The Barlow is simply placed in your focuser or star diagonal before the eyepiece and will suit virtually any telescope that accepts 1. It is easy to use; insert the eyepiece into the Barlow lens, then insert the Barlow lens into the scope. Unlike traditional telescopes, the RASA design ingeniously places the imaging sensor at the front of the telescope tube, creating an ultra-fast f/2.

When selecting a microscope camera, it is best to base your decision on the most important requirements for your microscopic observation.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. There is no anti-marring compression ring, although, depending on your eyepiece barrel type, this may be considered as an advantage.

Just point the telescope at any three bright objects—stars, bright planets, or even the Moon—and your telescope can orient itself with the night sky. SKYWATCHER 2X DE-LUXE ACHROMATIC BARLOW LENS Purchased this item on recommendation of Harrisons after enquiring what I would need to attach my mirrorless camera to my scope.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. Named after English physicist and mathematician Peter Barlow, Barlow lenses add a second lot of magnification to each of your eyepieces while maintaining the existing eye relief. Due to their two lens design, these Barlow lenses provide a brilliant image quality for the whole visual field and are suitable for observations and photography. It is elegantly designed with a conical top and a tapered lens barrel for secure attachment, and its centre is neatly wrapped with a simple patterned rubber grip to make it safe to handle even when wearing gloves. Both Barlow lenses and Powermates act as image amplifiers by increasing the effective focal length of your telescope, thereby increasing the magnification achieved with any eyepiece.

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. The removed Barlow lens cell can be screwed directly to any eyepiece, imaging camera or webcam fitted with a 1.use the T-Adapter with the barlow lens along with a relevant T2 mount (not included) for tele extended photography.

You calculate the magnification of a telescope by dividing its focal length by the focal length of the eyepiece. A Powermate is a telecentric design with four lenses in two doublet groups: a smaller negative lens and a larger positive lens arranged so that light exits the Powermate in parallel rays. It incorporates high quality optics with apochromatic characteristics, for magnifications of 2x and above.The lower lens housing is threaded to accept standard filters and the screw for holding the eyepiece doesn't unscrew the whole way, meaning it shouldn't fall out and get lost in the dark. Really easy to use, it fits onto the eyepiece and is a less expensive way of increasing a telescopes magnification.
