That's an improvement, from what I have seen the light pollution filters tend to intensify the ha colors from a magenta to a red. With the encroachment of city lights here I may end up using some form of light pollution filter.
Still a bit salmon but nice all the same. Great field of view. I have a 300 f2.8 and I might have to take a look at this myself at some point. Always a credit to you to hand guiding each image. It would bore me silly and it was painfull when I was doing it with film in the 80's. Well done.
Thanks all. Mind you I have to guide continiously for only 10 mins at a time, though normally when everything is going smoothly I keep guiding, just reaching over to terminate each exposure and start the next every 10 mins
