  1. £97.00 from Amazon but notice that at many dealers it has gone up to about £150.00 so very close to the Berlebach at £159.00.

    RVO is £94.00 but doesn’t have any stock but say new stock due in about a month. Wonder if their price will go up?

  2. The Bresser does seem to have better optics and higher build quality but the biggest difference is that it has a great high quality CNC focuser that is miles better than the cheap low end focuser on the Evostar. The focuser alone is enough reason to choose the Bresser.

    Used to have one and was impressed by how good it was for the price. Now replaced by a 125mm APO.

    The 26mm plossl that comes with the Bresser isn’t bad and quite usable. For a long focal length scope a great budget line of eyepieces are the Starguiders. Of course you can spend a lot more on eyepieces but the Starguiders are a great starting point.

    The stock finder is poor like most that come with a scope. A 9x50 RACI finder is a popular chpice.You will need to change the Bresser finder shoe for a Synta / Vixen type one though.

    The stock diagonal isn’t the best and just a plastic one as seems to come with most brands. Just get a 2” dielectric diagonal. There are loads to choose from.

    For long refractors most get a carry bag. Geoptik makes some very nice padded carry bags for telescopes.

  3. The CCs hold collimation nearly as well as a mak unlike an SCT and both my 6” and 8”arrived perfectly collimated. Collimation of the CCs is easy BTW should it ever need doing. Not to be confused with an RC that can be tricky to collimate.

    A CC has a parabolic primary and a hyperbolic secondary and have a long focal length whereas an RC has a hyoerbolic primary and a hyperbolic secondary and a shorter focal length which explains the differences in collimation.

    So if buying a CC you can pretty well forget about collimation.

  4. Had a C8, then a Skymax180 and now settled on a Classical Cassegrain 8”. but may be a bit heavy for an EQ5.

    The 6” Classical Cassegrain is very nice though and a great lunar / planetary scope. Big advantage over a mak or SCT is that it doesn’t have a corrector plate so cools down quickly and doesn’t  suffer from dewing. Also has a proper crayford focuser.

  5. Celestron NexYZ 3-AXIS Universal Smartphone Holder

    In perfect working order.

    SOLD

    For some reason only comes with rubber on one of the jaws and the other is hard plastic but I have fitted rubber to the other jaw so it grips much better. 

    Three-axis adjustment. Centre it over the eyepiece with the X and Y knobs, and then move up or down over the eyepiece until you have the entire field of view in your shot.

    Payment:  PayPal ( buyer pays fees) or Bank Transfer.

  6. A Synta 8-24 zoom for my smartphone setup. Same as the Celestron branded zoom but just cheaper. 🙂

    Wanted a zoom with a t thread on the top to use with my TS smartphone holder. The TS holder is really solid as it’s basically an ali plate with an adaptor at one end to attach to the t thread on the eyepiece. Zero flexing. Dead easy to set up the phone as well. 👍🏻
