Pressure tune uses air pressure to the tune the etalon. There are no physical movements happening to the glass and even thing is kept even. This provides an excellent illuminated surface with no banding issues.
If you plan to on doing imaging I recommend the pressure tune model. These also seem to have finer control while tuning the etalon. The tilt tune works fine but for a bit more the pressure tuner is worth it.

You can view what can be imaged with the tilt tune LS60 on my Astrobin site in my signature.

Right now just a DSLR Canon T1i. In the future hopefully something better.
It doesn't have to be better camera, but a monochrome camera will likely give you much better results with an H-a scope. The color Bayern matrix sensor does funny stuff with that narrow single band light.

If I had the money I would buy a Meade 90MM sun scope for $2500 insteaed of a Lint scope.
The Coronado 90's are a fine scope and built like a Tank. I really got a ton of use out of mine. I never could get past that helical focuser though. It's a bit dated by todays dual speed focuser standards (and I think Moonlite focuser has come up with a replacement for it). But still the build of the scope makes me think more of it like a Mac vs PC where the Coronado is the Mac. For a 90mm scope it weighs in much too heavy for a CG-4 type tripod and requires the next higher brawn of a CG-5 at least. Its a great scope though.
