Hi All,

I have added my 400D to Stellarium but need some help on how to add my Lenses to it. The main one I want to add is the 18-55mm Lens.

I assume I need to add it as a Telescope. But I am not sure what the Diametere Parameter is. And for the FL it does not seem to accept a Range so I assume have to fix it to somwhere between 18 and 55.


Regards
Fahim

Invert the formula for F ratio:

F ratio = focal length / aperture

so:

aperture = focal length / F ratio

You could put multiple entries for various zoomed lengths.
