Canon EF 200 mm f/2.8 L II USM
This is the only astrophoto using a DSLR from our recent vacation to Costa Rica. I was prepared with a tripod and SkyGuider Pro in case of a clear night but all I got was a quick shot of the moon with me lying on my back. It clouded up shortly after. It was a very good trip though and the weather was fair during the day so we were able to enjoy it.
