Lyra 13/10/06
Taken on 13th October 2006 from SIGMA's observing site, using a guided EOS 300D camera with 150mm telephoto lens. Alan found that the constellation of Lyra fitted just nicely in the field of view of the lens!
The sharp-eyed amongst you may spot the tiny blue-green disc of the Ring Nebula, M57, between the two bottom stars of the constellation, Gamma and Beta Lyr.

Barnard's E 22/08/07
The above image of B142/B143 (Barnard's E) in Aquila, which was taken on 22nd August 2007, is actually a stack of 3 x 150 Second exposures. Although the sky transparency was good, the seeing wasn't particularly brilliant and so a lot of processing had to be done on the individual images as well as on the final stacked image.
Equipment used: Canon EOS 300D, Sigma EX 150 mm APO lens, 1.4 x APO teleconverter, Vixen GP photo guider. Exposure details: 3 x 150 Seconds @ F/5, ISO-800.

Lunar Eclipse 21/02/08
After 2 weeks of high pressure, the barometer suddenly dropped on Wednesday 20th February and the forecast for the eclipse on the 21st was not good. By some minor miracle the clouds cleared and the wind dropped for the start of the event. I saw about 10 minutes of totality before the sky completely clouded over. This image was taken at 3:04 a.m.
Equipment used: Sky-Watcher ED80, HEQ5 mount, Canon EOS 300D at prime focus. Exposure details: 5 Seconds @ f/7.5, ISO-400.

NGC 2023, 2024, IC 434 et al 28 thru 31/12/08 - Alan Tough
Alan took advantage of the clear, frosty nights at the end of December to image the Alnitak region of Orion. The final image reveals a smorgasbord of nebulae: Barnard 33, the Horshead Nebula, is silhouetted against the bright emission nebula IC 434; Next to 2nd-magnitude Alnitak is the emission-type Flame Nebula, NGC 2024, with its dark dust lanes; Close to the Horsehead is NGC 2023, an emission and reflection nebula. The multiple star Sigma Orionis is at the top-right corner of the image.
Imaging and guiding equipment: Sky-Watcher Evostar-Pro 80ED (f/7.5), Sky-Watcher Evostar-Pro 100ED (f/9), HEQ5 mount, Canon EOS 300D at prime focus, Astronomik CLS filter, StarShoot Autoguider, PHD guiding software.
Exposure details: The sub-frames were taken between 28 and 31 December 2008, giving a total exposure time of 2.5 hours. The average temperature during these sessions was -8 degrees Celsius. Processing time was in excess of 12 hours. Photoshop (with Noel Carboni's Astronomy Actions) and Neat Image were used to process the subs.

M45: The Pleiades 09/01/10
This image of The Pleiades was taken from Elgin on January 9. Thin high level cloud caused me some processing difficulties though.
The 50 minutes worth of data were processed using Photoshop 7 (including Noel Carboni's astronomy actions and StarSpike Pro plug-in) and Neat Image.
Equipment used: Sky-Watcher ED80, HEQ5 mount, Canon EOS 40D at prime focus, Astronomik CLS filter. Exposure details: 5 x 10 minutes @ f/7.5, ISO-800. Guiding equipment: Sky-Watcher ED100, StarShoot Autoguider.

Jupiter 26-27/09/10
This is my second go at imaging Jupiter with a DFK astronomical video camera and 9.25" SCT. The seeing was good enough to let me use a 2.5x Powermate, but I'm still hoping for more stable skies before the winter sets in.
With the 'loss' of the South Equatorial Belt, the Great Red Spot certainly stands out. However, the 'shadow' of the SEB can still be seen. I was also pleased to pick up the North Temperate Belt as well as some dark streaks in the South Polar Region.

Comet 103p Hartley 07-08/10/10
Comet 103P Hartley and the Double Cluster in Perseus. 10 sub-frames were taken between 23:46 and 00:10 UT on 2010 October 07-08. The data were processed using Photoshop 7, Noel Carboni's astronomy actions and Neat Image.
Equipment used: Sky-Watcher ED80, HEQ5 mount, Canon EOS 40D at prime focus, 0.85x Reducer-Corrector. Exposure details: 10 x 90 Seconds @ f/7.5, ISO-800. Guiding equipment: Sky-Watcher ED100, StarShoot Autoguider.
