I just received an Intes M715 yesterday. Just finished with my "second light" session. As usual the seeing sucked but this scope pushed through it giving me some nice high contrast views. Anyone into lunar/planetary/multiple star observing and thinking of dropping some long green on a APO refractor should give this scope some serious consideration. The performance is that good shocked

Lets us know how it compares to your STCs. How is
the cool down? Looks like it has vents around the
corrector; maybe a fan in the back? I had a
MK-67 once (6" F12) -- performed about like a
4" APO but took a long time to thermal equalize.

Secondary on the M715 looks small.... How big is the
central obstruction?

I'm writing this just in case anyone was wondering about what kind of performance I'm getting from the 7" F/15 Russian MAK. Since I can't draw well, I've attached a simulated photo that shows what I'm getting at the eyepiece. The color and resolution are exactly the same as what I can see through the scope on an average night. I have yet to have a night of great seeing but the performance of the scope has been stunning. I've looked through a lot of scopes over 30 years and this one stands out in my "top 5" as far as high resolution performance is concerned 8)

I have resolved stars to the diffraction limit with just average seeing (.67"). For me that's impressive for a "CAT" smile

I have also found the light throughput to be quite good. From my home location I can see naked eye to mag 4.2. I have seen stars to mag 12.2 in the scope. This would equate to about mag 14 in an average (6.2 visual) dark sky. Not bad at all smile There must be some truth to the enhanced coatings on the mirrors (95%) and the high transmission multi-coatings on the corrector (96%-97%)

As you can tell, I'm having fun "playing" with my new toy grin
