Its large, back-lit 8-line, 21-character display provides comprehensive object data at a glance, while the 9 available slew speeds give you precise pointing control from rapid GoTo slewing to fine centering. Designed for serious field use, the Go2Nova 8407+ features an internal heater, ensuring the LCD remains responsive and readable in temperatures as low as -20°C.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA ~212,000 Object Database on an 8-Line Display\u003c\/h3\u003e\n\u003cp\u003eNavigating the cosmos is faster when you can see more information at once.

Use the MAX speed for quick GoTo slews between targets, then drop to intermediate speeds like 128x or 256x for coarse centering in the finderscope. For final positioning at high magnification, the 1x, 2x, and 8x speeds allow you to place planets or double stars precisely in the center of your eyepiece field of view.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eInternal Heater for Reliable Operation Down to -20°C\u003c\/h3\u003e\n\u003cp\u003eCold weather is the enemy of standard liquid crystal displays, causing them to become sluggish or unreadable. The Go2Nova 8407+ solves this with an integrated internal heater that maintains optimal LCD function in temperatures from 40°C all the way down to a frigid -20°C.
