Capturing the Milky Way

[Jon Ruyle]

Here is one I took last month from my front yard of the saggitarius/ scorpio area.


It was only a 30 second exposure, taken at 16mm but cropped. Longer than 30 seconds would have caused the stars to blur (even more than they already are)


I keep planning to try a longer exposure with a tracking mount, but I've had clouds at the other new moons this summer

What ISO are you guys using? I can

What ISO are you guys using? I can't see myself going above 1600.

Under dark skies, almost always 1600.


ETTR then ITTR. Increase your exposure as much as possible without causing other problems (e.g. too much motion blur), then, if you still have room on the right of your histogram, use "ISO To The Right" -- increase your ISO as much as possible without clipping any desired highlights *or* going over the maximum useful ISO setting. For a given (fixed) exposure, high ISO has *less* noise than low ISO. That may seem counter-intuitive, but it's true. The maximum useful ISO on any Canon camera is never more than 3200, and usually no more than 1600. (That's because 6400 and above is a braindamaged digital operation in the camera.)

Thinking I'll try 17mm, 1/30 sec @ 1600 ISO and see how that fares. WB a concern at all? I suppose I can just adjust that later in LR.

I usually go with daylight, then play with it in post to see what looks best.

1/30 sec is not going to be long enough.


My typical settings are ISO 3200, 10-30sec exposure, f/4.0 -f/5.6 depending on the level of exposure I want to achieve.
