    Default Final advise before 1st (real) Telescope purchased next week



    Hi All!

    I currently have a Celestron TravelScope 70 and am very happy with it. I have been looking for a 'proper' scope for the last 6 weeks or so and have a budget of £300 max. In fact, my other half is getting it for me for my birthday on 1st Sept, so there is no leeway in that!

    I think I will be doing spontaneous planetary viewing and some of the main Messier's. Maybe some some very amateur Astrophotography thrown in - more to show others what I have seen than to win awards! No more than a few seconds exposure and I know a MD can be added to most scopes.

    So here is the dilemma. I thought I had it sorted with a Skywatcher 150p on an EQ3-2 mount. (£296). I thought i could add the GOTO/MD later and that was the scope for me. The last few days I have been wondering if the Skywatcher 130p SkyScan GOTO would be better (£299). Smaller reflector I know, but it is a GOTO.

    SO do you all think I am better off getting the larger scope and adding to it or the smaller (and more portable as it will probably get put away most evenings) GOTO scope. Is there a lot of difference between 150mm and 130mm? (except for 20mm!)

    Your views are welcome - I am spending (her) cash next week!

    Thanks - you all are a brilliant help to me re-kindling my hobby!

    Clear Skies!!

    in my thoughts i would go with the goto. since UK is limited in clear skies. you could spend more time looking at things or more time looking for them.
    My wife said she will leave me if I buy anymore astronomy gear..... Boy will I miss her !!!

    Either will give nice views with the 150P being somewhat brighter. Depending on your LP the GoTo could make viewing "easier". If you can find thing with your 70 without GoTo it might not be as necessary as for a true beginner.
    Good Luck

    Of the two, I think you should go with the 6". In amateur astronomy, aperture is king, and the convenience of the go-to may not outweigh the loss of brightness and clarity dropping from a 6" to a 5" mirror.

    Think of it like this, a 6" mirror gives 6x6 = 36 square inches of light-gathering surface (ignore the fact that the mirror is round :-)). The 5" gives 5x5=25. Therefore, the 6" gives almost half as much again in light gathering surface as the 5".

    There is one other consideration. You are thinking about buying a reflector. but have you considered a Maksutov?
    The focal length of the 5" go-to reflector is 650mm. So, for instance, a 10mm eyepiece will give you am magnification of 65. The focal length of the Explorer 150P is 750, so that eyepiece will give you a magnification of 75.
    The Skywatcher Skymax 127 Maksutov, although a 5", has a focal length of 1500mm, so your 10mm eyepiece will give 150X. And it comes on a very accurate go-to mount. Admittedly, it does cost a bit more (£379 from First Light Optics), but I think you should maybe consider it as a best of both worlds alternative.
