Askar 71F Flat Field Quadruplet APO Refractor - Full Review

Ғылым және технология

This is my full review of the new 71F quadruplet apochromatic refractor telescope from Askar. It's an excellent little telescope both for visual observations as well as for astrophotography. Check this video out to find out more about its strengths and weaknesses. Enjoy!

    I own it. I love it. The only thing I had to do was get some riser blocks so I get my auto focuser to clear the dovetail plate.

    Askar makes some decent scopes for the price point

    To be honest considering the aperture, these pictures are pretty amazing, good scope for photography in my opinion.

    Picked it up a couple of days ago. My initial concern and probably the only concern was that it was bit slow at f6.9. But as someone who lives in Arizona with 320+ days of clear weather, I don’t mind the slow scope at this price. Ironically haven’t got a chance to test it yet, because it’s been cloudy since the day I got the scope 😂

    It appears to be an extraordinary well built telescope. However, that is a really small aperture limiting light collection.

    The 51 Redcat is even smaller and it does a good job of collecting light/imaging.

    Any telescopes primary purpose is to gather as much light as possible. All things equal, go bigger. (Ed Ting) To each their own. Thanks! -mike

    Thanks Bogdan, I've a Skymax 150 and im looking for something that's better for deep sky objects, in your opinion do you think this would be better for this?

    @graemedevine9651 Yes, because the FOV of the 71F is much wider than the one of the SkyMax and will allow for wider DSOs to fit in one frame.

    @@graemedevine9651 Прошу Вас, прежде, чем делать такие заключения почитать теорию астрофотографии и технические характеристики телескопов, а именно конструкцию, что такое ED, APO, Super APO, Triplet, Quadruplet, в чем между ними различие и как это различие влияет на качество картинки Если не вдаваться подробности, то условно существуют телескопы для визуальных наблюдений и для астрофотографии. В астрофотографии крайне важна максимальная коррекция оптических аберраций различного порядка, от простого хроматизма, до сферических разного порядка. При визуальных наблюдениях, в первую очередь важна апертура, а при астрофотографии светосила. Да, это прямо связано между собой, но это связано большой разницей в стоимости телескопов. Телескоп из видео чисто для астрофотографии, визуально в него только если на Луну смотреть. Ваш Skymax 150, это телескоп чисто для визуальных наблюдений. Explore Scientific 102mm F/7 ed APO отлично подойдет для визуальных наблюдений, для фотографии объектов дальнего космоса, вам надо дополнить его редуктором фокуса и корректором поля.
