Hi all,

This is my first attempt on shooting the moon, using prime focus with AstroMaster 130EQ.
But i'm using a bit different approach, by using a reversed lens to reach higher magnification, instead of directly attach the camera body to the focuser via an adapter (which i believe won't work since the focus point is far inside the focuser)

Here's the configuration:
Telescope's focuser -- 10cm extension tube -- reversed lens 28mm f/2.8 -- body.

I think it's around 32x-40x magnification (i'm not sure). Can anobody explain how to calculate the magnification using this kind of method?

need your comment/critics/suggestions...

thanks!
