Hi all, well I am interested in doing some astrophotography (as well as normal photography), but I don''t have a large budget. I have seen that cannon cameras seem to be the preferred camera, but i have noticed Sony a100's selling online relatively cheap (around $300). Just wondering what your opinions are on this camera

. It would be used for a variety of uses, including normal photography, macro and astro.
Thank you
P.s the specs are in the following link
