2x achromatic Barlow lens with with T2 Thread and comression ring, Fully multi-coated Glass and All metal design, 2-element lens
For 1.25″ eyepieces and telescopes with 1.25″, Clear Aperture: 23mm
Just insert the Barlow lens between the eyepiece and the telescope and you will double the magnification. At the same time you will retain the comfortable eye relief of the longer focal length eyepiece.
blackened lens edges result in optimum contrast and image sharpness.
This 2x Barlow Lens can be used both visually and photographically. For visual use it accepts 1.25″ eyepieces with a resulting magnification factor of 2x. For this application the Barlow works the same way like any other Barlow lens.
The Integrated T2 Thread The special feature of this Barlow lens is its integrated T2 (M42x0.75) thread which allows it to be used photographically. For example you can screw it directly into the T-ring of your DSLR camera. The resulting magnification factor for this use is 2.5x. This of course works also with other cameras with T2 thread, but the factor may be different, depending on the distance between the Barlow lens element and the camera’s sensor.
This fifteen-piece 1.25 inch astronomy accessory kit let you get the most out and enhances the performance of your telescope. It is a great save compared to buying items separately
6mm/8mm/12.5mm/ 20mm/40mm Multi-Coated plossl eyepiece–for different power planetary and lunar observation broad-field lunar observations, star clusters, and a wide range of cloudy nebulas and deep-sky target, as well as daytime use in any telescope.
5 color planetary filters — The five color filters (Red, Blue, Orange, Green＆Yellow) and a polarizing filter highlight features on Mars, Jupiter, and Saturn. They are an essential tool of the lunar and planetary observer, for filters permit the observation and photography of surface detail that is often virtually invisible without filtration. Moon filter — helps to dim the bright light from the Moon, making it more comfortable to view so you can see more detail and surface features.
2X Multi-Coated Barlow lens — A visual Barlow, doubles the magnification of any inserted 1.25 inch eyepiece, A prime focus T-adapter for attaching a DSLR camera. With the T2 threads (M42x0.75), you can attach a T-ring for astronomy photography. A tele-extender for increasing the focal length of the telescope when attaching a DSLR camera.
An Accessory Case (Silver)–not only does it hold up all the accessories, but also with extra space for another two eyepieces, a laser pointer, a diagonal or other small accessories.
The 1.25″ Eyepiece and Filter Kit is a great starting kit for anyone getting their first instrument or for anyone looking for a good accessories base on which to build on. The astute astronomer will recognise the terrific value offered in this kit: the eyepieces range is better suited to the average astronomer than similar eyepieces and filters kits from other (famous) brands: indeed the selection of focal lenghts delivers increased versatility by reducing the low focal lenghts eyepieces. The low focal lentghs eyepieces are often promoted as a good option delivering high magnifications: if it is true the magnification is higher, it is always at the cost of image quality and sharpness and in practice simply less useful and enjoyable. The kit includes in the aluminium, foam-lined, carry case the following:
