This was an experimental handful of frames at M27 with the astronomik CLS filter. I could have gone longer, but my patience was wearing thin and I had to get up for work in the morning. Processing the frames and stretching violently gives a hint in the noise of the outer halo of M27. A slightly less noisey image of this feature can be found here. This image shows some potential. A longer, more dedicated set of frames could get something approaching a presentable approach. Or I just get that set of emission line filters! ;-)

Captured in k3cddtools, stacked in registax, curves and histrogram in photoshop. 50% faded with darken minimum filter on selected highlights
