Hi again Nige. On reflection[pun intended], I think there is something
going on here that Mental and I are missing.
Firstly, I don't think that a mirror that was so bad that Venus looked
like a bloated star would ever leave the factory; or If it somehow did,
the buyer would have returned it as unuseable.
I truly don't wish to be patronising, but are you absolutely sure that
you were looking at Venus and Jupiter? You state that Jupiter is very
small through your 6.5mm EP. about a mm. That is impossible at the
approx. 120x that a 6.5mm gives. Even at that modest mag it would be
quite large, and even with a poor mirror it's 4 brightest moons would
be readily visible.Pulling EPs apart is usually a no no, and if you separated
the lenses, you possibly stuffed the EP, as each lens has a proper
rotational position relative to its neighbour, in quality EPs at least. Firstly, I suggest you borrow
a known good EP of any focal length, in order to narrow down the
problem to either the scope or the EPs.
