    Default Price performance ratio for Baader vs Celestron Zoom EP can you put a $ difference



    Here is the conundrum I know I want a zoom EP and there are many many reviews that indicate that the Baader zoom is a premium unit. However there are also many good reviews on the Celestron zoom and the price is 1/4 of the Baader unit.

    So the question is what are the technical reasons to justify the difference in price. The question is not about the budget but what are the factors that improve the performance and can dollars be associated with these differences.

    Is the cost to get the wider FOV driving the cost, is it the coatings, lens design or ????? I am willing to pay more but not more because of where its made but only if I can justify the performance is there. I have searched many forms, google and so on which has me close to pulling the trigger but I am hesitant that there is more hype than actual performance that can be noticed while using them.

    Thanks in advance for your help and advice.

    Don

    Better quality control (expensive), better coatings, possibly better grade of glass, better fit and finish.
    The Celestron has been around for years in its current form, the Baader has been continuously upgraded hence the Mark IV designation.

    Hello Don,

    according to the reports, the Baader Mark III and IV is optically heads on with the top premium Zeiss Diascope Zoom.
    The machanics of the older Baader Zooms has been reported to fail at the low ambient temperatures, the IV version has been improved (?).

    The long story short:
    Besides several exceptions, all zooms are in sharpness, contrast and transmissivity behind the premium fix focus eyepieces.
    And here are 2 exceptions:
    The Tele Vue Nagler 3mm - 6mm Zoom performes better than all fix focus (7 lenses in 4 groups) eyepieces from China and Taiwan, but it is behind the Abbe orthoscopic and Steinheil monocentric eyepieces. I take it for the fine tuning to the seeing conditions on the planets, before switching to the Abbe orthos.
    The Leica Aspheric ultrawide (up to 80° AFOV) 9mm - 18mm Zoom is nearly heads on with all my fix focus Leica, Swarovski, and Zeiss eyepieces, beating the Pentax XW 10mm by a small margin.

    Hoping this helps,

    JG

    Like most things we acquire as the quality improves the price skyrockets. Each small step up comes at an ever increasing step in cost. I have both and yes the Baader is better. In my nice spotting scope the difference is quite small but in my C8 the Baader is clearly better.

    Your views are never better than your weakest link in your optical chain.
    Unfortunately prices for astronomy equipment do not go up on a liner scale. Those first few steps are relatively inexpensive for a large jump in performance. But then it's huge jumps in prices to get that last 10-20% of performance. The Celestron zoom is decent, the Baader zoom is better.
    I still have my Baader zoom, but in most cases I prefer fixed length eyepieces over the zoom.

    If you think it's all "Hype", then go on Ebay and get one of those ultra cheap zoom's. This one has great reviews and it's only $8.95 with free shipping.

    Hello all,

    this sort of straight view zooms used to be made in Japan and mounted into the small spotting scopes
    https://www.ebay.com/itm/Vintage-Tas...-/273087534364

    The view has been like through a drinking straw, one of them has passed my hands, but in a swift way,

    Well I pulled the trigger today and ordered a Baader and some other bits. I will give an update when I get to use it.
