    Default FOV for Baader Hyperion Zoom?



    Hi Folks,

    I just purchased a Mark III Baader Hyperion Zoom (my Xmas gift to me!) & was looking for information about FOV.

    Only info I can locate is that at 24mm the AFOV is 50* & at 8mm its 68*. I keep an EP chart that shows the AFOV & TFOV and wanted to fill in the blanks

    Any idea what the FOV be at the 12, 16, & 20mm settings?

    Thanks

    Interesting thread. The zoom is a great all around tool. The FOV's are nice IMO until you reach the 24mm. It's FOV is definitely plossl like. It ain't no TV or Pan but it gets the job done.

    For some reason I was not able to reach focus with it when I tried it out tonight. I can't focus inward enough. I am going to see if I can return it.

    That was an interesting thread - most of what I read about the Hyperion Zoom in the past was good, this thread made me think twice. I wanted to use it to find objects & then get closer & then switch to a fixed lens. But with <50* AFOV at 24mm it may make objects more difficult to locate.

    Yep, it may not be eyeful enough Alan!
