Askar全新发布3英寸0.7×全画幅减焦镜，可适用于107PHQ与
130PHQ。采用三片式设计，其中一片为ED玻璃。减焦系数为0.7×，
搭配107PHQ时焦比缩至f/ 4.9, 焦距减少至524mm。减焦镜与摄星
镜搭配使用时，能有效缩短曝光时间，使得拍摄视场更宽广，为您广
域深空的创作带来更多的便利与可能。后截距为标准的55mm，配有
M68，M54，M48三种尺寸螺纹接环，接驳方便。
Askar’ s new-launched 3” 0.7x full-frame reducer adapts for
107PHQ & 130PHQ. It has a triplet design with one ED glass. The
0.7x reduction gives 107PHQ a shortened focal ratio of 4.9 and a
shortened focal length of 524mm. This reducer, connected with the
astrographs, can effectively shorten the exposure time and
dramatically increase your field of view, bringing more convenience
and possibilities for your deep-sky astrophotography. The backfocus
is the standard 55mm. It comes with three thread adapters of M68,
M54, M48 , so it is convenient for connection.
