    Swarovski ATX-115: Star-test and Resolution Measurements

    Tammy has now posted an interferometer test report on his X115. Scroll to post #179 https://www.cloudynights.com/topic/426446-swarovski-atx-95-binoculars/page-8#entry11689866 Unfortunately, his sample also isn't very good. Probably pretty representative of the usual high-ish SA samples. This...

    Swarovski ATX-115: Star-test and Resolution Measurements

    David, I have done both. Admittedly, my prism unit is also cherry picked, but with the prism units there is very little visible difference between best and worst units. Swarovski makes the prisms well, and they rarely show the dreaded prism line. So, as long as there is no prism line visible...

    Swarovski ATX-115: Star-test and Resolution Measurements

    Henry, The 1.7x Extender (in the range it gives) gives much better views than the scope + Zeiss 3x12.

    Swarovski ATX-115: Star-test and Resolution Measurements

    Hi John, I use a Velbon Carmagne 830 tripod and a Sirui VH 10 head. They provided a sturdy enough support unless there is a fair amount of wind. Unlike Henry, I don't have the Zeiss adapter for the 3x12. Instead, there's a bit of bicycle inner tube stretched over the Zeiss mono, giving it a...

    Swarovski ATX-115: Star-test and Resolution Measurements

    Thanks Henry both for your report and for sharing the X95 optical test bench report. Both very interesting. Let's hope Tammy gets an X115 tested and shares the results - and let's hope he lucks into getting a good sample. I have done some artificial star assessments on the X115's this year, but...
