Some bird in the Olympic Forest Park (Beijing). Apparently, winter is colder than I thought.

I put a cheap 10x42 monocular telescope in front of my phone's lens to get those pictures. You may notice the dispersion cause by the telescope.

I'm planning to buy a new telescope with ED lens which claims to fix or reduce the dispersion, but it's pretty expensive after I renewed my domain, dns and other stuff.

One more reason to get a job.
