If you have one of the "lower end" Canon's like the T2i that I have there is another option. For about $320 you can have the filter replaced with an astrodon filter. http://www.astrodon.com/products/filters/astrodon_inside_dslr/ Clear skies, Dale.

Chuck:
I have the plain old 60D and have been using it for over a year. It's battery life is very good, I've never been able to run it down below 60% in a long day's shoot. HOWEVER, it depends on how you use the camera. If you use the screen a lot, as in constantly, you will run the battery down much faster. There is no real difference between the 60D and 60Da other than the filter so I imagine the battery performance would be very similar if not identical. The 60D has the same battery as the more expensive 5D and 7D series which is rated at about twice the capacity of the Rebel series batteries, in my opinion that match's up to actual performance. If you are concerned there is an A/C adapter available so you can run the camera off A/C power. However I really doubt you'll need it. A spare battery will probably cover you.

What about the "bulb" setting? Is it a battery-eater for long exposures? On Apr 6, 2012 1:06 PM, "Thomas Sevcik" <sfv1ts@hotmail.com> wrote:
For those who haven't heard as yet, Canon has just announced the new EOS 60Da with a modified IR cut filter able to achieve a hydrogen-alpha (Ha) light transparency of 656nm that is nearly three times higher than the standard 60D. Check out the specs at the B&H
website.
