I've got a Canon DSLR shell which takes EFS lenses here that was bought in a charity shop a few months back. A ten year old unit, the 350D Rebel.
Canon EOS Rebel XT / 350D Review
Whilst it's classed as an entry level camera, it has more bells and whistles than I wish, and am still working my way round the 'manual' functions, so currently all pictures are taken with the iPod 6.
Additionally the iPod is usually in the pocket and can be used in seconds, the DSLR is a purposeful still camera, needs to be lumped around in a bag, then fit the lens as it doesn't quite fit in there with the Tamiron item (also a charity item), the original Canon lens is rather cheap.
But I have taken some images with it in the past month and the Tamiron is rather good with low light level stuff so I'll have a go with the telescope at some point.
