Motch-Werner-Pakull 1 and, serendipitously, Alves 1

[Herbert West]

Motch-Werner-Pakull 1 - I've been planning this one since last year.

I judged my FOV to not be wide enough to reasonably include the nearby Alves 1 and decided to ignore it in favor of placing the main target in the center. Framing and rotation were done semi-blindly, looking at asterisms, because there's next to no trace of MWP 1 even on 300s subs. However, after stacking data from the first (of many) nights- lo and behold! - Alves 1 was in the corner. I just couldn't crop it out, even if it resulted in wacky framing. Sorry, but not sorry :-)

That slight brightening on the right edge isn't an artifact, by the way. There's a fairly bright, elongated OIII structure there and I've managed to just clip its periphery.

 

Pretty picture:

Wow, that's a new one for me.  Looks very interesting.  Great work and thanks for sharing

Thank you, Martin. It's less known than it should be. As far as dim, large and unusual PNs go, this one isn't among the most difficult. It's fairly bright in OIII, where all the details are. One could get away with ~ 25 hours of exposures with medium f ratio under good sky and get a decent image.
