Lunt LS40THa Enhanced Kit - 40mm Dedicated Hydrogen-Alpha Solar Telescope

Lunt LS40THa 40mm H-Alpha Solar Telescope – Enhanced Kit (Solar Ready Bundle)

The Lunt 40mm H-Alpha Telescope is Lunt's most portable dedicated solar telescope. This Enhanced Kit is an ideal grab-and-go hydrogen-alpha Bundle in a 2.6-pound package. Same outstanding Lunt optics. Now with the mechanical precision to capture what you see.

Now with new-generation etalons — every unit individually tested on Lunt's precision metrology equipment. Every specification is verified, not estimated.

The LS40THa Enhanced Kit builds on the Standard with two targeted upgrades for observers ready to explore solar imaging, or who simply want smoother, more precise mechanical performance at the eyepiece.

The B600 blocking filter increases clear aperture from 5mm to 6mm, providing additional back-focus clearance for camera sensors and reducing edge vignetting with larger eyepieces.

The 1.25" rack-and-pinion focuser replaces the helical design with precision CNC-machined components, an integrated brake that eliminates focus drift, and 6–8 lb load capacity for cameras and filter wheels.

What You'll See

The same chromospheric views as the Standard Kit — prominences arcing off the limb, filaments threading across the disk, active regions glowing with magnetic energy — all at 0.35Å verified bandpass through 40mm of full unobstructed aperture.

The difference is in how precisely you can hold and capture those views. The rack-and-pinion focuser with integrated brake means your focus point stays exactly where you set it, whether you are observing visually or attaching a camera.

The B600's larger clear aperture ensures the full image circle reaches your sensor without vignetting.

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.
