SVBONY SV197 Collimating Cheshire Eyepiece Bundle with SV233 7PCS Telescope Accessory Kit, 6mm 17mm Eyepiece, 2X Barlow Lens Moon Filter ND4 Filter 82A Color Filter, for Astronomical Observations

This SVBONY seven-piece accessory kit enhances the performance of your telescope. Includes two 1.25" Plossl eyepieces, a 2xBarlow lens that can be used visually or photographically, three eyepiece filter and a Portable bag. Plossl 6mm eyepiece ideal for observing details on planets, the Moon, and other celestial objects. Plossl 17mm eyepiece is suitable for observing a variety of celestial objects, including star clusters, galaxies, nebulae, and even some planetary details. 2X Barlow scope provides 2X magnification for visual observation and astrophotography, magnifying more details of planets, the moon and other celestial bodies, thus enhancing the observation experience. 82A light blue filter. Planetary Observations: Especially beneficial when viewing planets like Saturn or Jupiter, where it aids in highlighting banding and storms. Lunar Observations:Enhances the details of craters and maria on the Moon's surface, providing a clearer view during observations. Moon filter. By decreasing brightness, moon filter improve the contrast between the illuminated and shadowed areas on the Moon's surface. How To Collimate Telescope With SV197 Cheshire Eyepiece: The view through the Cheshire eyepiece during the collimation will differ between telescopes. For fast telescopes (f5 and below), it will be little off-center, and for the slow telescopes (f5 and above), the view will be more centered and easier to collimate. 1.The goal here is to center the primary mirror reflection in the secondary mirror and reflection from the Cheshire with the secondary mirror. 2.To achieve that, you have to use the adjustment screws on the secondary and primary mirrors while looking through the Cheshire eyepiece collimator tool. CNC integrated processing Rugged and durable, prolong the service life of the product.Ensure product high precision. Steel Crosshairs The cross-hair adopts strong and durable steel wire instead of easily broken copper wire or aluminum wire.
