The Winter Albireo
Catalogued as 145 CMa, the Winter or Southern Albireo is a beautiful pair in Canis Mayor. It is well visible even with small telescopes. The primary is yellowish-orange and the companion is a pale bluish white. As increasing magnification the colours began to fade compare to the Albireo in Cygnus. This stars are not related and can be seen as a pair because the perspective towards the Earth.

Colour Saturated Crescent Moon
http://www.rolfolsenastrophotography.com
Copyright: Rolf Wahl Olsen Link to high resolution image
My QSI683wsg camera is way too sensitive to take unfiltered images of the Moon, but on 8th February I noticed a beautiful crescent Moon rising just as I was closing the observatory in the early morning. I decided to try imaging the Moon through a NIR filter since this would be the band of least sensitivity for the camera, and fortunately I was able to grab this image using an exposure time of 1/20th second.
Since the image would be oversaturated through RGB filters I didn't manage to get any colour for this image using the QSI683wsg, but I then combined the luminance data with my earlier saturated Moon image from 2010: A Lunar Mineral Map
The libration differences made this somewhat difficult, but I was able to fit the colour data to the crescent with reasonable accuracy.
I then rotated the image 90 degrees clockwise and was immediately taken by the resulting mysterious appearence of the scene. Although this is our good old Moon, it looks more like being on approach to an alien planet or one of the moons of the outer Solar System, reminiscent of some of the Cassini images of Saturn's moons.
Image details:
Luminance (NIR): 8th February 2013, 16 x 1/20s @ -27C
RGB: 30th March 2010, 500 x 1/1000s
Telescope: 10" Serrurier Truss Newtonian f/5
Cameras: QSI 683wsg (Luminance), ToUCam Pro SC1 (RGB)
Filters: Astrodon NIR E-Series Gen 2
Taken from my observatory in Auckland, New Zealand

M101 and Company
http://fth.bounceme.net/
The Pinwheel is one of the more difficult galaxies to image at 21 million light years distance. Like the Milky Way M101 has several bright red hydrogen alpha rich areas similar to our own Lagoon Nebula. These collections of dust and gases are typically areas of new star formation and glow due to the radiation of the young stars within them.
If you look closely you can also spot at least twenty other small galaxies in the image including the edge on galaxy NGC5422 at 87 million light years distance (lower right) and the spiral galaxy NGC5474 (upper left).

Globular Cluster Over a Hydrocarbon Sea

A hypothetical carbon planet orbits around a star which, itself, is located just beyond the outermost reaches of a globular cluster. This cluster rises over the horizon, like some kind of giant moon lighting the night sky, with its shine reflected on the surface of a ocean made of hydrocarbons and carbon derivatives.
