Detailed Information:
M057 represents a collaboration of mine to process data acquired by Frank Colosimo. I will quote Frank on the details,
"This is one of the first images from my new roll off observatory in New Ringgold, PA. Thanks to Chris for his expert processing, which brought out the faint halo around this planetary nebula that we noticed when we started working with the images." I would add that this level of visibility around the Ring nebula is usually only seen with H-alpha exposures being combined.

M057 was observed on 31 January 1779. It is described in the NGC: "A magnificent object. Annular nebula, bright, pretty large, considerably extended, in Lyra." That pretty well sums it up. This object is located between Gamma and Beta Lyrae. Visually it appears like a grey smoke ring. On a video astronomical image my daughter described it as the "Cheerio nebula." Kids watch too many commercials these days! This is a planetary nebula in the form of a torus (doughnut shape) for which we are looking down the end or through the hole. This nebula was formed by central star which collapsed to form a White Dwarf star seen centrally in the image.

The small spiral galaxy located to the right and below M057 is IC 1296. It would normally not be so apparent, but I processed it to make it more evident because Frank had captured so much detail and it looked quite interesting. IC 1296
