eyepieces and filters clean of dust and fingerprints for best results.
The Orion Jupiter Observation Filter works with any telescope, from a 50mm beginning refractor to a 36" yard scope and beyond! The details you see however will be better with larger telescopes. As important as the size of your telescope are the seeing conditions the night you view Jupiter. Astronomers call the steadiness or viewing quality, “astronomical seeing” or simply “seeing.” Nights of good seeing show lots of detail and very still or steady images; nights of poor seeing show an object that seems to be “boiling” as you look through tur- bulent air.
Let your telescope “equilibrate” or adjust to the nighttime tem- perature for best results – you will be able to see Jupiter if you grab your telescope from your heated den and rush outside; but the details will be better if the telescope can reach the same temperature as the nighttime air. This can take an hour or longer, depending on the size of the telescope and the tem- perature difference.
Also, the collimation of your telescope has to be good if you want the best performance of any filter or eyepiece. Refractor
owners can essentially ignore this requirement, since refrac- tors hardly ever go “out of collimation.” If you have a Newtonian design reflector, see our video on how to check and collimate your telescope:
Unlike deep sky objects, you can observe Jupiter at any time it is above the horizon at night – the full moon won’t disturb your view, unless the moon is very close to Jupiter in the sky (such close approaches between two objects in the night sky are called conjunctions). Jupiter can even be observed during the daytime if it is not too close to the sun; but surface detail will have very low contrast.
The Orion Jupiter Observing Filter can also be used on the moon.
