Eclipse Megamovie Camera Spec Calculator

To produce a 200px diameter Moon on a 1920x1080 frame (Full HD) without upscaling would requite a minimum plate scale of 9"/px. Based on that we can calculate minimum camera resolution from Camera Sensor Size and Focal Length of Lens. Alternately we can also do a reverse calculation and figure out what range of focal lengths will produce the necessary image based on the sensor size and resolution of camera.

Calculate range of suitable lenses based on the camera type and resolution:

Select resolution of your camera:
Select Sensor Size of your camera: Camera sensor sizes vary slightly from the standard full frame and APS-C by manufacturer and model
Maximum vertical Field of View:
Minimum vertical Field of View:
Focal length of your lens should be between and
This is only an approximation. Camera sensor sizes and resolutions vary slightly by manufacturer and model, so this range might be somewhat different for your camera

Calculate Minimum Camera Resolution based on focal length of lens and camera type:

Select Focal Length of your lens:
Select Sensor Size of your camera: Camera sensor sizes vary slightly from the standard full frame and APS-C by manufacturer and model
Vertical Field of View: Your focal length is too high!
Minimum Camera resolution: More than 2Mpx is needed to produce a frame with at least Full HD resolution
