Piggyback photography is one of the most popular and easiest ways to get started in astrophotography.
Simply by attaching your camera, with its own lens, atop the telescope tube wide-field photos of the Milky Way of remarkable detail and clarity can be taken - even with short exposures.
When the telescope is mounted equatorially, the camera can use the telescope's tracking coupled with guiding through the main telescope for long exposure Wide-field Astrophotography.
Suits 7" Maksutov and all 8" SCT's.
