Image of the Ring Nebula, aka M57, taken with my 10" RC telescope and a diffraction grating. The diffracted stars are all streaks but the diffracted nebula is just two blobs--the blue blob is O-III wavelength and the red blob is H-alpha.

I took this picture of Comet 103p/Hartley on the morning of October 8th as it passed almost in front of the Double Cluster.

In Thailand, customers are greeted by Ronald McDonald with a wai instead of a wave.
