JOIN THE SOLAR PHOTOGRAPHY REVOLUTION

Introducing the SOLEYE 300 Dualband professional solar telescope

Explore the Sun like never before, enabled by our innovative telescope design.

The SOLEYE 300 is engineered for the dedicated solar photographer. It provides an unprecedented opportunity for creating stunning photos of the Sun, the celestial body that powers our planet.

The SOLEYE 300 confidently tackles the unique challenges of solar photography

Robust & straightforward design, making it uncomplicated to use while also getting excellent results. Lightweight, easy to carry and set up. Innovative features to avoid heat damage and deformation.

High-resolution
solar photography
even in Ca-K and H-alpha

Thanks to a completely unique, world-first SOLEYE coating with high surface accuracy, the primary mirror has extremely low heat absorption and zero thermal expansion, making it the optically best performing primary in the medium size category in continuum, Ca-K and H-alpha high-resolution solar photography as well.

The SOLEYE 300 is a hand-built, medium-sized, highly precise solar telescope with exceptional quality special coated energy rejecting primary mirror.

The components are sourced from 3 different continents. This makes it a unique product with a reasonably long manufacturing process, making it a truly exclusive piece of hardware with very limited accessibility.

The New Standard of Clarity, Proven

An instrument is ultimately defined by the images it can produce. Below is a selection of images captured with the SOLEYE 300, showcasing the uncompromised clarity and breathtaking detail that is possible.

SOLEYE 300 Technical Specifications

Reflecting Solar Telescope

300/1200 F/4 Newtonian reflecting solar telescope for high-resolution Chromosphere and Photosphere imaging

OTA with portable dimensions: 1110 mm long and weighing 14.5 kg

More than 60 bespoke design CNC machined parts, high strength carbon elements

CryoSol Passive space-tech Thermal Control System installed on OTA

Main frame

Ultralight asymmetric double octahedron carbon truss tube

Zero thermal expansion allows stable focus for hours in changing temperature

Minimised sunlit surface and self cooling geometry on main CNC parts

Vixen plate included (can be supplemented with Losmandy adapter)

Dielectric Dual-Band Primary ERM Mirror

Unique high quality dielectric coated ERM “energy rejection” mirror technology

Very little energy to be focused on the camera side

Rejects almost all incoming energy except in H-alpha and Calcium range

Designed for Chromosphere observation in H-alpha and Ca-K/H and for continuum (whitelight) observation in red, blue and NUV. It provides enough light for your etalons.

Market leader 0,46” resolution possible in H-alpha

World leader 0,24”/0,28” resolution possible in NUV – only with SOLEYE technology.

Strehl ratio 0.95 (excellent) or better

Outstanding coating surface accuracy of +- 5 nm over the entire 300 mm mirror

Available in two versions:
1. ‘SOLEYE Dualband’ for H-alpha, Ca-K/H and for red/blue continuum.
2. ‘SOLEYE Violet’ for pioneers optimized for G-band and Ca-K/H and UV spectral ranges, making even UV solar high resolution photography possible.

“Air Knife” Primary Cell

Cell with 6 No. supporting points to minimise primary deformation

No cell parts over the mirror surface – natural laminar flow is enabled, eliminating any chance of mirror-seeing

Secondary Mirror

Minor axis 78 mm, quality: L/18, 96% reflectivity

Ultra stable 6 No. stainless steel legs (in 3 groups)

Optional edition with gold plated legs for extra thermal reflectance

Internal ERF Filter

Dualband ERF Filter for H-alpha and Ca-K/Ca-H

20/25 nm halfband width

Focuser

Ultraprecise silver design Primalucelab ESATTO 2″ robotic focuser ‘SOLEYE edition’

Robust and smart: it can support your telecentric barlow and double stack H-alpha etalon system

Optional self cooling camera adapter and corrector

Self cooling camera adapter and coma correcting barlow lens for whitelight imaging with 3-6 magnification factor for all pixel sizes

Quark adapter kit to install your quark in the fastest way

Adapter and correction lens kit compatible with Baader telecentric systems

Optional instrument console

For Finder, SSM and Guider
