Previously I had taken a large integration on Sharpless SH 188 with the Ha filter in to capture the superb faint details this wonderful and delicate planetary nebula from the Sharpless catalogue of HII regions.
I also managed to capture 15x1200s of OIII via my 8nm Baader filter. This produced a very faint signal, however, I was able to combine it with the Ha data with a synthetic green channel to produce this colourised result
cCaptured in Maxim and processed in photoshop.
This image was autoguided using my homemade off axis guider with Lodestar.
