The Mak-Newts are more comparable to apo's - there is a contigency here that swears by this. Mak-Cass (the Meade 7" is a Max-Cass) has larger central obstruction but is small and is designed in a way that is hard to screw up. I have never looked through an Intes MN61 Mak-Newt but if I was in the market for a planetary scope, it would be on the list to try.
