Sky-Watcher Esprit-120ED: opening én precisie
De Sky-Watcher Esprit-120ED is een apochromatisch triplet van 120/840 mm (f/7) met FPL-53-glas. Met 120 mm triplet-opening komen kleinere sterrenstelsels en planetaire nevels fotografisch binnen bereik, terwijl het beeld ook bij hoge vergroting visueel strak blijft. Dit is de maat waarop een Esprit een dubbelfunctie krijgt: topastrograaf én visuele refractor van formaat.
Why an Esprit?
The Esprit line is Sky-Watcher's professional astrophotography series: air-spaced triplets with premium glass, built to place flat, color-pure star fields onto a camera sensor. Stars remain points even in the corners, even with large sensors, and bright stars do not develop a purple halo. This is the class where optics make the difference between a nice and a publishable photo.
Voor de fijnere doelen
Op 840 mm brandpunt vullen bolhopen en compacte nevels de sensor, en de triplet-correctie houdt de sterren ook op grote sensoren strak. De meegeleverde 2 inch star diagonal en zoeker maken visueel gebruik direct mogelijk: planeten door 120 mm kleurzuiver glas zijn een belevenis op zich.
This is how to get the most out of this telescope
- Virtually no cooling time and no collimation: A refractor is ready within fifteen minutes, and the optics stay aligned. More time for photons.
- The setup determines your photo result: een EQ6-klasse montering is het advies: 120 mm triplet met camera is een serieuze last.
- Plan to flatten me: For sharp stars all the way to the corners of your sensor, a field flattener is essential for a photographic refractor. Order it along with your initial purchase to avoid a second waiting period.
- Dew control is essential with lenses: A dew cap or dew heater prevents the front lens from fogging up in the middle of a session.
- Visually pleasing as well: op 140x (met een 6 mm oculair) tonen planeten zich kleurzuiver en gestoken scherp.
- Never look directly at the sun without protection., not even for one photo: only with a certified solar filter in front.

Featured accessories
These accessories add the most after purchase:
- Camera adapter: The Sky-Watcher M48 adapters connect your Canon EOS or Nikon directly to the flattener or focuser.
- Light Pollution Filter (2 inch) Under the Dutch or Belgian sky, a light pollution filter can significantly enhance the contrast in your photos.
