Best webcam for astrophotography 2018

Astrophotography requires a specific equipement : a telescope, a mount and of course an astrophotography camera. But this device can cost hundreds of dollars and that’s expensive for people who have a small and limited budget.

Fortunately there’s a solution : Use a good Webcam astrophotography. This solution costs only few dollars (for example the excellent Logitech C270 is under 25$ ! ) and you can obtain very good results when you connect it to your telescope using a Barlow lens. I used for 2 years a webcam for telescope and i was able to image almost all the planetary system : The moon and its craters, Venus, Mars, Jupiter, Saturn, Uranus and Neptune! (check my gallery of planetary images with a webcam).

This is certainly the best astrophotography webcam. I used it and i can recommend it to any astrophotographer because it’s simple to modify (by removing the lens and attaching a webcam adapter for telescope), high resolution, high sensibility and high quality image, and the most important is that this webcam is compatible with astrophotography softwares like Sharpcap.

Also thanks to its USB 2 interface, you can obtain up 30 images per second ! That’s excellent to freeze the atmospheric turbulence.
