Hi all,

I got the OAG tracking on a star last night after a few hours. I found the best way to find a guide star was to replace the Orion Starshoot auto guider with a eyepiece to scan the perimeter of the FOV around the target.

This image is made up of 30,60 and 240 second exposures, with over 60 images stacked. Astro 40D at iso 800 and 14" SCT at f6.3

I used star reduction in photoshop to reduce the size of the central star. It's the first time I have used actions in photoshop. It reduced the star size, but I am not too sure about the colour on its fringe.

Thanks Ric.

Here is another processed image this time without the 240 second exposures, as they seem to just burn out the centre.
