    Has anyone tried using a quality 2" Barlow for DSO imaging? It might be nice to reach out to Targets such as M1 or M57, without having to change out the Scope. Just asking??? AlanP

    Hi, I just received the Televue 2" 4x, it works well with the Orion 80 ED triplet telescope, I used it with the 2" Baader diagonal and a 20 mm Celestron Plossl eyepiece, just looked at the moon and Jupiter and the image was fantastic, clear and without any aberration. In a few days I will receive the T Adaptor and may be i'll take some photos. Bye!

    I wound up buying the Zhumell 2x ED 2" which I believe is just a rebranded GSO. It is a solid accessory. Now I just need to get better eyepieces. Hoping to get a few ES 82 degrees.

    Try to get some Nagler or Radian, they are not cheap but both have a tremendous quality for seeing or take photos, what you pay is what you get. Regards.

    Of course, for planetary observation barlows help a lot! The best quality they have the best results you are going to obtain!

    Thank you all, I just ordered the Seben 2x Barlow BA1 that WWPierre recommended. I will try to observe Jupiter using it, hope this time I will be able to see details such as colors and the "bands". Using just the original parts that came with the XT8, I just can see a relatively small bright circle; let me know if it is normal. I think I collimated it correctly.
    Thanks

    Using the 25 mm Sirius Plossl that comes with your xt8 you obtain just 48x (1200 mm divided 25 mm) at that magnification is normal to see Jupiter just as a bright little circle. At 96x, that is 48x provided by your eye piece multiplied the 2x provided by your barlow you just begin to see the bands of Jupiter. I recomend you to use some 12 mm focal length or less eyepiece with the 2x barlow applied. Happy New Year!!

    Carlos.
