The Levenhuk Ra f/4 Newtonian coma corrector is compatible with Newtonian reflectors of any brand. On f/4 reflectors, it minimizes comatic aberration, which greatly narrows the view. The corrector will allow you to observe the entire field of view with the same clarity both in the center and at the edges.
