    9/23/2020 11:08 AM Baader UBVRI Photometric Johnson/Bessel V-Filter (4mm Glass)
    What is clearance required for insertion into a filter drawer - eg the altair astro filter drawer

    Answer rated: 0
    The 1.25" filters come in a Low-Profile filter cell, which is 6mm high (plus the filter thread).

    The filters glass is 4mm thick.

    9/23/2020 9:32 AM Baader MaxBright® II Binoviewer with case
    I am considering a purchase of binoviewer to use with my 305/1500 collapsible SkyWatcher dob. I would like to use ADC for planetary viewing, hence I need at minimum a 2x barlow/f.extender. my question is: could the 2.6 GPC be placed before ADC, i.e. can additional 55mm of lightpath be introduced between the GPC and binoviewer (OTA -> 2.6 GPC -> ADC -> bino)? Focusing distance is not much of an issue, since mirror can easily be moved. I am more interested in understanding how GPC will behave - is it sort of telecentric or 2.6x effect with distance becomes 3x or more.

    Answer rated: -1
    The glasspath corrector behaves more like a barlow lens than like a telecentric - it's best if you think of it as a barlow lens which also corrects the colour aberations of the prisms.

    9/21/2020 8:11 AM Baader UV/IR Cut / L-Filter
    Why do you say the filter is only good for 100mm+? I have a 97mm Brandon apochromat. Will it work with it?

    Answer rated: 0
    I can't find where we state that it is only for larger apertures, but there will be no problem using it with smaller telescopes, as long as chosse a matching size.

    9/19/2020 11:18 AM Baader Micro Guide eyepiece with Log-Pot illuminator
    What is the width of the field stop diameter?
    What is the width of the apparent field of view?
    Thank you for the answers.

    Answer rated: 1
    The field of view is 45°.
    We do not have the diameter of the field stop available at the moment, but it is an orthoscopic eyepiece, if this helps.
