That is because a Newtonian is not as sharp as an RC (my opinion and certainly many others) and a fast Newtonian is not always the answer Mark. Tools for the job.
Lever action alone makes it impractical for imaging. Not to mention flexure of the tube.
A Newtonian is not always going to be useful in all situations.
