Bresser Lunt Ls50Tha/B400Pt H-Alpha Solar Telescope Wholesale

A Very Compact, Complete Telescope For Observing The Sun In H-Alpha Light.

The Ls50Tha Solar Telescope Offers 50 Mm Free Aperture, 350 Mm Focal Length, And Provides A Bandwidth Of <0.75 Angstrom. The Telescope Is Fitted As Standard With The Air-Pressure Tuning System "Pressure-Tuner", The Etalon Is Safely Installed Inside The Telescope. Prominences And Surface Detail Can Quickly Be Viewed Spontaneously. This Very Portable System Is An Ideal Travel Companion For Wherever You Go.

A B400 Blocking Filter Is Installed Inside The Star Diagonal. The B400 Is Good For Visual Observing. Focusing Is Achieved By A Non-Roting Helical Focuser.

Please Note That There Is Only A Small Back-Focus At This Telescope, Therefore Solar-Imaging Is Very Difficult. The Ls50Tha Is Designed For Visual Solar Observing. We Recommend For Imaging The 60Mm Telescopes Of The Ls60Mt Series.

Also Double-Stacking With A Bandwidth Of Only <0.5 Angstrom Is Possible By Using The Additional Available Ls50C Filter (0550210). This Filter Threads Directly Onto The Ls50Tha Telescope. Double-Stacking Will Provide Much More Contrast, And More Details On The Sun Will Become Visible.
