The accessory kit contains: A 12.5 mm - 1.25" eyepiece: increases power up to 24x, making objects requiring more magnification easier to find and observe. A 6 mm - 1.25" eyepiece: This eyepiece increases power up to 50x, which increases the magnification factor and provides more detail accuracy to fuzzy objects. A moon filter - 1.25": A moon filter reduces the moon's brightness and improves contrast to observe more details on the moon's surface. The screw thread on the filter allows it to be screwed onto the lower part of the eyepieces. A 5x24 Finderscope and a support batten: This finderscope with support batten makes it easier to locate astronomical objects, thanks to its wider field of view and lower magnification. No additional tools are required for installation. A nylon carrying bag for the FirstScope: Pack your FirstScope and accessories in this large bag for easy and safe transport.
