IC 1871 Narrowband

[SamAndrew]

In stark contrast to Barry-Wilson's version earlier this week, here's my take on this nebula. 

Imaged over several nights during January through my Star 71 from my Bortle 7/8 back garden in London, this is 8 hours and 10 minutes in total.

• 3h10m Ha
• 2h30m SII
• 2h30m OIII

All in 5 minute subs at max gain. 

Feels like I've processed this 100 times as I've been accumulating the data; I've imaged the whole Soul nebula but the OIII data is still particularly noisy and suffers from a strong gradient even after several attempts at DBE in PI, so I've ended up cropping down to what you see here which I feel is quite striking. As the Ha data is the strongest I've used this as luminance to produce an HSHO image with some selective colour editing in Photoshop.

Feedback welcomed

Wow, v nice. I see you say you are using max gain. Is that 300>

Thanks, yes even at 300 the histogram isn't very far from the LHS, I can probably experiment with longer subs.
