Toucam FOV calculation help.

[Astroman]

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

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
