iOptron HEM27EC Montering GoTo: hybride precisiemontering met RA-encoder<\/strong><\/h2>\n\n\n\n

The iOptron HEM27 is a hybrid equatorial mount: strain wave drive on the right ascension axis, backlash-free worm and belt drive on the declination axis. Without a counterweight, it carries 13.5 kg (29.7 lbs) with a head weight of only 3.7 kg (8.15 lbs).<\/p>\n\n\n\n

De EC-uitvoering meet de rechteklimmingsas met een hoge-resolutie encoder en corrigeert de periodieke fout in realtime (RPEC). Bij korte en middellange brandpuntsafstanden fotografeer je daarmee zonder autoguiding.<\/p>\n\n\n\n

Voorbereid op de iPolar elektronische poolzoeker, die als accessoire is toe te voegen.<\/p>\n\n\n\n

Real-time error correction on the RA axis<\/strong><\/h4>\n\n\n\n

De encoder stuurt continu bij, precies waar strain wave aandrijvingen het nodig hebben. Strakke sterren in lange onbewaakte belichtingen, zonder guidescope, guidingcamera en extra kabels.<\/p>\n\n\n\n

For long brand point-to-point distances, the ST-4 port remains available.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Hybrid drive without counterweight<\/strong><\/h4>\n\n\n\n

The combination of strain wave on RA and worm\/belt on declination provides the load capacity of a harmonic drive with the refined tracking behavior of a traditional drive. A counterweight is unnecessary in most setups.<\/p>\n\n\n\n

The electronic friction brake safely stops the mount during a power failure, and the power-down memory preserves position and alignment.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Complete control<\/strong><\/h4>\n\n\n\n

The Go2Nova 8409 hand controller contains over 200,000 objects; Wi-Fi is routed through the hand controller, and computer control is possible via ASCOM, INDI, or iOptron Commander. Autoguiding via the ST-4 port and PEC correction are built-in.<\/p>\n\n\n\n

The internal cable management and the dual Vixen\/Losmandy-D saddle keep the photo setup tidy; the built-in zero-position finder automatically finds the starting position.<\/p>\n<\/div>\n<\/div>\n\n\n\n
