M20 Trifid Nebula by Gerry Aarts212 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 aarts

Wedge Base71 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 panels691 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.

M33 Spiral Galaxy by Gerry Aarts366 viewsPart of the Local Group of galaxies that includes Andromeda and the Milky Way. M33 is not an ideal Southern Hemisphere object to view or image. I captured this one at Mudgee NSW when the galaxy was around 20 degrees above the horizon. 10 x 4 minute subs for a total of 40 minutes exposure.
