While the price tag will give you pause, when it comes to astrophotography… you get what you pay for in many scenarios. The construction of the FF is of good quality, it is threaded on the end to accept 2†filters, and for DSLRs…the M48 Canon or Nikon adapter is required, which Skywatcher has available here (Amazon). The M48 adapter and FF combined achieve 55mm back focus needed for DSLR. I have uploaded a “first light†capture using the field flattener with the SW Quattro 200P Newtonian. The image is a single RAW, 60 second exposure, ISO 1600, shot with a Canon Rebel T4i modified, mounted on an Explore Scientific EXOS2-GT PMC-8.

If you have a Quattro. This is the coma corrector you want. Its not designed expressly for a range of focal ratios (though it will work), its designed for your f/4. Perfectly round stars all the way to edge of frame, though I did have to dial in the back focus first.
