Orion Nebula with the Tair 3
Feb 24, 2012

I just constructed a barn door tracking mount so I can start making long exposure astrophotos. It isn't quite finished yet, but I couldn't help jerry rigging it to use it for a little while tonight.

I attached my Tair 3 300mm lens and camera to the barn door tracker and here is what I got with my first photo.

It is Orion Nebula taken at F4.5 and a 10 second exposure at 1600 ISO. You can see that it isn't perfect yet. I don't have the tracker fully finished, so it wasn't aligned quite right to Polaris, so the stars are a little oval.

Once everything is working and adjusted right, I should be able to get up to around 5 minute exposures with the tracker. When I can do that, I can stack multiple images to get a hubble-like photo. It will definitely take some experimenting and learning though since this is my first step into astrophotography.

Here is the 10 second exposure. A longer exposure would show much more of the nebula and many colors, this is just my first test image.
