SVBONY SV121 Red Laser Collimator Bundle with SV172 Lens Warmer

Introducing our second-generation collimator, SV121, the red laser collimator that perfectly aligns your reflector optics. This collimation eyepiece is designed to precisely collimate Newtonian and Schmidt-Cassegrain reflector telescopes, resulting in better image quality. Worried about dew on your telescope lens during long night photography in winter? Interested in heating a cup of coffee in cold weather? Look no further than our SV172 dew heater strip. Equipped with a universal USB port, this product is convenient to connect to any power source with a USB port, such as a power bank, car charger, laptop, desktop computer, DC power supply, phone charger, or USB wall plug.

The next generation of our product features only one optimal gear position brightness, reducing cumbersome manual adjustment. Additionally, it includes a standard hex wrench for self-calibration of any coaxial problem. The spot shape is a dot instead of a grainy elliptical point, providing a high-end module design. This module utilizes a high-end spherical module for high sensitivity and easy adjustment, as well as a 3-piece glued optical glass lens for stable spotting, better focusing, and less halo.

Should external factors cause off-axis problems during transportation or use, the adjustable collimator allows for self-calibration of any coaxial problem with the standard hexagonal wrench provided. The USB port design includes a 1.8m USB cable length, allowing it to be connected to a power bank or any other power source with a USB port, and accepts 1.9A to 2.0A input current and 5V input voltage.

Our universal lens warmer prevents telescope camera lenses from fogging due to dew by warming up the lens on a camera or telescope. It also doubles as a way to warm up a water bottle and can be used as a wrist or knee strap.
