Image data aquired on 7th-9th Sep 2014 from my suburban back garden in Macclesfield UK.
Taken under the poor conditions of full Harvest Moon this was a good test of my new 3nM narrow band filters. I particularly like the colours and contrast these filters produce, the teal blue OIII really stands out. The Pacman nebula contains some very interesting small dark inclusions (Bok globules) which are clouds of dust and gas being eroded by intense radiation from nearby large stars. I also like the apparent 3-D look produced by the stark black foreground clouds and the fainter clouds in the background which make it appear as if we are viewing inside a sphere of hot gas, which I guess effectively we are.
