Customer Q&A

1 - 5 of 12
1 2
  • Q1: I live in the Philippines, does the Go-to accept long.-lat. for my location like the ones on Meade telescopes or does it only have city inputs?

    A: The GoTo system that this telescope runs on is universal and will work with your location.

  • Q2: I'm interested in viewing (in good detail) the ISS but do not see any information on each scope saying it can be used in this way.

    A: The ISS moves too fast to stay in focus using a telescope. The only way to view the ISS with detail would be to use some astronomical hand held binoculars.

  • Q3: I'm planning on getting this scope, could you give me a summary of what it can see object wise?

    A: You should be able to see lunar features less than 2 miles across; dark surface features on Mars, detail in Jupiter's cloud belts and the cloud belts on Saturn, faint stars down to about magnitude 13, plus hundreds of star clusters, nebulae and galaxies, with hints of spiral structure in some galaxies. You'll also be able to see all the Messier objects, plus many NGC and IC objects under dark skies.

  • Q4: Is this scope good for terrestrial viewing?

    A: The Celestron NexStar 4 SE is good for land and sky viewing.

  • Q5: Is your free shipping offer valid for shipping to Canada?

    A: Unfortunately, free shipping is available only within the continental U.S.

  • Q6: Will I be able to move the scope manually if the batteries die, or will this cause damage to the motor?

    A: The Celestron NexStar 4 SE Telescope must have batteries to operate. Moving the scope manually will harm the motor.

  • Q7: Will I be able to see details on planets like Pluto/Neptune using this telescope?

    A: No the NexStar 4SE is not capable of viewing Pluto or Neptune. You need a telescope at least 6" in diameter to view Neptune. Pluto is always unviewable because it is so small and dark that even the Hubble cannot clearly view it.

  • Q8: Will I be able to see nebula and galaxies with this telescope?

    A: The Celestron NexStar 4 SE Telescope is very capable of seeing planets, star clusters, galaxies as well as nebulae.
