    Default Can I see any spiral galaxies with an etx-60at ?

    Hello all, I am a Newby to this group and astronomy.
    I have an etx-60at with the 25 and 9mm ep's. Im in Montana near the western
    border of Glacier National Park where the skies are pretty dark when theres
    no moon.I have a pretty good view of the southern skies from home but a good
    portion of the north and west are tree covered with about 40 to 50 ft trees.
    I guess the planets are pretty neat to look at but really want to seesome of
    those galaxies Ive seen in the pictures.
    I have easily found orion, the moon, saturn and mars. With this scope would
    I be able to see or distinguish any spiral galaxies ? I cant seem to see
    from my place but have heard its pretty big. What skies are best to view
    with theis little scope ? I know where I can get a etx-90c if and am
    thinking of getting it unless it would be better to wait and get somthing
    Regards ant thanks for any info. Jim

    Hello: Andromeda should be easy to see in your etx-60. But do not
    excpect to much. For deep sky objects you would be much better off with
    lets say a 6" dobsonian.

    However, upgrading to a ETX-90 will be a good idea. Not only will you
    get some more power you will also have a very good planetary scope
    which will hold water to any 3" apochromat in this respect (forget all
    the refractor junkies without any clues who wants to trick you into
    their weired world view) . Resolving double stars will also enjoy you.

    Btw. I have never used it, but there exists a wide field adapter for
    ETX type of scopes. A ETX-90 will only have a focal ratio of f/14. The
    latter means observing rich fields makes it hard. The wide field
    converter will turn any ETX-90 to an f/7 scope. The adapter costs
    around $100.

    When you apply for an ETX-90 do not forget to get one with UHTC
    coaings. The coatings are a bit better than standard Meade coatings.
    Which means the ffective ligh throughput is a bit increased. Maybe you
    know that mirrors loss light when reflecting that means your ETX-90 is
    by no means an effective 90mm telescope performer when you speak of
    light throughput. The effective light throghput will equal a good
    unobstructed 7.5cm or 8cm apo so to speak.

    If your budget says yes, you could also get a Meade ETX 105 UHTC. I
    onced used such a beast and it had outstanding optics and kicked ass my
    Borg 76mm ED apo any time. Btw: the Borg ED apo was no better on
    planets than my 8 year old ETX-90 that was the reason why I sold the
    Borg ED 76mm since I was a bit disappointed.

    Btw: If you want to educate yourself a little bit stop by the
    following site:

    [Especially the section about "High Resolution"].

    I gather from your post you are an avid beginner. My only tip for your
    forthcomming life: beware the refractor junkies they are out of sync
    with reality.

    Otherwise enjoy your hobby it is great and intellectually very

    In another thread, I stated that I would keep my 127mm Achromat. But the
    parameters on that choice were dependent on what is currently "in the barn".
    Based on my positive experiences with that scope, I'm buying a 6" F5
    Newtonian to mount it on my Unistar Deluxe (yet another trial scope).

    Ask me again in a few weeks which scope I'd keep.

    IME, what scope is the best, has little to do with the design, and more to
    do with aperture, quality of view, and budget. I'd say beware the big scope
    junkies who've lost the desire for small scope views.

    Purchase a scope that is the best trade off between aperture and mount. This
    is why the Dob is so popular. The mount cost next to nothing, which means
    more can be spent on aperture.

    But this is only good to a point. What that point is, depends on the
    individual. Your (un)willingness to setup a scope larger than 8" aperture
    might surprise you, especially if you more observing skill and experience,
    than you do time and opportunity.

    Given dark skies, a tight budget, and the ability to own just one scope, I'd
    shoot for something in the 6" (150mm) to 8" (200mm) aperture range. Big
    scope views are sweet, but you might find that a scope that you use all the
    time, is better than one that has a high "wow" factor. I'm sure some folks
    would rather take out the "wow" scope once a month, than take out something
    small three times a week. Nothing wrong with that.

    I am oftentimes very patronizing because when I was young I had bad
    teachers in astronomy. I wish back the times when I was younger but
    under the assumption of having a Newtonian 130mm and not my Vixen 10cm
    f/10 achromat. In Germany at this time there happend pure refractor

    However, observing Mars with my Vixen achromat was a nightmare; can be
    said too for observing Venus in daylight.

    Years thereafter I have witnessed what it means how Mars should look
    like: it was when I bought me a Maksutov 15cm. Wow what a pleasure.

    But this is long time ago. In the meantime I completed a Master degree
    in astrophysics. Heck my Master thesis dealt with building a solar
    telescope for observing and scrutinzing the solar photosphere by means
    of a CCD camera.

    After that I completed my Phd in physics.

    But I feel still deprived of my youth. I begged my mother for getting
    this 10cm Vixen f/10 achromat where at the same time the shop had also
    this Vixen 130mm Newtonian.

    PS: My scopes thus far: ETX 90, ETx 105 UHTC, 15cm Maksutov, 10cm Vixen
    achromat, 76mm ED Borg apo, ocassionally a 35cm Dob, 5" Meade ED

    That is the reason why my ETX 90 is used most often since I do not own
    a car and hauling around telescopes is not that easy in this respect
    especialliy if you a living in small town with lot of light pollution
    and backyards some kilometers away.

    But the ETX 90 can be transported.

    That's not possible! You can see M31 with binocs! You can even see it as a
    smudge with the
    unaided eye. my guess is you can't locate it.

    You should be able to find many many galaxies, some of which will
    be spiral galaxies. However, the will not look like pictures,
    because the human eye doesn't have the persistence of image like
    film or electronic imaging.

    I would highly recommend that you purchase a copy of

    Lugunbuhl and Skiff, "Observing Handbook and Catalogue of Deep-Sky
    Objects", Cambridge University Press (1998).

    Perhaps you have located it, and are seeing it, but have a preconceived notion of what
    you expect to see.
    It's not going to look like the images you see published. It's going to more resemble
    a smudge, or a glow around a bright star.

    Hi !

    I'm sure you're going to get a lot of useful advice here. My two cents is to
    keep in mind that for most spiral galaxies, the arms are a lot fainter than the
    core of the galaxy, so if you see anything at all you'll see the core as a fuzzy
    star-like object long before you'll see the spiral arms. And no spiral galaxy,
    nor anything else past the solar system is going to look like the photographs,
    as they're the result of exposing the film for dozens of minutes, or a CCD
    camera for minutes, to capture enough light to see those very faint details.
    That said some structure is visible in amateur telescopes, if the skies are dark
    enough and the telescope is large enough. M104 the Sombrero looks distinctly
    non-star like, although a very large telescope is required to see the dust lane.
    NGC 253 does not look starlike either.

    Good Luck !
