Aperture: 76mm. Focal length: 700mm\u003c\/p\u003e\u003cp\u003eThe Discovery Spark 767 AZ is a classic entry-level Newtonian reflector designed for observing deep-sky objects. With this telescope, you can study double stars, as well as large globular and open star clusters. You can see almost all Messier catalog deep-sky objects, but not in great detail. As for near-Earth objects, you can explore the Moon and the planets of the Earth group.\u003c\/p\u003e\u003cp\u003eThe optics of the Discovery Spark 767 AZ telescope are made of glass with an anti-reflective coating and produce clear and sharp images. The alt-azimuth mount allows you to easily control the telescope by moving the tube both horizontally and vertically. Pointing at astronomical objects is easy to master even for a beginner. The vertical axis of the mount has a locking knob that allows for very precise aiming.\u003c\/p\u003e\u003cp\u003eThree eyepieces and a 2x Barlow lens are included so you can experiment with different magnifications. The adjustable tripod has an accessory tray. Notably, the educational book “Space. Non-empty emptiness” is ideal for all aspiring astronomers and comes in a colorful gift box along with each telescope and other accessories. The book is a guide to space that will help you learn about celestial bodies or refresh your knowledge before continuing with stargazing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey features:\u003c\/strong\u003e\u003cbr\u003eNewtonian reflector with a spherical primary mirror\u003cbr\u003eAlt-azimuth mount with a locking knob\u003cbr\u003eOptics with an anti-reflective coating\u003cbr\u003eRack-and-pinion focuser as well as spare eyepieces\u003cbr\u003eA full-color illustrated guide to the night sky\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe kit includes:\u003c\/strong\u003e\u003cbr\u003eTelescope optical tube\u003cbr\u003eSR 4mm eyepiece\u003cbr\u003eH 12.5mm eyepiece\u003cbr\u003eH 20mm eyepiece\u003cbr\u003e5x24 optical finderscope\u003cbr\u003e2x Barlow lens\u003cbr\u003eAlt-azimuth mount\u003cbr\u003eAluminum tripod with accessory tray\u003cbr\u003eThe educational book “Space.
