• AstroSolar® ECO-size Safety Film 5.0 for solar observation and photography at high magnification
• Size: ca. 140 x 155 mm, incl. DIY-instructions and DIY cutting-template – telescope quality – Optical Density (OD) = 5.0
• Safe for visual solar observation (with additional optics) and imaging
• This highest precision film consistently produces strehl ratios of 94 to 96 percent at interferometric tests – thus it performs optically like a Fluorite Triplet Lens by Carl Zeiss or Astro Physics
• For more than 25 years on the market, the only film-material made to not deteriorate the optical wavefront, it does allow to attain high magnification with any long-range optics without reducing sharpness or contrast of the solar surface.
• The film is from the same material as our proven AstroSolar® Safety Filme 5.0 in A4-size, due to high demand now availble in a smaller size at an economical price, suitable as solar filter for small telescopes, finders, binoculars, spotting scopes and camera lenses

• This highest precision film consistently produces strehl ratios of 94 to 96 percent at interferometric tests – thus it performs optically like a Fluorite Triplet Lens by Carl Zeiss or Astro Physics
• AstroSolar Safety Film is best suited for precision work with all astronomical telescopes and binoculars – just as well as for all photographic camera- and tele-lenses

• The Celestron 2.5x Luminos Barlow increases the magnification of any 2” or 1.25” eyepiece by two and a half times
• High-quality 4-element optics produce a flat field for sharp images that are free of extraneous color
• Hard-anodized aluminum barrel is threaded to accept 2” filters
• A brass compression ring holds eyepieces firmly in place, and large thumbscrews are easy to turn, even with gloves on
• A 2” to 1.25” adapter is included.  Allows the use of both 2” and 1.25” eyepieces.

Ideal entry-level model with output of linear and equivalent horizontal range (EHR) from 10m to 1,100m / 1,200yds
High-precision rangefinding up to 1,800m / 2,000yds
Outstanding, easy-to-read LED display with automatic brightness control
Brilliant, clear image, high level of detail – even at twilight

The new TECHNO STABI 12X28 Compact Binoculars provide outstanding performance while combining high power, stabilization and exceptional views with durability, all in a compact body.

FUJINON TECHNO STABI 12X28 Key Features:

• Equipped with vibration canceler; vibration correction range of ±3° delivers stable images with 12x magnification.
• Fully multi-coated optics and phase-coated prisms provide sharp, high contrast images and bright view.
• Battery can run for up to 12 hours; auto off function turns power off after 10 minutes 
• Precise center focus wheel for easily bringing details into sharp focus
• Made of fiberglass-reinforced, high durability plastic 
• Lightweight, compact and ergonomic weighing only 0.93lb

The TSRCKOLLI collimator was developed for Ritchey-Chrétien telescopes, but also for all other types of telescopes, like refractor, Newtonian or SC Cassegrains - made in Europe

• The corrector allows the collimation of almost all optical systems with high accuracy.
• Suitable for all 2" receptacle with precice 2" barrel to avoid tilting
• LEDs are powered by 2 normal 1.5V AA batteries (batteries are not included)
• We recommend the collimator mainly for RC telescopes, Cassegrains and Schmidt Cassegrains as long as they have a center mark on their secondary mirror. So a top collimation state of the telescope can be reached even at daylight.

The adapter extends a male T2 thread to M48x0.75 (2") filter thread without increasing the length.

• Female thread: T2 - M42x0.75
• Male thread: 2" filter thread - M48x0.75
• Length: only 2.5 mm - the mechanical length is optically not effective, as the adapter is completely sunken in the connection adapter
