New owner of k-x

Well after researching for months and hanging around the forums I finally decided on the K-x. Should be here within a week.

Have a couple questions:
i have 2 k-mount lenses was wondering about the quality of them. Both are from sears. one is a 135mm 1:2.8 and the other is a 50mm 1:1.7.

I also have a vivitar auto 30d and was wondering if that would work on it also?

was looking around the picture gallary has anyone ever tried to take and pics of planets or deep space with it?

The lenses should work just fine, in manual focus and manual exposure modes. See here for a review of the 135: Third-Party Lens Review Database - Sears 135mm f2.8 Auto Multicoated Lens Reviews

The flash should work, but don't quote me on that, and make sure you check the voltage first!

Sears 50mm 1.7 should be good--never had one, but I heard they were good. Sears 135mm 2.8 is very decent, except that it gives some visible purple fringing.

If they are from Sears, they're actually likely good quality-lenses, but watch out for the dreaded Ricoh pin which may be present: these have an unfortunate tendency to get stuck in autofocus cameras' AF screw sockets when mounted, thus basically sticking that lens on there. Some Sears lenses will have that, (If I'm recalling correctly) so you'll want to check. If they don't have an 'a' setting on the aperture ring, you should be safe, though.

I don't see an 'a' but how can i know for sure. I tried the 2 lens on a body at Fry's electronics and both worked.
