    Default Orion 4.5" opinions



    Looking for a beginner 'scope for my family. Would the Orion 4.5" dob be a
    reasonable choice?
    Thanks for your opinions.

    I got one for my 7 year old son for this Christmas. It is an excellent
    scope. Comes with two good eyepieces, light enough for my son to carry
    (I think) and low enough to the ground for children to use without hassle.

    I think it would be a reasonable choice, nice and compact, enough aperture to
    show some nice deep sky objects and reasonable detail of the moon and planets.

    Currently this scope is on sale for $159 plus shipping so that makes it even
    more attractive.

    A similar alternative would be the Hardin Optical 6 inch DOB which is on sale
    at a variety of vendors (DBA astronomy Products is one) for $199 plus shipping.
    The larger mirror captures a good deal more light than the XT4.5 which is
    quite an advantage. The scope is larger which may or may not be a problem.

    But the bottom line is that yes, the XT-4.5 is a good scope at a reasonable
    price. The simple DOB mount is easy to use and solid and stable, unlike the
    shaky EQ mounts that come with Department store scopes. The finder is a good
    one as are the eyepieces.

    This is a good quality instrument put together with the idea of producing a
    competent package at a great price. Orion is known for its customer service
    and part of that service is providing well thought out scopes like the XT4.5.

    The XT4.5 Dob is a good size for kids, but adults
    will find themselves on hands and knees for hunting
    and observing.
    The 4.5" StarBlast is an equivalent table-top choice.
    Even lighter and more compact. Also comes with an
    EZ finder, which many prefer.

    I think it is important to point out that the Star Blast is an F4 scope rather
    than the F8 of the XT-4.5.

    F4 will be much more difficult to collimate and will have much more coma. The
    steep angle of the an F4 light cone will also cause serious aberrations in most
    eyepieces..

    Thanks Jon. I almost went back to mention that.
    'Comparable' may have been a better word.

    Hi Jon:

    And yet...and yet...

    The StarBlast does a remarkably good job, even on the Moon and planets, wiping
    the floor with my poor 80 f/5. And it features that spectacularly wide field.

    Peace,

    More personal preference.
    How much coma/abberation will one tolerate for a
    substantial gain in field?
    Kinda like 'how much clarity will one sacrifice for extra
    magnification?'
