I finally got this image to look like something. It was a tough one:
From Wikipedia:
The Tulip Nebula, or Sharpless 101 (Sh2-101) or the Cygnus Star Cloud is an emission nebula located in the constellation Cygnus. It is so named because it appears to resemble the outline of a tulip when imaged photographically. It was catalogued by astronomer Stewart Sharpless in his 1959 catalog of nebulae. It lies at a distance of about 6,000 light-years (5.7×1016 km; 3.5×1016 mi) from Earth.
***************************
Other prominent characteristics of the region seen in this image are the dark lanes of dust with scattered ionized gas in a massive cloud of stars that are a part of the Cygnus arm of the galaxy.
The Tulip nebula is in close proximity to microquasar Cygnus X-1, site of one of the first suspected black holes. Cygnus X-1 is the brighter of the two stars (the right star) near and parallel to the top center of the edge of the image. It is the brightest object in this region of the galaxy in x-ray images, though it isn't the brightest object in this optical image.

Panstarr is probably too low on the horizon for you by now, but I suspect you can still see Comet Lemmon. You live down under, right? It should be viewable from where you live. It will be in or near constellation Phoenix on Saturday evening. It looks like it is about magnitude 4-5 right now, so you will likely need binoculars and dark skies to see it. But if you can get to a dark site with binoculars and can find it, it should look very good.

"In short, Meyer has shown that his first disastrous book was not a fluke: he is capable of going into any field in which he has no training or research experience and botching it just as badly as he did molecular biology. As I've written before, if you are a complete amateur and don't understand a subject, don't demonstrate the Dunning-Kruger effect by writing a book about it and proving your ignorance to everyone else!
