Congratulations, you have just managed to defy the laws of physics.

This is an interesting article and comparison conducted by Ed Ting a few years ago. Note the Mak in this review is an Intes MN61 (6" Mak newt) which will outperform a similar aperture MCT due to the fact it has a smaller central obstruction (18% Vs over 30%) and one less reflective surface (diagonal)
