Instead of buying extra flatteners, calculating the back focus of the flattener, or making a tedious connection to match the correct distance, astrophotographers can simply equip it with any possible imaging accessories, make the target stay at the focus, and then the whole optical system is perfect for imaging.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv align=\"center\" style=\"text-align: left;\"\u003e\n\u003cspan\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv align=\"center\" style=\"text-align: left;\"\u003e\n\u003cspan\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cspan\u003e65PHQ has a smaller size than other PHQ astrographs. 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv\u003e65PHQ comes with a telescopic lens hood, a high-quality CNC machined and painted tube, and attractive decorative parts.

M68, M54, and M48 camera adapters are also attached, and the M48 adapter has a 2” female thread for installing filters.\u003cbr\u003e \u003cbr\u003eIt is also a nice choice for your visual observation.
