Hi everyone,

I was looking around through the Finkbeiner survey on Telescopius and I found a rather strange, faint region of Ha (image below). It appears to be in the constellation of Aquarius, roughly centered on Ra: 22 hr 25' 30" Dec: 01º 24' 07". After a fairly extensive search, I wasn't able to find any info on it. So, does anyone have any idea what this object is? Thanks in advance for any ideas.

Clear skies,

The0s

A couple of links:

Your exact location (seems to be off from where I see it in Aladin though).

Where I see it in Aladin

It's not much to go on though, here's the screenshot I grabbed from Aladin:


Same one in inverted Red channel:

I saw it before, unfortunately it's placed in an area of sky where I can't image, also unfortunately, this thing is so large that (if I remember correctly) it would fit best in the frame of a 135mm lens (which I don't have) and IMX571 camera, possibly also a Redcat51, but I'm not sure

if you guys, or anyone else wants to start a group project to image this nebula, plz count me in as a post-processor

It's almost certainly related to the hot luminous B-type star in the centre, Pi Aquarii. There are similar nebula around Spica, Delta Scorpii and Zeta Ophiuchi.

I need more info to locate this. I have a Rokinon 135mm and I need a first target for it

I have provided all the info there is in my post above, exact coordinates as well But you would need mono+Ha in order to get the most from it.

Dont underestimate the power of f/2 and a 5nm dualband filter

I've got both mono with 3nm filters and OSC as well as two F/2 setups. I don't underestimate, but I know the efficiency difference.

Yea fair, itll take longer but im sure itll be able to get the job done

Well, this is kind of a dead topic, but I think I found an image of this nebula - actually looks really interesting!
