here's a long exposure thread of a quite recently released DSLR
here's a long exposure thread of a quite recently released DSLR
Without talking abt image quality, I think the longest exposure will depend on what kind of power supply the DSLR is using 
Even phrasing as "Whats the longest exposure a DSLR can do with a acceptable image", its still pretty subjective...
Speaking from what I've done on the 10D, I've done 1 hr with a BP511 (and it can go longer) but the noise is pretty high...

Thats in Mongolia.
Erm, any specific things you're looking at? Its shot using a Canon 10D w/ 17-40 f4L, f4, 2900s. Cable release of course. Not sure what else you wanna know. You can pm me if you want...

yup to the first point.seeyf said:
probably not to the second point.... then again, i've not tried, but i don't think stars move much in 10mins. also, your 8800 probably can't set as small an apperture as a dslr, which may result in overexposure unless you're very careful to ensure no bright light source is present....
ah, i stand corrected.
however, as nuts demonstrated, it has to be really dark.
not many places in singapore dark enough though..

not only that....near equatorial region, the star will not move in circle
they will move in straight line (almost), so u wont get the curve effect even after hours of exposure
reason is that the stars will move around north star but in singapore, we can never see the north star
actually star trail is rather easy to shoot if u stay near north pole, just find a dark, cloudless night with no moon, no aeroplane/car, no lightning, no house nearby. Even better if there are some structures that dun give out light, like tower, trees, hill....
