    again,personally i would go for the 1200 f/l.
    others may advise on the 750f/l,which is a
    faster scope.a faster scope tends to need better
    quality ep's than a slower one.
    but tbh,i wouldn't worry about this until you have
    more experience and your eyes are trained.
    use the kit that comes with the scope for a while,then
    think about other ep's etc.

    I agree with the calculations, but I still submit that the vast majority of observers will be hard pressed to see any significant difference (if they can see any at all) at the EP between a 130mm (5.12 in) and a 150mm (5.9 in). But irregardless of that, I will always encourage anyone to buy as much aperture as they can afford, as long as the mount can handle the load. Agree with Rich about the dobs, best bang for the buck you can find.

    5.1" or 6"
    take a look here,pretty much the same thing.
    i covered the differences with the mounts there,
    and f/l with the 150p/150pl.

    OK, just to be a bit more intrusive? Because of the mount, given the choice of those two telescopes I would definitely go with the 150P.

    Now to try to steal some of roverich's thunder. . .

    Since both of the two telescopes you're looking at will be good only for visual purposes I'd get the Skyliner 150P before I'd get either of the other two.

    With the Skyliner you'd have a more stable mount. You'd pay less than for the Explorer 150P. You'd also have more friendly optics.

    The Skyliner is f/8. As an f/8 telescope it is likely that you would be happy with the included eyepieces. With either of the Explorers you'd be getting f/5 optics and there is a pretty good chance you would not be happy with the included eyepieces. The eyepieces you may end up thinking you need to buy could easily exceed the cost of the telescope itself.

    Your viewing is likely to be more comfortable with the Dobsonian as well. Equatorial mounts paired with a Newtonian reflector can at times make for rather unpleasant viewing.

    IMHO, the Skyliner Dobsonian would be a better value.

    FWIW

    Thanks for the info, its more than welcome, but i think im getting either a Explorer 150P or the 150PL. Due to all replys including yours.

    Very glad I found this forum

    night porter,

    As someone mentioned earlier, a 150 mm telescope is the dividing line where you start seeing details of deep space objects. This is your first telescope and you really don't know where you will end up in astronomy. Getting a telescope that is flexible and lets you explore the many aspects of amateur astronomy makes a lot of sense. Unlike many of the telescopes discussed in this thread, the Explorer 150P or 150PL will do just that.

    Either of the two telescopes you are now considering, the Explorer 150P or 150PL are excellent first telescopes. The differences between the two telescopes are small. With the 150PL, you will see more details of both Saturn, Jupiter, and, every couple of years when Mars is close, Mars. Both will be very good for deep space objects with the 150P having a slightly larger field of view which is useful for a few objects. However, the 150PL will be no slouch either. The focal ratios of these two telescopes are not that far removed which means that eyepiece selection can essentially eliminate the differences except at the extremes of each scope's performance range.

    I'd personally go with the 150PL for the following reasons:
    1. slightly better planetary views
    2. less finicky about eyepiece quality
    3. a solid performer for deep space objects
    4. longer back focus which is useful should you ever want to do some photography
    5. built-in DSLR camera connection
    6. better eye relief at higher magnifications (this really is not a factor for deep space objects but is for viewing planets or the moon at high magnification)

    One aspect about the Explorer 150 P or 150PL not yet discussed is its EQ3-2 mount which is well suited for either the 150P or 150PL. The EQ3-2 mount can be upgraded. You can add dual drive motors to it or even add a goto capabilitiy should you ever want either of these capabilities. This you can not do with the Explorer 130P or the Dobson telescopes discussed earlier in your thread.

    Either the Explorer 150P or 150PL is definitely worth the extra money over the Explorer 130P. True the difference in viewing is not that much but it is there along with the capability to resolve finer details, separate double stars, see fainter objects. A 150 mm telescope is as large a telescope as many people ever use and many advanced astronomers use smaller scopes. The Explorer 150P or 150PL will let you explore all the major facets of astronomy. With the addition of a drive on the EQ3-2 mount, you can even explore photography.
