Here's my last one from my summer crop - it actually turned into a year-long project, I took the Ha in August 2017, the OIII in July this year and the SII in August.
10 each x900s Ha, OIII and SII, darks flats and bias, equipment as per sig, taken in southern Spain, PI processing.
Just for fun, here's a side-by-side comparison of my Pillars of Creation vs Nasa's, can you guess which is which ?
Ok, not much of a contest really, but then their telescope is a bit more expensive than mine is ! Quite interesting to have a close look though, there are a number of features in common that I have managed to pick up that aren't apparent at first glance.
I'd be happy to receive feedback on what you think, feel free to be honest since I'm not quite sure how I feel about it, especially the colours. Comments and cc welcome.
Hope you enjoy,

Another M27, this time with H-alpha added: I set out to capture the outer shell, no matter how little or much. It may not be perfect, but I'm happy with it. 2x15min, 2x10min, 31x5min, RGB 5x5 in each channel, bin x1, altogether 4:40h of exposure. This is an HaRGB image, Ha integrated into red, and the separate HaR used as luminance.
