Lunt 50mm Telescope Bundle

The Lunt 50 mm Dedicated Hydrogen-Alpha Solar Telescope, complete with a Pressure Tuner, provides the basic essentials perfect for a first time introduction to solar observing. Also it includes the newest technology for fine tuning, allowing basic research of the Sun’s disk and some surface details.

EXTENDED SHIPPING TIME:  Lunt Telescopes are individually assembled and tested by hand.  Allow up to 90 days for assembly.  These telescopes are well worth the wait!

DISCLAIMER:  Because this is a "built to order" item, no returns are accepted outside of manufacturer defects.

Standard Kit / Bundle:

Why This Package

Everything you need. Nothing you don't. Ready to observe straight from the case. The LS50THa Standard is your fastest path to pressure-tuned hydrogen-alpha observing. The integrated clamshell base means setup takes minutes. The helical focuser provides smooth, precise focus control. Unpack, mount, and you are watching the chromosphere. And like all Lunt 50mm systems, the Standard is fully double-stack capable — add the new-generation LS50C at any time to bring combined system bandpass to ~0.30Å.

Enhanced Kit / Bundle:

Why This Package

This is the package for the observer who has caught the solar bug and wants to go deeper. The rack-and-pinion focuser is a permanent upgrade to your observing experience — once you feel the difference in mechanical precision, you will not want to go back. Three dedicated solar eyepieces mean you always have the right magnification without compromise. And like all Lunt 50mm systems, the Enhanced is fully double-stack capable — add the new-generation LS50C at any time to bring combined system bandpass to ~0.30Å.

Package Includes

• LS50THa OTA w/ Clamshell: 50mm aperture, 350mm FL, f/7. Internal pressure-tuned etalon (Doppler True), 0.6Å bandpass. Unobstructed aperture. Integrated clamshell mounting base.

Premium Bundle / Kit:

Why This Package

The LS50C Compact Double Stack filter is included. The simplicity of the LS50C attachment is one of its most compelling features — threads onto the OTA front like a filter, installed in seconds, removed just as quickly. The 6" Vixen dovetail provides the extended rail length to balance the system with the DS filter in place. The 1.25" rack-and-pinion focuser with integrated brake delivers the mechanical precision that narrow-bandpass observing and imaging demand.

Package Includes

• LS50THa OTA w/ Clamshell: 50mm aperture, 350mm FL, f/7. Internal pressure-tuned etalon (Doppler True), 0.6Å bandpass. Unobstructed aperture. Integrated clamshell mounting base.
• LS50C Compact Double Stack: New-generation etalon. Threads directly onto front of OTA — no tools required. Combined system bandpass ~0.30Å — LS50C (0.35Å) + internal PT (0.6Å) in series.
• B600 Blocking Filter: 6mm clear aperture, 1.25" diagonal. Imaging capable.
• 1.25" Lunt R&P Focuser (1:1): CNC-machined aluminium/brass. 0.5" travel. Integrated brake with variable drag. 6–8 lb capacity.
• SunLock Solar Finder: Attaches to clamshell. Red dot projection onto glass reticle.
• 6" Vixen Dovetail: Extended rail for balanced mounting with double-stack filter. Black anodised aluminium.
• 7.2–21.5mm Zoom Eyepiece: 7 elements/4 groups. 0.1% AR coatings. 15mm eye relief. 53°–40° FOV. Near-parfocal.
