MWP 1 (aka Methuselah Nebula) and ALV 1

[gorann]

MWP1 (PK080-10.1) has been called the Methuselah Nebula (as it is very old, about 150 000 years). It was discovered in 1993 by C. Motch, K. Werner and M. Pakull. This bipolar planetary nebula struck me as relatively bright for being so old, and indeed this has puzzled astronomers. Because it is old it is also very large (about 15 light years long).  The distance from Earth is about 4 500 ly. More info about it here: http://annesastronomynews.com/photo-gallery-ii/nebulae-clouds/mwp1-by-don-goldman/

ALV1 (Alves 1) is that smaller spherical PN below MWP1. It was discovered by Portuguese amateur astronomer Filipe Alves in 2009 (https://arxiv.org/pdf/1206.2477.pdf) while he was imaging MWP1.

I am not sure if the faint Oiii clouds seen in the image are associated with the PNs. Maybe someone here knows?

Nice image goran.

I wonder what those other two objects are; south-east of MWP1 (looks like a very faint oval object) and also north-east appears to be a hazy green object.

Thanks, and yes I also wonder. I also see them in other images of these objects on Astrobin. They seem to be embedded in the Oiii clouds. By the way I made a revision with a bit more blue signal, so more Oiii clouds:

Thats a great image of something i dont think i've seen before.

Thank a lot! Yes it seems to be rather rarely imaged
