Lunt LS40THa Kit Enhanced

LS40THa Enhanced Kit: H-Alpha 40 mm solar telescope optimized for observation and imaging

Visit LS40THa Enhanced Kit takes the renowned optical excellence of Lunt instruments and adds essential mechanical enhancements for demanding astronomers. Designed for H-Alpha solar observing and ready for imaging, this 40 mm telescope combines portability, precision and scalability in a compact format weighing just 2.6 lbs.

Equipped with new-generation standards, each instrument is individually tested using precision metrology equipment. All performances, in particular the 0.35 Å bandwidth, are rigorously verified, guaranteeing consistent, reliable image quality.

A detailed view of the solar chromosphere

The LS40THa Enhanced Kit lets you explore the solar chromosphere in remarkable detail:

• Spectacular protuberances rising above the solar limbus
• Dark filaments running through the disc
• Active regions rich in magnetic activity

With the included 12 mm flat-field eyepiece (33x magnification), you benefit from a sharp, high-contrast image. The major difference lies in its ability to maintain precise focus, ideal for prolonged observation and image capture.

Key improvements for imaging and precision

The Enhanced kit features two major evolutions:

• B600 blocking filter : 6 mm clear aperture, providing more back-focus for sensors and reducing vignetting
• Rack & Pinion eyepiece holder : CNC aluminum/brass design, smooth motion, integrated brake and load capacity from 6 to 8 lbs.

The rotating eyepiece holder allows optimum framing, while the brake system ensures perfect focus retention, even with heavy accessories such as cameras or filter wheels.

A telescope ready to evolve

Like all models in the 40 mm range, this telescope is compatible with a double stack system. The addition of the LS40FHa filter achieves a combined bandwidth of less than 0.25 Å, considerably enhancing the contrast of surface details.

The LS40THa Enhanced Kit is therefore perfectly suited to users wishing to move into advanced solar imaging.
