Description
The AT60EDP was built for imagers who wanted a grab-and-go widefield astrograph without the fuss of spacing a separate flattener or reducer. It delivered on that promise 17 five-star reviews, round stars to the corners, and owners who stopped shopping for alternatives after using it. It’s discontinued now, and the closeout price makes it an even better value than it was at full retail. If you image wide fields and want a scope that’s ready to shoot the moment you attach a camera, this is one of the most straightforward imaging setups we’ve ever carried.
