Humason 2-1 (2014)
One of the three planetary nebulas discovered by M. L. Humason during his time at the Mount Wilson Observatory. Any aspiring astronomer should read that short Wiki article at the link.
Here, the swirling, vaguely symmetrical nebula is seen in detail with two narrowband filters (F658N & F656N). The broad, blueish dots arranged in the X shape are simply diffuse diffraction spikes and are not part of the nebula itself. The central star is just discernible.
The image has been enlarged 200% from its original size.
These data were collected for Proposal 6347, A Search for Jets in Planetary Nebulae
North is up.
Hubble data is public domain. I do, however, request that you credit me for the processing of the image if you use it.
