Hi Mark,
Thanks for your reply, that was the lens I ment, edited my last thread to be correct.

But the question, how does it perform today relative others, Sigma, Tokina etc does the other perform better today relative the Canon lens hen using them as an astrograph?

And if looking for a smaller telescope/astrograph like these:,57322,53101,55190

I have no experience of that kind of telescopes, anyone who have experience from them?

How does it perform realtive a Canon 300 mm f/4L lens?

It still a bit too big for me, but curious to know.
