Yes this is definiatley an amazing layout!!! I dont know a single amateur using a beam splitter for multispectral imaging, these guys are using SIX on one beam... I do have a real nice 2" beam splitter cube, maybe ill put it to use.

They have amazing seeing conditions, I need to move there :)

This telescope vacuum tube and adaptive optics which uses real time wave front analyzer with closed loop. Therefore after the seeing reaches a certain level (say, 1,5") then the AO makes the image literally diffraction limited for such an aperture.
Without an AO you still need a lucky imaging technique (LIT). In general, if a local seeing is OK, then LIT can deliver the same level of detalization as an AO. LIT is a like "post-factum AO". If an AO corrects wave front defomations, the LIT just rejects too distorted image fragments.
"Solar H alpha activity is the most dynamic and compelling thing you can see in a telescope, so spend accordingly." (c) Bob Yoesle.
