    Default First Telescope for deep space objects and nebula etc.



    Hello there everyone,
    I have devloped a keen interest in taking up Astronomy but I have held it off for the past two years.
    I am a porr student so I will be saving for my first telescope. I am really interested in looking at deep space objects, so in terms of practicability, cost and economy of scale. I would think that a dobsonian ould be the best buy. I have been looking at the Meade Lightbridge 8" Deluxe Dobsonian Telescope. Can I humbly ask for personal opinions from people who are familiar with dobsonians ?

    What is the clarity like for deepspace objects ?
    Is it easy to use ?
    hat kind of objects can I expect to see ?
    Is it suitable for beginners ?

    I eagerly await your replies.

    Ah the OLD POOR STUDENT excuse....lol...used it many times long ago simply because I too was poor...so I can relate and I bet quite a few others can relate ...

    But to answer your questions...for DSO's 8 inches gets you off the bench and in the game.. so yes 8 inches is sufficient 10 would naturally be be better but in my opinion not dramatically so...

    Clarity....with a collimated scope...clarity will be no problem IF the seeing conditions cooperate..

    Ease of USE... definitely just point it and look...no electronics no crazy aligning procedures...just plop it down and start using it...

    Objects... lol do not worry about that one an 8" scope can keep you busy night after night until you are an old man...

    Beginners...You bet...cost per inch of aperture is unbeatable, ease of use is also unbeatable ...

    Size/portability can be a problem but normally an 8" dob is considered very portable..

    Good Luck and clear skies...

    Go for it...

    Teashoci,

    I am new to dobsonians and there will be someone with more experience who can give you more tips. But right off the bat, a dobsonian is a good telescope and you get a bigger scope for the money you spend.
    Do you live in a city or out in the country? If you have light pollution issues, then if you are considering the Meade Lightbridge 8 inch, then you will either need to invest in a light shroud to cover the open portion of the scope to prevent ambient light from interfering with what you can see with your scope or you can fashion one on your own.
    Before you make your final choice, look at some other possible options such as the Orion, Zhumell dobsonians, you may even get a good deal on them.
    With respect to clarity for deep space objects, the bigger the telescope, the more its light gathering ability, which can translate into more detail in what you see.
    A dob is pretty easy to use if by ease you mean moving the tube around to different objects in the sky.
    You can see so many things with a scope of that size that you will not run out of stuff to see and yes, it is fine for beginners.
    As Bob said, as long as the mirrors are collimated (aligned), then you should have excellent results.
    Enjoy researching the purchase of your telescope and you will find many useful posts and threads on this Forum.

    Thanks very much for both your inputs, my mind now is pretty much decided. I come from Scotland which is far north europe, so getting somewhere that is pitch black with clear skies is not hard.

    I hoe you could maybe answer a couple of more quesitons on dobsonians for me, I would be very appreciative.

    Is it easy to collimate dobsonians, they look to me like fairly simply put together telescopes ?

    Are there any issues with temperature, Scotland is a fairly cold country with arctic wind so we have freezing winters and very cool summers, would this affect when to view etc ?

    Do you ever to take these telescopes in for any kind of service ?

    What lenses ould you advise for deep sky observation ?

    I think thats pretty much covered it, thats again for you previous replies.

    DOB is an excellent option check other brand before take a decision and consider this...nevertheless how big is your dob or which brand for DSO you need good dark skies and a trained eye and good dark adapted eye to the night vision

    a trained eye you will develop with the observation more you observe more trained will be your eyes and every time you will notice more and more details in the process..

    consider a broadband lightpollution filter if you live in a very light pollution site.

    Dobs do particularly well in cold and humid climates. Especially in humid areas because dew isn't a problem like on other scopes.
