iOptron HEM27EC Montering GoTo: hybride precisiemontering met RA-encoder
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).
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.
Voorbereid op de iPolar elektronische poolzoeker, die als accessoire is toe te voegen.
Real-time error correction on the RA axis
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.
For long brand point-to-point distances, the ST-4 port remains available.
Hybrid drive without counterweight
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.
The electronic friction brake safely stops the mount during a power failure, and the power-down memory preserves position and alignment.
Complete control
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.
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.
Included
- HEM27EC monteringskop met RA-encoder
- Go2Nova 8409 Hand Controller
- Transport bag
- Power supply and USB cable
Featured accessories
Expand the mount with the iPolar for SkyHunter and HEM27 for electronic polar alignment, and the HEM27 counterweight shaft for heavier setups.
For whom yes and for whom no
- ✓ Astrofotografen die zonder guiding lange belichtingen willen maken
- ✓ Wie de hoogste precisie in een reismontering zoekt
- ✗ Wie de encoder niet nodig heeft: de HEM27 met iPolar is voordeliger
