Stars & Star Clusters
LocationBarry's Bay, Ontario, Canada
DateMay 5, 2011 12:19 -->12:34 AM EDT
EquipmentCamera: Canon Digital Rebel 300D SLR set at ISO 800 & RAW mode. Lens: Tamron 300mm f/2.8 lens, set at f/3.5 Mount: Super Polaris EQ. Tracked but not guided. Exposures: 6 x 60 seconds each = 6 minutes total. Stacked using Deep Sky Stacker 3.2.1; post-processing (levels and curves) done using The Gimp 2.6.
DescriptionThese are the globular clusters M10 (left) and M12 (right) in Ophiuchus. NOTE: The trail at upper right, I suspect, is a geosynchronous satellite because the trail is approximately 15 arcminutes long in each of the individual minute-long exposures. Extrapolating to one hour, this would be 900 arcminutes = 15 degrees. Since the Earth rotates 15 degrees every hour, this would mean the satellite is stationary over the same spot on the Earth. North is at upper right, approximately perpendicular to the satellite track.

EquipmentCelestron 11" SCT w/Hex Mask and Diagonal at 200X. Digital Camera Afocal,ISO 400, 5", f/8 in Good Seeing. Processed in XnView and MS Paint.
DescriptionThis photo shows the companion to Sirius (Sirius B), aka 'The Pup', in 'positive' and 'negative forms'. The 10,000 times difference in brightness between the pair makes the fainter star difficult to see with smaller scopes unless it is well separated in angular distance from the primary and the seeing is good. A hex mask makes it easier to see and photograph the Pup, but even so, I had to take numerous exposures to collar this puppy! Ernie Evans

LocationRancho Hidalgo, NM and Eindhoven, Netherlands
EquipmentTelescope: TEC-140 (F7) for RGB Telescope: 300mm Newtonian (F3.9) for Luminance Camera: SBIG ST-8300M Mount: AP900 GTO for Tec-140 Luminance:5 x 12 minutes, 1x8 minutes, 18 x 5 minutes Red: 6x5 minutes (unbinned) Green: 6x5 minutes (unbinned) Blue: 6x5 minutes (unbinned)
DescriptionThis picture is a collaboration between Bernard Miller from Phoenix, AZ and Arie Nagel, Eindhoven, Netherlands. Arie took the luminance date on his 300mm Newtonian and combined it with the RGB from Bernard's TEC-140. Both used the SBIG ST8300M camera. The image processing was done by Arie and Bernard.

EquipmentMeade 10" F/4 Schmidt Newtonian on Losmandy G-11 Mount. Cooled Canon 400D. Processed in Nebulosity and Photobrush.
DescriptionNGC 2682 (M67) is one of the oldest open clusters in the Milky Way (abt. 4 billion years), and has many stars similar to the sun. It also has numerous red giants. It has a yellowish cast due to a lack of bright, young stars. A total of 1 hour, 20 minutes of 3 minute exposures were taken at -8 degrees Celsius, and at an elevation of 8300 ft. Dark and flat frames applied.

DescriptionThe double cluster in Perseus is one of the most popular open clusters in the night sky. The two clusters NGC 869 and 884 are about 6800 and 7600 light years from Earth, respectively.
