As a side note to the question about the 300mm lens this is what I just got although it's probably a touch out of focus it shows AR 11476 easy enough so it should show Venus.
This was stopped down as far as I could go f/40 and used my fastest exp 1/40000. Even though the ND400 says it's good for use on the Sun I would not recommend it unless you had it connected to a laptop or at all.
Grab some solar film instead.
