Easily portable and a joy to use, the Lunt 40 mm joins the Lunt Telescope lineup as our smallest aperture offering, while providing the power, amazing detail and quality you expect from a Lunt Telescope — all at an impressive ~4.0 mm solar image size!

40mm Ha Telescope w/ B500 blocking filer and Helical focuser. Includes SunLock, 4" dovetail, 12mm eyepiece, and Hard case

Standard Kit / Bundle:

Why This Package

Everything you need, nothing you don't. Every component is built to Lunt's standards and works together straight from the case. The front-mounted tilt-tuned etalon delivers full unobstructed aperture performance at 0.35Å — tighter than any competitor at this aperture class. The mini helical focuser provides smooth, precise focus control with a non-rotating design and brass compression ring. The hard case with custom-fit foam protects every component in transit. And like all Lunt 40mm systems, the Standard is fully double-stack capable — add the LS40FHa at any time to bring combined system bandpass to <0.25Å.

Package Includes

  • LS40THa OTA: 40mm aperture, 400mm FL, f/10. Front-mounted tilt-tuned etalon, 0.35Å bandpass. Full unobstructed aperture. Dedicated H-alpha solar telescope.
  • B600 Blocking Filter: 1.25" diagonal housing, 6mm clear aperture. Proprietary filter stack for safe H-alpha observation.
  • Mini Helical Focuser: Non-rotating design. T2 thread connection. 10mm precision travel. Brass compression ring, locking collar.
  • SunLock Solar Finder: Red dot projection onto glass reticle. Internal 3-point alignment screws. Red anodised aluminium.
  • 4" Vixen Dovetail Plate: Black anodised aluminium. Two 1/4-20 tapped holes. Universal mount compatibility.
  • Hard Case: Silver aluminium, 18.5" x 10.5" x 7". Custom-fit foam insert.
  • 12mm Flat-Field Eyepiece: 1.25" barrel. 60° FOV. 5-element design. 0.1% AR coatings. 33x on LS40THa.

Enhanced Kit / bundle:

Why This Package

If you are thinking about solar imaging, or if you simply want the best mechanical performance available for the LS40THa system, this is your package. The CNC-machined rack-and-pinion focuser is a fundamentally different experience from the helical design — smoother travel, positive lock, and the load capacity for any camera or accessory you own. The B600 blocking filter is the right choice for anyone planning to grow — 6mm clear aperture, imaging-ready from day one. And like all Lunt 40mm systems, the Enhanced is fully double-stack capable — add the LS40FHa at any time to bring combined system bandpass to <0.25Å.

Package Includes

  • LS40THa OTA: 40mm aperture, 400mm FL, f/10. Front-mounted tilt-tuned etalon, 0.35Å bandpass. Full unobstructed aperture. Dedicated H-alpha solar telescope.
  • B600 Blocking Filter: 1.25" diagonal housing, 6mm clear aperture. Imaging-ready — expanded aperture for back-focus clearance and reduced vignetting.
  • 1.25" R&P Focuser (1:1): CNC-machined aluminium/brass. 0.5" travel. Rotatable. Integrated brake with variable drag. Brass compression ring. 6–8 lb capacity.
  • SunLock Solar Finder: Red dot projection onto glass reticle. Internal 3-point alignment screws. Red anodised aluminium.
  • 4" Vixen Dovetail Plate: Black anodised aluminium. Two 1/4-20 tapped holes. Universal mount compatibility.
  • Hard Case: Silver aluminium, 18.5" x 10.5" x 7". Custom-fit foam insert.
  • 12mm Flat-Field Eyepiece: 1.25" barrel. 60° FOV. 5-element design. 0.1% AR coatings. 33x on LS40THa.

Premium Kit / Bundle:

Why This Package

The LS40FHa Double Stack filter is included. The 10:1 dual-speed R&P focuser provides the micro-adjustment precision that sub-quarter-angstrom observing demands. The 6" Vixen dovetail provides the extended rail length to balance the system with the DS filter mounted. Every unit is individually assembled, bench-tested, and monochromator-verified before leaving Tucson.
