Initial Setup: Telescope with focul reducer

Initial Setup: Telescope with focul reducer was created by Mr Jacques Prince

Probably a dumb question:

When setting up your Scopes in the initial setup. If your scope is fitted with a focal reducer (x0.8) do you calculate the focal length of the scope accordingly? e.g. I am using an Altair Astro 102ED-R: Focal length = 714mm. With x0.8 reducer this = 571.2mm

Yes, put the focal length with the focal reducer included. I suppose maybe in a future version we can add an option for focal reducers as a separate component, but for now, FOV calculation depends on the final focal length after all changes.

Easier still: Just add that in the setup instructions. Not too difficult to calculate what adjusted focal length is. I just wasn't aware which one was required.

Btw... I assume there is a rational why this figure is asked for. Why is it?
