Number of objects available for imaging aside (thanks for recommending them), For those like myself who don't have actively cooled cameras like CCD's we suffer from high amounts of noise due to warmer sensor temperatures.
Taking photos with a Canon EoS Ra in North Queensland during the summer may not be very practical unless you can keep the camera cool
I remember trying to image the Aurora Australis along the Great Ocean Road a while ago on a classic Canon EoS 5D and after 2-3 images of 30+ seconds, I was seeing a magenta/purple haze to the right of my images.
Edit: I guess I'm not really answering your question on object availability, but just something I noticed during summer which may limit what I do compared to winter.
