This Barlow lens doubles the focal length of your telescope. It allows you to make astronomical observations with a higher magnification than a conventional eyepiece. Thanks to the Barlow lens between the eyepiece, you can obtain a greater magnification whilst maintaining a comfortable interpupillary distance. This Vixen 2x Barlow lens is ideal for observing and photographing lunar landscapes and details on the brighter planets. The Barlow lens also features a T2 connection for photography with DSLR cameras. With T2 extension tubes, it can also be used as a camera projection adapter. With a deflecting prism, the Barlow lens enables you to obtain a magnification factor of 3.3x.     FEATURES 2x Barlow lenses with T2 thread 2-lens optical system Doubles the magnification factor Also suitable as a camera adapter 31.7 mm sleeve Weight: 80 g   DELIVERY CONTENT  2x Barlow lenses Dust caps

This 2-power nose piece Barlow makes it easier to focus with most telescope. It can be screwed onto 1.25" eyepieces as well as binoviewers. For even more magnification, it can be placed after the optional binoviewer extender.

Xtar 16340 Rechargeable Li-ion battery with 650mAh capacity. Electronically protected against overcharging, over-discharge, overload and short-circuit.

2 independent charging channels Processor-controlled three-stage charging process TC/CC/CV High charging current- 2X 2a/3X 1a Powered by any micro USB Charger (recommended WITH QC 3.0) Compact size-Easy to carry Reactivation function of deeply discharged cells Protection: Short-circuit, thermal, reverse polarity In a small enclosure, a fully professional processor loader with a three-stage charging process TC/CC/CVis concealed. It loads 3.6/3, 7V Li-ion cells with any capacity in sizes 18650, 18700, 20700, 21700, 22650, 25500, 26650.What Is THE TC/CC/CV charging method? It is a three-step process of loading Li-ion cells to keep the cell in good condition by charging the right current at each stage and completing the charging process at the right moment.The various stages of the TC/CC/CV process are:• TC phase: Cells discharged below 2, 9V are ’ awake ’ to lower currents.• CC phase: When 2, 9V is reached, the cell is loaded with a constant current of 2x2A/1x3A.• CV phase: When the cell is already nearly charged, the charger switches to a decreasing current charge until it reaches a voltage of 4, 2V on the cell. After reaching 4, 2V the charging process is complete-the battery is fully charged.Batteries with a voltage of 4, 1V or higher are treated by the charger as charged. To recharge such a full battery, please insert it into the charger before powering it in. When left in the charger, the charged batteries will be subjected to a natural self-discharge process. Charging will resume when the battery voltage drops below 4, 1V.The Xtar SC2 Charger has a function of reactivating deeply discharged cells and cells with a Voltage Of 0v. Many chargers on the market are not able to charge such batteries. Here with the help comes the charger Xtar SC2, which in many cases allows you to ’ resave ’ such cells. Just insert a deeply discharged battery into the SC2 charger, as with normal charging, the charger detects the unloaded link and attempts to reactivate it. Attention! Cells unloaded below a certain level are irreversible and reactivated may not be possible. Avoid too deep discharge of Li-ion batteries-this can lead to a significant reduction in their durability and capacity or to their total malfunction.Chargers from other manufacturers can significantly increase the temperature of the cells being charged during charging. Excessive heating of the cells can cause them to wear more quickly. When designing a SC2 charger, Xtar went one step further from the competition, solving this problem easily: the power from an external power supply was applied. This allows the temperature of the SC2 rechargeable battery to increase by up to 15 degrees.Supplied with Xtar SC2 charger, we get a micro USB cable. The power supply is not Included In the set. Any charger with a micro USB cable, for example, is enough to power the charger. Phone, or USB port or a computer with a free USB socket. The recommended minimum charger power is 2A).

Vintage desk bar globe on antiqued finish stand and classic ebony map. With its wonderful illustrations of sea monsters, mermaids and mythological figures, Sfera 42 globe can carry 2 or 3 bottles and approximately 9 glasses. Thanks to the North and South meridians, the sphere fully rotates around them either when opened or closed.Diameter: 42cm Height: 57cm Width: 42cm Style: ClassicFlorence, the art city par excellence, is where the Tre-Esse brand comes to life. Selected waxed wood and accurate processing make each piece a timeless classic. Each object is exclusive and unrepeatable...all this, combined with the Made in Italy craftsmanship, makes our collection of globes as unique as a signature:Tre-Esse Firenze.

The new desk bar globe Galileo is a fine example of Italian craftsmanship. Based on a hand-drawn 18th century map, the Galileo bar globe is ideal for limited floor space or as an alternative to the classic floor-standing bar globe. A standard globe drinks cabinet model with a chestnut stained wooden base. It holds 2/3 bottles and up to 9 glasses."The sun, with all those planets revolving around it and dependent on it, can still ripen a bunch of grapes as if it had nothing else in the universe to do." (Galileo Galilei)
