Deep Sagittarius

Keith,
I'm always amazed at how sharp you get the focus,
At this rate you could give up the day job.

:shock:

Thanks guys, I'm glad you think it's a good shot

I don't know too much about lenses; any chance you could explain about the Canon ef 85mm f1.8 lens at f2.8 you're using? What/how do you operate an f1.8 lens at f2.8?

Michael, easy, the lens operates at a maximum aperture of f1.8, it's widest setting to leave in the max ampunt of light, but many photograhpers 'stop' the lens down a notch or 2, the result being that stars will appear a little sharper, operating at f1.8 is extremely 'fast' meaning too much light will be gathered, and the shot will not be as sharp to step down, there's a dial on the camera to allow you to easily control the aperture of the lens, but if you stop down too far, too little light will be gathered, and the shot will appear dim, so you'd have to increase your exposure time.

Anyone know what the various deep sky objects are that you can see in this image?

Bart, I can eaily count 11, but i'm sure there's a lot more, I'll label this one and put it in the all - ireland sky project.

At this rate you could give up the day job. Smile

I WISH!!!
