North America Nebula HaRGB - a photo on Flickriver

            Another clear night last night, and just enough time to do 6 x 1200 seconds Ha on NGC 7000, The North America Nebula. 

Using the RGB image I did in 2013, I added 30% of the Ha to the comparatively weak red channel, and then used the Ha again as luminance, for this result. I may add some Olll when there is more dark about :)

RGB:
SW ED80/EQ5
Canon 500D modded, Baader Neodymium filter
35 x 300 sec subs, iso 800

Ha:
ED80 with 0.85 focal reducer
HEQ5 Pro, belt driven
Cooled mono Canon 450D, Astronomik 12nm Ha filter
6 x 1200 seconds, iso 1600
