Here's a heavily cropped image of a number of NGCs in Ha (the second image has been annotated for them). I find it interesting that the feature between NGC2040 and NGC2053 doesn't seem to have a "name".
Image Details:
Sharpstar 107PH with 0.67 FR (f4.4)
ZWO ASI1600MM-C at -15C
41 x 300 sec Ha at Gain 139, offset 21
40 Darks
Processed in PixInsight
211290
211291

It's a bit noisy to me, so I think I'd like to get more data to hopefully enhance it further - especially around NGC2014/2020. I've also got some SII as well and eventually would like to get OIII. I suspect the Ha is going to heavily dominate though as the SII is faint.
As usual CC/feedback etc welcome. P.S. Yes, it has some of those terrible stars as mentioned in this thread: http://www.iceinspace.com.au/forum/showthread.php?t=154850 :)
