    the arm inside of the telescope is of very bad quality, I have a lot of problems of “No Respond 16” . I have opned the arm, and the circuits and connectors are of very bad quality.

    Hi! I am looking to buy a telescope for my husband for Christmas. He is a beginner but he has a passion for the sky and I want a telescope that will go a long way. He reads a lot and is a good problem solver. I don’t have a huge budget, was looking at the Celestron Nexstar 4 or a used 6 SE but after reading your review, I thought that maybe I should head for the SkyScout as you suggested. What telescope would you recommend to go with it? Any help would be appreciated as I don’t know anything about telescopes. Please answer through e-mail if possible. Tx. Sonia.

    • The SkyScout is not a telescope, it is just an aid for finding objects in the sky and getting information about them. I recommended this because I had such a hard time getting the telescope’s built-in computer to work. So I would probably recommend getting a nice manual telescope without a computer (they are less expensive), and then getting the SkyScout (or something else) to help find and identify the objects.

      There are other aids you can use instead of the SkyScout. For example on my Android phone there is a free app called Google Skymap. You just hold it up to the sky and it shows you what stars you are looking at, and their names. This is great for finding stars and other objects and it is free, which leaves more money for a better telescope.

    Thank you very much for your answer. I know it’s a tricky question but If you had to recommend a good manual telescope to a friend, which one would you pick? (I can be flexible with price but I am aiming at the $500.00 to $700.00 range). Also, how easy is it to find the objects in the sky with the telescope after identifying them with the Sky Scout? Thanks. Sonia

    • I wish I had enough experience with telescopes to give you a recommendation. I would recommend reading this beginners guide to telescopes. It is very good and helps you identify what kind of telescope to get. Read the part called “So, which one should I buy?” and also look at the pros, and cons of each type of telescope.

      As far as the Sky Scout goes, since it does not attach to the telescope it won’t directly help the telescope find the object. However, each telescope should have its own finder (a smaller scope attached to the side). Using the finder, it should not be hard to get a rough location on the object (just keep an eye on it after using the Sky Scout), then you use the telescope to do the fine adjustments.

    Reading your review I feel that you have one of a batch of scopes that was recently produced (since July 2010 the we are aware) which had a manufacturing defect – in that the arm was not orthogonal to the base. This would mean that both alignment and tracking were poor.

    Celestron are aware of the problem and have rectified a number of scopes under warranty.

    The scope (and NexStar mount) are generally excellent so I would investigate the mount (if you still have the telescope). If not, I would request a second example and check that the arm and mount base are orthogonal before carrying out a second review.

    There is a discussion of the problem on the following forum:
    http://tinyurl.com/3abux8v (and there are also severel follow-up threads).

    Hope this helps

    • If you look at the date of this review you will notice that it was done back in 2007. Also I admit that I am not very knowledgeable about astronomy and that may have been part of the problem I had. The alignment process was just so complicated that a beginner like me would just get frustrated. That is why I recommended the Skyscout. It does not require any alignment, it just works. Why can’t the telescope be the same?

      I sent the telescope back to Celestron when the review was done, but if you would like to send me another telescope I would be happy to review it and see if things have improved.

    Is it true that the Nexstar 4SE has bad quality tracking and alignment as said by Dunc late last year?

    Hello, I want to comment on something with regard to this telescope.

    All the telescopes desalinean to the minor movement. It is logical that on having moved the mount desalinee. because of it the unit of control is remote, not to touch the telescope and only to look for the ocular one.

    The principal virtue of the SE4 is his low weight and size, which it does a portable appliance of presentations similar to telescopes of major size.

    With regard to the cable 232, all the telescopes so many celestron since meade include 232, not USB. is a norm commonly and is not an own fault of the SE 4.

    A greeting from Argentine.

    Forgive the English evil. A translator uses

    I have a new nextar SE 4 but I can see no light through it. I have tried to flipp the mirror to the upper position and also to see objects during the day. Improvising a little, a tried to use the objective at the back part, where the camera supose to be attached, and I could see light. Can anyone help me? Do I need a diagonal?

      Probably should turn the sense of the mirror. It has two positions. To see for the ocular one it is necessary to leave it in a position, and to see for the hole for the chamber it is necessary to put it in another position. Do not forget to remove the lid of the primary lens and to place an ocular in the hole for ocular!

    Try skysafari 3 with skyfi. It’s a wireless connection with an iPhone . The skysafari program comes in 3 versions : basic , plus , and professional. Only the professional and plus versions have the ability to remote control the scope the basic version does not.
    I’ve been testing my 4se setup with skysafari 3 plus version, skyfi , iPhone yesterday, and I really don’t see and problems yet. I’m planning to purchase a 9mm or 20mm illuminated reticle to more precisely align the three stars.
    The software and hardware is from Southern Skies , Orion telescopes have
