Levenhuk Sherman Pro 6.5×32 binoculars review

Levenhuk provided me with interesting binoculars for testing – Levenhuk Sherman Pro 6.5×32. Due to its small magnification and wide field of view (almost 10 degrees), such binoculars can be useful for studying the constellations, for observing landscapes, and also where a stable picture is required with minimal shaking (e.g. sporting events). Declared wide-angle five-lens eyepieces with corrected distortion, fully coating of optical elements, Bak4 prisms, long eye relief and much more.

I got a review of the Pentax ZD 8×43 ED binoculars. I have long wanted to get to know the Pentax Z-series binoculars more closely – I express my deep gratitude to Pentax Russia, who kindly provided me with binoculars for testing. The release of binoculars in this series began in January 2015.

Pentax ZD 8×43 ED

Pentax ZD 8×43 ED uses the most advanced technologies that improve image quality and ease of use in binoculars with Schmidt-Pehan prisms:
– Four-lens lens with ED glass.
-Prisms BK4
– Multi-layer coating of all optical elements to reduce light loss and glare from optical elements.
– Improved coating with the same transmittance for different wavelengths provides a vivid picture without distortion of color reproduction.
– Phase coating (to reduce X-shaped rays around bright point sources and improving contrast) .
– Dielectric coating of prisms (provides a brighter picture with accurate color reproduction compared to aluminum and silver coatings) .
– Hybrid aspheric lens (improves image quality across the field) .
– Hydrophobic coating of lenses (droplets roll better from the lens, reducing fogging from breathing) .
– Moisture protection (binoculars can withstand short-term immersion of 1 meter in water, JIS Grade 6) .
– Nitrogen filling (excludes fogging of the binoculars from the inside) .
– Magnesium case with rubber protection
– Long eye relief (able to observe with glasses).

In late July, I managed to leave for the dark sky in the area of the village of Varenikovskaya. The sky there is really good at its zenith, but from the south there was a noticeable orange flare. I could not resist and again shot a number of hydrogen nebulae – M 16, M 17 and Barnard 312. With auto guide and shutter speeds of 2 minutes, there were practically no defective frames.
