Hi, Calebk,
You are right, I forgot to include that.
So rightfully, it should be 200 x 1.6 crop factor = 320mm x 1.4 converter = 450mm.
Is the calculation correct?

Yup I should think so. 448mm to be exact.

Hmmm......even with that, it's considered a very good lens. How much did the lens cost you?

Hi
Tonight is full moon (15th of lunar month). The moon is quite round. Took some shots to test out. True enough, full moon does not give much shadow and hence craters are not very well defined.

Here is one of them.
