Every day I watch the drones come in to recharge.

Download their collected Intel, upload/install the daily firmware updates. Birds? What BIRDS man.....what birds. 1300mm focal length doublet 96mm aperture refracting telescope with a 2x barlow using a digital camera with a CCD crop factor of 1.6 making for an effective focal length of 4,160mm. I think the digital zoom is a factor of 10x.
