Field of View: 40°/Focal Length: 12.5mm
Plossl eyepiece with red LED-illuminated double-line cross-hair reticle and high-contrast views with a 40-degree apparent field of view, excellent for accurate polar and go-to alignment and for centering guide stars for astrophotography. The 12.5mm eyepiece focal length and the 11mm eye relief ensure comfortable observation experiences.
Illumination Adjustable
The crosshair illumination is variable over a very wide range, available to adjust the illumination according to various observation needs. The double-line cross hairs are narrow and well defined, which helps best with precision. The eyepiece is powered by 3 cell batteries and when running out they are easy to get in the local store
Standard 1.25-inch
The interface is standard 1.25-inch so that this is available to attach to standard 1.25-inch guiding scope.

off-axis guiders or guide scopes; The illuminated crosshairs eyepiece is
precisely located in the center of the eyepiece field of view;
providing accurate results that allow you to easily track the guide The SV152 crosshair eyepiece have a wide 70-degree apparent field of
view makes acquiring and centering target objects a breeze; comfortable
16mm eye relief So you do not have to worry about the goal disappearing
quickly This SV152 illuminated single crosshair eyepiece has a brightness
adjustable function; which has relatively low energy consumption at
lower brightness; which can extend the life of the illuminator; with a
crosshair for illumination Perfectly guided astrophotos; The crosshairs for easier use and
alignment; excellent for accurate polar and go-to alignment; Fully multi
coated broadband green optics with superior optical performance;
clarity is great
SWA (Super Wide Angle) 70°/Focal Length: 20mm
The illuminated 1.25” 20mm reticle eyepiece with a 70°apparent field of view, is designed for refining the alignment and pointing accuracy of your goto telescope, helping to find your target star easily and do very precise centering of the alignment stars. And reticle eyepiece is essential for precise polar alignment when doing long exposure astrophotography.
Ensuring High Transmittance
The five-element optical system is fully multi-coated on all air-to-glass surfaces with high transmission anti-reflection coatings, allowing greater optical through-put across the entire visible light spectrum, for bright, crisp views. The edges and the inner wall of the lenses are blackened for high contrast.
Illumination Adjustable
The crosshair illumination is variable over a very wide range, and gets quite dim at the lower end, so that dimmer stars may be seen. They are also bright enough to use in daylight at the upper end of the range. The crosshairs are narrow and well defined, which helps with precision. The eyepiece is powered by 2 cell batteries and they are easy to get in the local store when running out.
1.25-inch & M28.5*0.6
The interface is standard 1.25-inch so that it is available to attach to standard 1.25-inch guiding scope. The M28.5*0.6 threads are for standard 1.25-inch filter.
This eyepiece for the following applications: - setting the exact alignment of the telescope and finder - polar alignment (by drift method) - an invaluable aid to centering guide stars and astrophotography target objects - the perfect eyepiece for alignment of computerized GoTo systems
