This is my first attempt at attaching my Canon 60Da DSLR to a telescope for deep sky imaging.
I was pleased with the sharp focusing centrally but there was quite a lot of coma artefact at the edges which I was able to mostly correct with Photoshop. I was a bit surprised to see so much coma as I have a Planostar field flattener attached to the scope – perhaps I need to put a spacer between the field flattener and the camera.
The dark channels (Bok globules) show up quite clearly around the central open cluster.
This is an integration of 9 x 60 second and 2 x 120 second exposures with an Altair Astro 480mm f6 refractor and Canon 60Da at ISO 800.
