hi poncho,
a non goto - not really no, a goto will let you get some of the brighter deep sky objects with exposures up to about 30 seconds max.
As Raymo says planets are fine because they are bright.
Saying all that I know people have tried on the brighter elements of the brighter ones. if you have a dslr you could try bright stars, bright binary stars, maybe a bright open cluster, other things to try would be the trapezium area in Orion nebula, the brighter smaller planetary nebulas like ngc 3242, ngc 6302, the homunculus nebula (example
http://www.iceinspace.com.au/forum/s...d.php?t=144669 very short exposures).
You would have to do a few trials to see how long you could geta away exposing for it might be 2 seconds or less. whatever you take though take a lot of data on it.
I'm not sure how long you can tweak webcam exposure setting for though a dslr would give you more of a chance. a webcam would be great for the planets and it is a good time to look at Mars, Jupiter and Saturn.
the skywatcher collapseable goto dobs do have upgrade kits to make them goto or it can be possible down the track to buy HEQ5 and use the dob tube on the equatorial mount to photograph.
