New nebula "Roig1 Prades Sky" in the outer regions of M 33

[Uwe Glahn]

In December 2023, Spanish Amateur Astronomer AleixRoig discovered a new [OIII] emission nebula in the outer regions of Messier 33 [DOI 10.3847/2515-5172/ad12d1 (https://iopscience.iop.org/article/10.3847/2515-5172/ad12d1)]. He named is "Roig1 Prades Sky".

Last new moon I gave it a try with my 27-inch and the nebula was clearly visible as a longish smudge with [OIII] filter. So, this new nebula is also accessible for us visuals and I think it also could be a target for the 20-inch class.

Hi Uwe,

Wow, congratulations! And thank you for suggesting this as a target for the 20" class. I'll give it a try.

By the way, have you also tried Maasewerd 2 Nebula, which can easily be seen on Aleix Roig's image?
In fact, Roig 1 Prades Sky Nebula can be seen on Peter Maasewerd's image:

Thanks for your feedback and input, Robin.

And, no, I did not try the new PN Maa 2, but the object is on my list now. Thanks.
