Lightweight Apochromatic Refractor

[the_blacke]

Hi all,

I'm thinking about getting a lightweight APO refractor for piggyback widefield astrophotography on top of my main scope. So if you've got something sitting in the cupboard not being used that you might want to get rid of, let me know. I'm thinking something in the vicinity of 400mm so something like a ZenithStar 61 or possibly a 73 if it isn't too heavy.

Thanks,
Ross

Edit: I'm in Melbourne's north-east, but if you can pack it shipping could be done.
