Sky-Watcher Explorer-300PDS – 305/1500 Imaging Newtonian Reflector

Sky-Watcher Explorer-300PDS (OTA): het imaging-topmodel

De Sky-Watcher Explorer-300PDS is het topmodel van de imaging-lijn: een 305/1500 mm Newton (f/4,9) met een enorme parabolische spiegel. Twaalf inch resolutie en lichtopbrengst voor wie fotografisch het onderste uit de kan wil, en visueel een instrument van observatoriumkaliber. De buis weegt 23 kg: dit is een project, en dat hoort zo.

What can you do with it?

Photographically, this is the class where smaller galaxies, planetary nebulae, and fine structures become accessible: lots of aperture, lots of resolution, lots of signal. Visually, you get a fully fledged deep-sky telescope with it: globular clusters resolve, nebulae show structure, and planets are tack sharp. These are tubes that serve two hobbies at once.

Why a PDS?

The PDS versions are the photo versions of the Explorer line: the focal point is further out so that a camera comes into focus in prime focus, the tube is internally blackened to prevent stray light, and the focuser is built for the weight of a camera. Visually, you don't lose anything: with the included.

This is how to get the most out of this telescope

• Collimatie is bij f/4,9 een vast ritueel: check for each photoshoot. Our guide to collimation It takes two minutes.
• Include the comma corrector: For sharp stars all the way to the corners of the sensor, this fast optic requires a corrector. Ordering it at the same time saves you a second waiting period.
• Mounting choice: EQ6-R is het absolute minimum; een EQ8-klasse of vaste zuil is comfortabeler.
• Guiding Loon With this focal length, a small guide scope makes the difference between 60 and 300 second exposures.
• Formaat en gewicht: 23 kg buis: een vaste of halfvaste opstelling voorkomt dat het tillen de hobby wordt.
• Give the mirror some cooling time (30 to 60 minutes depending on the size) for the sharpest image, visually and in photos.
• Visual planetary work: a 6 mm eyepiece geeft 250x.

For whom yes and for whom no

Hello de ervaren fotograaf of waarnemer met de montering, de plek en het geduld voor het maximale spiegelformaat.

Not Zonder zware montering en vaste routine blijft dit potentieel onbenut; Wil je deep-sky-foto's zonder montering, guiding en nabewerking, dan zijn de smart telescopes the shorter route; ours Telescope Buying Guide for Beginners explain the trade-off.

Featured accessories

These accessories add the most after purchase:

• Coma corrector At f/5, stars at the edge of the frame appear comet-shaped on the sensor. The Sky-Watcher 2 inch Coma Corrector 1.0x solves this and is the most important first purchase for serious photography with this tube.
• Cheshire eyepiece An imaging Newton only performs with tight collimation; a Cheshire makes the adjustment accurate and fast.
• Light Pollution Filter (2 inch) Under Dutch or Belgian skies, it brings out significantly more contrast in your images and your eyepiece view.
• Moon Filter 13%: with this opening, the moon is blindingly bright; the Omegon Moon Filter 13% (1.25 inches) The light fades. More explanation in our Moon filter guide.
• Carrier bag de 300/1500-tas past deze buis exact. Bekijk de carrier bags.
