iOptron Go2Nova® 8407+ Hand Controller
- ~212,000 Object GoTo Database
- Large 8-line, 21-character backlit LCD screen
- 9 slew speeds for precise centering
- Internal heater for operation down to -20°C
The iOptron Go2Nova® 8407+ Hand Controller puts a massive ~212,000 object database at your fingertips. 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.
Navigating the cosmos is faster when you can see more information at once. The Go2Nova 8407+ handset's 8-line display shows significantly more data than typical 2-line controllers, reducing the need to scroll through menus to confirm coordinates or object details. The ~212,000 object database puts a wide choice of targets a few key presses away.
The Go2Nova 8407+ gives you granular control over your mount's movement with 9 distinct speeds. 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.
Cold 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 at temperatures as low as -20°C. This makes the 8407+ a critical upgrade for astronomers who observe year-round in cold climates, ensuring your GoTo system remains your most reliable tool on a clear winter night.
The Go2Nova 8407+ is the standard controller for many modern iOptron GoTo mounts. It serves as a direct replacement or upgrade for compatible systems. Always consult your specific mount's documentation to confirm handset compatibility before purchasing.
The larger display shows more object data simultaneously, such as coordinates, magnitude, and size, without forcing you to scroll through multiple screens. This allows you to quickly verify that you are targeting the correct object and celestial coordinates before initiating a slew, which is especially helpful for large, faint targets or crowded star fields.
The internal heater prevents the back-lit 8-line LCD screen from freezing, slowing down, or becoming unreadable in cold weather. This ensures reliable and responsive operation in temperatures down to -20°C, making it an essential tool for observers in northern latitudes or at high altitudes.
After the initial GoTo slew, use the medium speeds (e.g., 64x or 128x) to bring the planet into the center of the field. For precise final positioning to study features like the Great Red Spot or individual Galilean moons, switch to the slowest speeds (1x, 2x, or 8x) for fine, controlled adjustments without overshooting your target.
The Go2Nova 8407+ has its own RS232 serial port for hand controller firmware upgrades. Connect the handset to a PC with an RS232 to RJ9 serial cable and use the appropriate iOptron firmware upgrade utility, which can be downloaded from the iOptron website.
Yes. The database contains a comprehensive catalog of stars for alignment procedures in addition to a vast collection of deep-sky objects (Messier, NGC, IC), planets, the Moon, and the Sun (with a proper solar filter).
