When selecting a microscope camera, it is best to base your decision on the most important requirements for your microscopic observation. This barlow lens certainly performs well at its main job of doubling the magnification of an eyepiece, and what's more it is also the cheapest in the test.

field of view: with the Orion Nebula in the centre we could fit double star Struve 747 near the edge of the view. Once the measurement has been taken, we are provided with a series of results that show the optical quality of the surface plus other information. ED stands for "extra-low dispersion," which refers to the composition and optical properties of the glass used for the lenses. This Vixen 2x Barlow lens is ideal for observing and photographing lunar landscapes and details on the brighter planets.The soft rubberised material of the dust caps for both barrel and eyepiece holder made for a pleasant change from plastic inserts. The magnification factor of the VIP Barlow at visual use depends on the distance between the top end of the Barlow element and the eyepiece.

With a camera attached for astrophotography - useful when you want to increase magnification or where lack of infocus is a problem. This Barlow gave excellent views of Venus during moments of good seeing despite the planet’s low altitude. Its anti-marring brass compression ring is smooth and the internal micro-baffles, finished in a matt black, complete a well-thought-out design.This is a good thing, because normally the shorter the focal length of the eyepiece, the less eye relief you have. It has a middling weight of the lenses reviewed at 165g, and the body is elegantly designed, with a silver undercut lens barrel and chunky rubber grip. Great lens Spoke to the sales guys about which scope would be best for planetary exposure and they recommended this one. In the 1960s, Celestron’s founder, Tom Johnson, created groundbreaking new telescopes never before seen on the consumer market. The lens itself unscrews from the housing, looking forward to seeing if I can use it with a t adapter to achieve prime focus with my dslr.

Now, Celestron is using that same technology to allow star gazers to connect to the night sky and enhance their experience of the cosmos in fun and unique ways. Within the interferometer is a calibrated laser that is pointed through the optical test surface, then onto a high quality reference sphere, then back through the test subject then to an internal camera which gives us the measurement on the screen. More than 15,000 Baader planetariums (the company’s first patented product) help students around the world to understand astronomical relationships.Not so good with my higher power BST StarGuider eyepiece but this may be down to the seeing conditions. Insert the Barlow lens between the eyepiece and the telescope and you will double the magnification. Get ready for a night of astroimaging with your mount faster than previously thought possible with All-Star Polar Alignment. Typical Barlows have a magnification of 2x and are composed of two or sometimes three elements in a single group, forming a negative lens.

This innovative software solves the time-consuming problem of trying to pinpoint the North Celestial Pole. This design ensures that the original eye relief of the eyepiece remains unchanged, making it more suitable for longer focal length eyepieces and avoiding the risk of vignetting.Once the Zygo test report has been completed, the optical alignment is thoroughly tested and tuned to ensure they are spot on before they leave us. The green-tinged multicoating on the lens surfaces was evenly applied and micro-baffles were easily visible within. This three-element multicoated design places the lower lens element at the very base of the barrel, meaning it does not include a filter thread. U nleash the full pointing accuracy of your Celestron computerized telescope with a specialized telescope control software suite.
