Looking at an add for a schmidt newtonian,I assume that every thing else is like a regular newtonian other then the corrective lens. The primary mirror is the same, though I assume the secondary mirror is attached to the corrective. But, does the corrective lens in any way add or double the focal length of the scope? Thank you for the information. Really appreciate it.
