I'm thinking about ordering a Lunt LS60THa/B1200CPT and was wondering what's the difference between "tilt" and "pressure" tuned. Thanks again guys!

A tilt tune scope uses a metal pin inside the scope to tilt the etalon, this allows you to tune the filter on band. While this works well you do tend to get banding (this is when part of the view is in tune and the other is not, due to the uneven surface of the etalon).

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.

Well thank you for that information! I'll definitely get the pressure tuned model.

I have the tilt tune and maybe I just got lucky, but with the B1200 I have never been aware of banding and I seem to have no issues with imaging, but I can't speak for the pressure tuned since I have never used one.

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

The Lunt tilt tunes are very good. There is very little banding on them in comparison to other scopes. With a double stack it becomes slightly more apparent. The tilt tune is still an excellent scope.

I have the pressure tuned 60, and we have a club scope that is tilt tuned. My experience is that the pressure tuned scope tends to have a bit more refinement. I would guess that this would but only really noticeable in a side by side comparison, but it is there.

Thanks guys! And Merry Christmas! Since I will be trying my hand at imaging ole Sol, I'll be getting the pressure tuned model. I'm going to order it probably in a week. Wonder how long it'll take for the scope and the clouds to arrive???

Great choice - a PT 60 is a versatile scope and I believe a must have. What camera will you use with it?

Right now just a DSLR Canon T1i. In the future hopefully something better.

If I had the money I would buy a Meade 90MM sun scope for $2500 insteaed of a Lint scope.

Why would you recommend a Meade over a Lunt? It's on sale?

While the Coronado will give better resolution I find the coatings on the Lunts give a superior image.

I've been looking at the Lunt and Coronado scopes online and reading posts here for a while and have decided on the Lunt. It would take something drastic to change my mind at this point. Unfortunately there isn't a club anywhere near here, so I don't have the option of looking through the scopes before I buy. In fact I don't know any one else that even owns a telescope. Wish I did, the learning curve is harder without someone else that has the experience and knowledge to help you along.

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.

Enjoy,,

Another nice feature of the Lunt, is the diagonal has a T-thread, so all you need is a T-adaptor to attach your camera to your scope,nice.

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. :)
