A great alternative for more expensive cameras with the same chip. I used it once so far for guiding and it worked well. I wish it had a driver to work on ARM processors like the ones used in Raspberry Pi. One thing that I not happy about was that my camera came with a smudge on the lens and sensor and I had to clean it myself. The seller was extremely prompt in replying to my message which was much appreciated. Oh, and the shipment was pretty fast considering it came from China.
