Field of view FOV

[Conrad Cardano]

Hi

Quick question.

What is the field of view for the scope-in-a-box?

Thank you for reading this.

It's kind of an odd shape, but if you model it as a 1m dish, it's about 21deg.

 With an Optical Telescope,

the "Field of View" is all you can see.

 With a Radio Telescope,

the "Field of View" defines the angular field in which the intensity decreases from a max at center to 1/2 that power level at the FOV angle.

Beyond that, the sensitivity continues to decrease, but its effective 'Field of View" extends beyond that number 

        ( you may pick up Sun noise  / Ground Spillover noise much further than the calculated  FOV angle , etc )
