Hmmm, let's see. Have used the TV102 and FS102 side-by-side on planets with GM8/G-11, both equally capable for practical purposes. The NP101 is a wide field Petzval that also is superb on planets. Advantage NP101.
Comparing the NP101 to the 7" Mak is almost apples to oranges, but when cooled and behaving well the Mak's resolving power should prevail under ideal conditions. The TV102 or NP101 will give more consistent performance under varying conditions. 7" Mak has Goto if desired, but also a large thermal to inhibit cooldown. Recommend try before buy!
