Instructions for use
107PHQ 作为Askar 第一款长焦比、自平场摄星镜,有着它特殊的使
命。不管是刚入门的小白还是资深爱好者,都能轻松简单的使用它。
入门爱好者再也不必出于拍摄目的去购买必须附加的平场镜,也不需
要计算平场镜的后截距以及繁琐的连接达到匹配的距离,直接接上任
意成像附件,合焦后就是最佳的拍摄状态,轻松搞定,让您有更多时
间投入到其他拍摄工作中。
ASKAR 107PHQ 是一个真正的全能型选手。
一台几乎适用于所有用途的望远镜,而这也正是107PHQ制造的目的。
107PHQ采用f/7焦比,四片式光学镜片组合,其中两片为ED玻璃。因
此,107PHQ有着非常好的色差控制能力,即使目视放大到300倍也能
有效纠正色差问题。
由于采用自平场设计,107PHQ在天文拍摄中具有很强的优势。它不仅
支持全画幅44mm影像圈,而且周边星点变形极小。视场中央星点
RMS半径只有3微米左右,星点细腻,可以满足严苛的资深玩家对星点
的要求。 像场整体非常平坦,周边减光也非常优秀。
凭借749毫米的焦距和强大的像场修正,搭配高分辨率相机进行天文拍
摄时,天体的精细细节也可以被轻松捕捉到。
用107PHQ进行目视观测也是非常理想的选择,无论是连接1.25英寸,
2英寸天顶镜还是各种目镜,都能轻松合焦,甚至超高倍观测行星也不
在话下。

As the first long-focal-ratio Flatfield astrograph from Askar,
107PHQ is born with a special mission: whether you are just
getting started in astrophotography, or an enthusiast who
has been quite familiar with all equipment and devices, you
can always find Askar 107PHQ a useful astrograph which is
functionally practical and physically attractive. It’s especially
amateur or beginner friendly since you don’t need to attach
an extra field flattener to get a satisfactory picture. And for
the fact that you don’t need a flattener and you can easily
get over back-focus calculation and confusing connection
steps, all you need to do is to equip your 107PHQ with any
possible imaging devices, make the target stay at the focus,
and then the whole optical system is perfect for imaging.
Askar 107PHQ, a versatile all-rounder.
Askar 107PHQ can literally be applied in any conceivable
situations, and that’s the top reason why 107PHQ is
produced: to slash as much trouble for users as possible.
Askar 107PHQ, an f/7 astrograph, contains four pieces of
lenses including two pieces of ED glass, which can better
reduce chromatic aberration. It can achieve excellent color
correction even with the magnification mounting to 300× in
visual observation.

The built-in Flatfield lens is a great contribution to Askar
107PHQ’s imaging ability. It supports 44mm full-frame imag-
ing. The stars around the corner of the images seldom suffer
from distortion or deformation. At the center of its field of
view, the RMS radius is merely 3um. Even a fastidious user
can also be satiated when it comes to the shape of stars.
Askar 170PHQ can effectively handle with problems of field
curvature and vignette.
Askar 107PHQ can capture tiny star objects due to its 749mm
focal length and astonishing field flattening capacity. When
used Askar 107PHQ and a high-resolution camera, it can still
bring out lots of detailed information of your target.
Askar 107PHQ is also a nice choice for your visual observa-
tion. It fits 1.25", 2" diagonal as well as various eyepieces
and can achieve a perfect focus. It can even be used to
observe planets with a super-high magnification eyepiece.
The sleek 107PHQ is assembled with high-quality CNC-ma-
chined components and wrapped with smooth coating. The
calm and seriousness is offset by the bright green decorative
rings or knobs. The 3.4" rigid focuser is capable of handling
a load of 8kg. It’s designed with a long travel distance of
95mm, which is suitable for visual observation. And it’s been
optimized especially for astrophotography.
