Compact Barlow Lens and Moon Filter Bundle for Telescope Observers

The SVBONY 1.25" 2x Barlow lens is a superior choice for high magnification on eyepieces, allowing users to see more details of the moon and the bands of Jupiter clearly. The Barlow lens can provide increased magnification without reducing the exit hole on the eyepiece, maintaining a comfortable observation experience with a wide field of view.

This Barlow lens also has the unique feature of being disassemblable, allowing users to remove the black lens portion and integrate it into other possible configurations. For example, when using a 20mm eyepiece on an 80/f5 telescope, the user can achieve 20x magnification. By screwing the bottom lens into the eyepiece, the magnification increases to 30x, and used normally with the eyepiece inside the Barlow, the magnification reaches 40x.

The SVBONY SV139 Telescope ND4 filter is another valuable accessory, as it transmits only 25% of the incoming light, boosting contrast and the ability to discern detail on the moon. Importantly, the filter maintains a perfectly neutral color, preserving the natural appearance of the moon.

This ND4 filter is comfortable to use, helping to reduce overall brightness without altering color, allowing users to see more surface features and details while making their eyes more comfortable. The filter is also easy to match with 1.25-inch eyepieces, as the metal filter cell threads directly into the 1.25-inch barrel.

Constructed with quality aluminum stock and a black anodized body, the SVBONY 2x Barlow lens and ND4 filter are precision-machined for sturdy, long-term use. The Barlow lens has a metal case with a smooth finish and a 1.25-inch interface, doubling the magnification of any 1.25-inch eyepiece. Simply insert the eyepiece into the Barlow lens, then insert the Barlow lens into the telescope.

The ND4 filter, with its 0.6 optical density value and 25% transmission, effectively boosts contrast to discern detail on the moon, without altering the natural color. The standard M28.5*0.6mm threaded design allows easy attachment to the telescope.

The package includes a single SVBONY 2x Barlow lens, two dust covers, a single SVBONY 1.25-inch ND4 filter, and a sturdy plastic case for storage and transport.

In summary, the SVBONY 2x Barlow lens and ND4 filter work in tandem to enhance the viewing experience of celestial objects, especially the moon. The Barlow lens doubles magnification, while the ND4 filter boosts contrast and preserves natural color, providing a comfortable and detailed observation.
