Pu-We 1 (Purgatofer-Weinberger 1), PN in Lynx, two versions

[Fegato]

I spotted this as a good target for later on in the night at this time of year. It's a very large PN at around 20' diameter, and one of the closest to us at around 1200 light years. It is faint though, and was only discovered from the Palomar Survey plates in 1980. Current equipment makes it very accessible though.

I also found that I had 48 minutes of exposures from two years ago, which I had totally forgotten about. Lots was added to this with the NBZ filter, totalling 7h 15', which I think is as much as I've ever shot on one panel. I also took about 50' worth of broadband exposures for the stars. Of course when processed, as ever with the RASA, a dusty backdrop appeared.  So here are two versions, one close-up - narrowband with RGB stars, and one wide field - broadband with enhanced narrowband for the PN.  

I've also attached an annotated version which highlights the various PGC galaxies as well Quasars from the "Million Quasars" catalog. I hadn't realised this had appeared in Pixinsight, and it's a bit of fun trawling around and looking these up. Only looked at a few, but the first couple I looked up were estimated at 8 and 10 billion light years distant!

Very nice, I like the close up version best 👍

[Fegato]

Thanks Dave, yes I think the other one needs a bit more contrast - a bit washed out I think.

[Roy Foreman]

Yes the close up version looks great. One to put on my to do list. Nice work.

Superb, never seen or even heard of this one.

Great image, not heard of this one before either. The same apparent size as the full Moon on some reports. It's well north so should be viewable for most of the year. 🙂

Both are excellent Robin.  I really like the wider version with the dust.  You mention a bit washed out but only in comparison to the tighter crop, the compromise is a super back drop for the main object.

Absolutely lovely images of an object I had never heard of. Might well try that at some time
