Canon Rebel T3 (EOS 1100D) Wide Field Gallery
                                                             
 

Piggyback Astrophotography

All of the images in this gallery were taken with an unmodified Canon Rebel T3 (EOS 1100D) using an EF75-300mm f/4-5.6 zoom lens. I mounted the Rebel T3 piggyback on top of my C8, as shown below. All images were acquired unguided at f/5.6 with only a rough polar alignment.
