65PHQ作为PHQ系列中口径最小的一款产品，即将上市。65PHQ采用f/6.4焦比，焦距为416mm。不同于其他PHQ望远镜的四片式结构，65PHQ为五片式光学镜片组合，前三片中有两片为ED玻璃，有着非常好的色差及其他像差控制能力。由于采用自平场设计，65PHQ在天文拍摄中具有很强的优势。它支持全幅影像圈，点阵图细腻，周边星点变形极小。

65PHQ, with its smallest aperture in the PHQ series, is coming soon. 65PHQ has a focal ratio of f/6.4 and a focal length of 416mm. Instead of the quadruplet structure of other PHQs, the 65PHQ is a quintuplet with two ED glasses which offers excellent control of chromatic and other aberrations. With its self-flattening design, 65PHQ offers strong advantages in the astronomical shooting. It supports the full-frame image circle and has a fine spot diagram with tiny distortions of the peripheral stars.

和Askar推出的一系列望远镜一样，同样无需计算后截距也无需另外购买平场镜。望远镜本体净重2kg，标准装重量2.8kg。刚性2.5英寸调焦器，带新型含刻度的360°旋转器以及寻星镜基座。附有M68/M54/M48拍摄接环，其中M48接环内侧带有2英寸滤镜螺纹。

There is no need to buying extra flatteners or calculating the back focus of the flattener for the 65PHQ. The OTA weighs 2kg, and the full package with tube rings, etc. weighs 2.8kg. The 2.5” rigid focuser comes with a new-type 360° rotator with scales and a finder base. M68, M54, and M48 camera adapters are also attached, and the M48 adapter has a 2” female thread for installing filters.
