We have several Coelogyne cristata but this is the first plant to begin blooming. The flowers are not entirely open yet so I'll probably update next week with a new picture. They require high light levels but not direct sun. We have then in a room with ferns and block summer sun with a thin fabric tarp which we remove in the fall/winter (there is another coating on the glass).
It typically flowers in January/February so I'm not sure why it decided to flower now. They need cooler temperatures than most orchids as well as a rest period with reduced watering. One of the more distinct features is the warping at the edge of the petals. It's generally very obvious but less pronounced in the photo below.
