Our Observatory is CLOSED tonight
The Milky Way shot by Graham Caller on a very clear night in Sept.
Albireo is the bright star by the red arrow. The Dumbbell Nebula is to the left of the yellow arrow.
This is a combination of 90 x 10 secs exposures, 30 lights and a variety of darks, flat, and bias frames, stacked and processed using Deep Sky Stacker software.
On Monday (5th November – with fireworks exploding nearby) we captured some images of Jupiter with the Alan Young telescope.
We used raw format on the Canon dSLR (.CR2), for the images.

Here is an image of Jupiter:
And below, a composite image of Jupiter (1/200 second exposure) and its four “Galilean” moons – Io, Europa, Ganymede and Callisto (1/4 second exposure).
Image captured by Graham Caller of the area in Cygnus, showing the North American nebula (NGC7000).
The nebula is between the brightest star in the shot (Deneb) and the brightest ‘orange’ star at the 7 o’clock position from Deneb. It looks like a reddish fuzzy blur shaped like North America.
Composed from:
26 x 10 sec subs on an f1.8 50mm lens. ISO1600
Raw format, stacked in DSS
This image of the constellation of Cygnus (the swan) was captured by Cadsas member Ivan Walton.
From 24 stacked 10 sec frames taken at 800 ASA
One of our members, Graham Caller, captured this image showing m31 and M110 in Andromeda.
He describes it.. “Andromeda stacked shot taken last Friday. I’ve had to really eek out the detail but you can see the disk of Andromeda and M110 faintly.
Details were:
25 x 10s exposure
f1.8
ISO 1600
50mm focal length
RAW format stacked in Deep Sky Stacker and post processed in Photoshop
M109 26 March 2012 Processed & desaturated
M51 Whirlpool Galaxy 26 March 2012 Processed
M109 and M51 taken with the Alan Young telescope.
Images of the Moon, Venus and Jupiter taken on 25th February 2012.

Quite a number of people (including several students) braved the freezing temperatures (-5C) to benefit from clear skies!
In the observatory, under the ever present risk of a thick layer of frozen snow perched periliously on the edge of the roof, the AY scope secured some fine images to add to the growing collection of Messier objects (principally open clusters).
M103 (NGC 581) an open cluster in Cassiopeia
M41 (NGC 2287) an open cluster in Canis Major
NGC 2264 The Christmas Tree Cluster & the star 15 Monoceros
M34 (NGC 1039) another open cluster in Perseus
M67 OpenCluster - 27 Jan12 (click for larger)
Continuing our quest to capture images of the Messier objects, we secured another one at last night’s observing session
This image was captured using the Alan Young 22.5″ reflector telescope.
M67 (NGC 2682) in Cancer. An open cluster known to be one of the oldest in excess of 10 billion years old!!
