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: -1The 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.Answer by: Baader Web Team (Admin) on Sep 23, 2020 12:15:00 PMRated: -1

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: 0I 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.Answer by: Baader Web Team (Admin) on Sep 21, 2020 2:48:00 PMRated: 0

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: 1The 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.Answer by: Baader Web Team (Admin) on Sep 21, 2020 3:11:00 PM
