Tarantula Nebula by Gerry Aarts157 viewsThe Tarantula Nebula is locted in the large Magellanic Cloud approximately 160,000 light years away. There are thousands of massive stars blowing off their material to create this huge gas cloud that has been heated to millions of degrees by these stellar winds and also by supernova explosions. Imaged at my Mudgee Observatory, this is a a composition of 2 x 10 minute exposures. Equipment: Celestron HD Edge11 scope, f.5 reducer. CGEM Mount for tracking only. SBIG ST4000 camera & AO8. Guiding was with the AO8 unit only. gerry aartsDec 28, 2012

Omega Centauri by Gerry Aarts42 viewsEasily the lost spectacular globular cluster visible, you can see this beauty with a decent pair of binoculars or modest telescope. Estimated to contain 10 million or more stars and floating in space outside of our own Milky Way galaxy. This image is a combination of 10xc30 seconds exposures.gerry aartsMar 29, 2012

Supernova 2012aw by Gerry Aarts98 viewsSupernova 2012aw was discovered 16/03/2012. This image was captured at Bundaleer observatory on 23/03/2012. M95 is a norhtern hemisphere galaxy discovered by Charles Messier in March 1781, rather fitting this Supernova was also discovered in March 231 years on. I got clouded out again during the image capture process so this is only 15x2 minutes exposures with my Celestron HD Edge 11.gerry aartsMar 29, 2012

NGC1365 Galaxy by Gerry Aarts83 viewsOne of the best examples of a barred spiral galaxy located in the southern hemisphere. Imaged at Bundaleer observatroy near Mudgee NSW. 56 million light years distant. Celestron HD Edge 11 telescope. CGEM mount, Meade DSI III camera. Guided with Orion autoguider. Only 3x4 minute exposures then I got clouded out. The deatail is however good due to excellent seeing that night.gerry aartsMar 29, 2012

Trapezium: Centre 0f the Orion Nebula by Gerry Aarts244 viewsThe Trapezium is the central portion of the Orion Nebula (M42). This is a 30x 20 seconds stack of images (total 10 mimutes of exposure. Imaging this bright region of M42 and managing to keep the central 4, bright stars seperated is qiute complex. Imaged at my Mudgee property "Bundaleer" on 30/12/2010. One of only 2 images for the whole of 2010.

M20 Trifid Nebula by Gerry Aarts360 viewsOne of my better nebulae images from Linden Observatory 04/05/2008. Distance estimated at 5200 lightyears. Red emmission nebula and blue reflection nebula shows a wonderful contrast. The star colours are also amazing, a myriad beautiful yellow and blue stars reveal themselves in this image. 9x30 seconds combined images. Celestron GPS11 with f1.8 Hyperstar lens, Meade DSI III camera.gerry aartsNov 28, 2009

Wedge Base89 viewsIn order to ensure a rock solid mount, I decided to use a double layer of ply for the wedge base. 2 pieced of ply were glued together with 2 part epoxy.
If you look carefully at the image above, you can see the circle marked on the surface of the wood with cross lines drawn with a protractor to indicate where to drill the Azimuth / RA adjustment holes. A drill press makes this job MUCH easier as you don't need to worry about the holes being perfectly vertical.

Side panels897 viewsThe above shot shows the wedge sides under construction. To ensure that the side panels were identical during the shaping phase, the 2 pieces of plywood were first screwed together.
I then added the altitude / declination adjustment slot. My main observing location (home in Sydney) is at Latitude 33 Degrees, 45 Minutes South, so to allow for my "infrequent" local travels to dark sky locations outside of the Sydney basin I cut enough play in the slots for 29 - 37 Degrees Latitude.
