I also have little information on the new 8 inch Cassegrain hydrogen alpha scope. First you'll be able to buy it as a fully assembled scope or you can send your scope to them. They will install a threaded adapter on the front of your scope.
This system incorporates to filters on the front of your scope both threaded on individually and are stacked one on top of the other. I think one was an energy rejection filter and the other a UV filter but I'm not sure. The heart of the system goes on the back of scope. It incorporates a couple of collimation lenses and that heated etalon(that heats to 180°), and a blocking filter. This setup is custom-made for any scope and does not change the focal length of your scope. If you want to change your set up to a different scope. Just the collimation lenses would have to be changed. This is still a few months away and prices not set. If the Sun only came out today. They were going to set it up outside. I will add a picture of the scope.
