How to use fisheye lens?
« on: August 23, 2016, 03:35:31 PM »
I'm trying to build an allsky imager with the minicam5s, but I'm having trouble with the optics. I know that I need a fisheye lens to widen the camera's view, but what lenses would work well with this camera? How do I figure out if I need intermediate lens?

      For miniCAM5S , you need the C/adapter lens. CS lens can not work due to the back focal.  I recommand you using the QHY5L-II to build the all sky camera since QHY5L-II support the CS lens. You can use the 1.25mm eyefish(CS lens with QHY5L-II)
