Description

This is the wider field that my piggy backing Samyang 135 caught when I recently aimed my RASA rig on this object (see https://www.astrobin.com/1pw200/B/).

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 knows?
