Title: Arcseconds Per Pixel
Post by: Daniel on Aug 02, 2009, 15:12:43

Hi All, I was trying to find out trying to find out the FWHM in my hyperstar images for calibration purposes and need to find out how many arcseconds per pixel my images are coming out at, can anyone tell me how I would go about this?

Thanks

Daniel

Also you can take an image of something & then compare it with for example star charts on SkyMap Pro to get width/ height & then divide by number of pixels on sensor...

John,

What a brilliantly simple solution!
