mount
Ha data 140mins (Astronomik 12nm Ha filter)
RGB data 90mins
All at iso1600
My favourite out of all of them is the Ha - starting to really enjoy narrowband work. Finding the HaRGB blending a bit dissapointing after seeing all the beautiful high contrast Ha data!
Cheers
Doug
