Toucam FOV calculation help.

[Astroman (Andrew Wall)]

Does anyone know the FOV of the Toucam in Degree, minute, seconds for height and width of the frame... I am trying to work it out for my Skywatcher 8" f6 Newt. Trying to do a CCD frame in Skymap Pro.

thanks..

Hi Andrew

I usually use elements from the following data to input into my planetarium programs, which then calculates the FOV based on telescope details.

ICX098BQ chip
Number of pixels: 659 (H) × 494 (V) approx. 330K pixels
Number of pixels in image: 640 (H) × 480 (V)
Chip size: 4.60mm (H) × 3.97mm (V)
Unit cell size: 5.6μm (H) × 5.6μm (V)

Cheers

Dennis

Field of view = 57.3X(chip dimension/focal length) degrees

so for 4.6x3.97mm and FL 1218mm, FOV is 14.1x11.3 minutes of arc

Hah, who needs computers and planetarium programs when we've got Bert.

Our good mate Bert posted this once. A FOV Calculator

Thanks for that FOV calculator link Andrew, Bert and 1ponders, very good
