    The tal one has a sturdy mount and good optics, the main mirror is 110mm Dia.

    Changing the telescope for one where the mirror  is only 20mm bigger and has a flimsy mount is not worth it.

    save up a bit more cash and look for a good second hand dob in the 200 to 250 mm range.

    Don't buy a second hand scope off the internet with out looking at it, and take some one with a bit of experience with you when you view it.

    Always inspect the coating on  Newtonian mirrors they can tarnish and  cost over £80 to re-aluminise,  sometimes the surface of the mirror can become etched making it useless .

    I hope i have not put you off getting a bigger scope, there is a lot of good secondhand stuff about.


    Thanks Jim, I appreciate the advice. 

  2. Thanks everyone for the replies. Its much appreiciated.


    Ronin, that certainly is an interesting point, I would want to be able to see more after upgrading.


    I will look second hand, but being in Ireland the local market is small, not many folks willing to ship over from the Uk, but i will look anyway.


    Again, thank you all for the advice.

  3. Folks


    I was looking at getting a new scope to replace my old TAL-1.

    I have seen these three but dont know which would be best, or even another. Budget less than £200







    Any advice would be gratefully received.





  4. Thanks for all this advice guys.

    Just out of interest, have you collimated your scope recently? You'll have a much better chance of seeing something if it is.


    Tony, I bought the scope second hand in the summer, the guy I bought it off handed used it in quite a while so I presume it hadn't been done for some time. As a newbie I didn't know how, and was happy with the image I was getting, mostly the moon, when I took it out. Mars was the first object that I really looked for hence the question.

    Yesterday I looked at the manual regarding collmination and yes it is off a far bit. Also the primary mirror is very dusty, as is the optical tube and the diagonal mirror has a fingerprint on it.

    So bravely (or naively) I have removed them, cleaned out the tube, and washed both mirrors. Not a very hard job when I followed a post on here to be honest.

    Then tried collminating the diagonal mirror and now one of the adjusting screws for it snapped its head, so I have a post in the Wanted section to see if anybody knows where I can buy one, or packet, of these.

    Hopefully this is possible, must check the bay now, and the images will be much better....

    .. couldn't really be any worse.

    But to everyone that gave me some advice on this, again thank you you have give me some encouragement.

  5. I am somewhat of a novice, havent been able to get my scope out much since I bought it.

    I was out las tnight wit hmy Tal-1 and tried to view Mars. Lined up, 25mm eyepiece, zoomed in to the 10mm, then then added the barlow x3.

    Thing is my view of mars was like a cream dot about 2mm across the eyepiece.

    I know that the scope is relatively small, and for look at the moon it can give great detail, looking at Plaides (spelling?) afterwards was incredible, all the others stars around it, breathtaking!,

    but Mars disappointed!

    Is this what I should expect from my Tal or is there something I am doing wrong with it? :D

    Thanks for letting me rant

  6. Enniskillen eh, Im from Ederney myself, if you remember it....

    YMCA aint there now more, prepare yourself for a shock...........

    The tech was flattened about three years ago and new ultra modern one built on the lot, the townhall in the middle of the town, the same and art centre and exhibition hall, the Mart showgrounds (Sedan Av.) now a shopping centre, the Royal Arms hotel, floored and now a shopping promonade.... and finally Sally OBriens at the head of John Street brought to the ground just this week ;):wink:

    There are probably a lot more changes (especially the bottom of the town :(), but I cant think just now but definately a different landscape now than then, but hi thats progress for ya.
