While discussing the new Celestron M2 Regal spotting scope over in the spotting scope forum I noted a new poster, Optics Camp, who is a fairly local dealer for Celestron. inch length of this model there is plenty of room for my fingers to fit comfortably between the bridges. Levenhuk suggest that these are suitable for children of 4 years and above which is about right, however I know from experience that my daughter was capable of using the very similar Bresser ExploreOne 6x21 Junior Compact Binoculars from around 3 years old.

The compact roof prism binoculars feature a 42 mm lens that lets in sufficient light, allowing you to carry on observing until twilight. As you would expect in a astronomy binocular, all the instruments in this Astro series are tripod adaptable and come supplied with a padded neck strap, a protective carry case, have tethered objective lens covers, rain-guards and a cleaning cloth is also included.

Now that I have this 8x42 model with me, I have the chance to compare them side-by-side and take this thought process a little further and perhaps come to a conclusion.

The cheaper one is based on ordinary glass in the objective lens, the more expensive devices boast low dispersion ED glass.

Gray, matt rubber armour with slightly rough texture sticks well to the chasis, also near objectives. Apart from the slightly smaller carry case, the included accessories and how they function is exactly the same as that of the 8x56 Pirsch ED Binoculars and so I once again ask you to rever to my 8x56 review for details: Accessories for the Bresser Pirsch ED Binoculars.

The Luchs are Bresser's top of the range binoculars that are also known as Bresser Lux Binoculars in some markets. A high quality multilayer coating on all glass elements reduce distracting reflections and improves the light transmission and provides a high contrast also in bad light conditions. The 7x magnification model makes it possible to achieve a relatively steady image during rough sea conditions. This family contains a wide range of binoculars, with 7 models (5 porro prism designs and 2 compact roof prisms).As I was once educated on light transmission curves, manufacturers can customize, to a large extent, which areas of the light spectrum they want to emphasize by selective application of anti-reflective coatings.
