Dû_1..the most recent PN

[paulobao]

Hi,

At the 18th of this month, french amateur astronomer Pascal discovered a planetary nebula while photographing a sh object. What a great moment that should have been .

Today I manage to find about 2 and a half hours without many clouds (from 21h30 to midnight) to get some data of Dû_1. And yes it there! it is like the soap bubble nebula in cygnus but much more weak!

So, congratulations to Pascal for this discover

Tak FS102NSV @ f/6.2 + QSI 532WS-M1 @ -15ºC

Ha: 120 min only (no much stretch possible)

Cheers,

Your work never ceases to astound me

Thanks Mick.

And after a search at SIMBAD/CDS....just right to it there is (photographicaly speaking) another one the PN G094.5-00.8 !

This is really "cool" and I'm asking...why they did not saw it before?

Here the photo with both locations:

As a PS, I would like to add that the name of the discoverer is Pascal Le Dû...so the name of the PN (Dû_1). As someone said, no I have the full Dû catalogue :-).

Cheers,

paulo

Paolo do you have the RA and Dec for this object?

Amazing, still shows even well imaged areas you can find new things. I suppose it was missed because of all the rest of the surrounding nebulosity and people thinking it was just part of that and not looking closer.

I would never have thought it was not part of the SH nebula!

[prokyon]

Awesome!

I would never have thought it was not part of the SH nebula!

It's an amazing find and congratulations to Pascal Le Dû for the hard work that he's put into this - but...

Excuse my ignorance but how do you know that is isn't part of the SH nebula?

Cheers

I believe they are still waiting for a spectra to confirm it is a PN. The diffuse Sharpless nebula will have a different spectrum from a true PN.
