Instead of buying extra flatteners, calculating the backfocus of flattener or making tedious connection to match the distance, astrophotographers can simply equip it with any possible imaging devices, make the target stay at the focus, and then the whole optical system is perfect for imaging.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eHigh quality imaging optics:\u003c\/em\u003e\u003cbr\u003e130PHQ has an aperture 23mm larger than 107PHQ. 130PHQ has a focal ratio of f\/7.7 and a focal length of 1000mm. The Petzval-like quadruplet lens with two ED glasses offers excellent control of chromatic and other aberrations. With its self-flattening design, 130PHQ offers strong advantages in astronomical photography. It supports a medium frame 60mm image circle, has a fine spot diagram with only tiny distortion of the peripheral stars, and its central RMS radius is less than 2 microns.\u003c\/p\u003e\n\u003cp\u003eThe Askar 130PHQ is a true all-rounder with f\/7.7 - it is designed as a telescope for almost all applications:\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWith 1000mm focal length and the large corrected field of view, extended objects can be imaged. But equally, fine details of objects can be brought out when cameras with high resolution are used.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThe use of different cameras with different flange focal lengths is no problem.

This turns the flatfield apo into a wide field telescope or even a planetary telescope, depending on the eyepiece used.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003ePractical features:\u003c\/em\u003e\u003cbr\u003e130PHQ comes with a telescopic lens hood, a high quality CNC machined and painted tube and attractive decorative parts. The rigid 3.4\" focuser comes with M68, M54, and M48 adapters and a finder base. When used with the optional 3\" 0.7x flat field reducer, the telescope can reach a focal ratio of f\/5.4 and a focal length of 700mm, effectively reducing exposure time considerably. The multifunctional handle comes with a central slot for attaching an M6 screw with an M6 screw hole. It has a standard Losmandy style dovetail plate, together with sturdy double tube ring and is perfectly suited for both viewing and imaging.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eThe photographic 3.4\" Rack \u0026amp; Pinion focuser:\u003c\/em\u003e\u003cbr\u003eThe CNC focuser is optimized for photography and can handle a load of up to 8kg. The adjustment range is very generous. The focusing is done via rack and pinion which is decoupled from the bearing of the draw tube. This guarantees fine and precise adjustment even at maximum load. In addition to the 1.25\" and 2\" receptacle, the focuser also offers threads for screw on adaptations.\u003c\/p\u003e\n\u003cp\u003eEvery single APO is checked in the technical department before it is put into storage in order to guarantee its consistently delivered to you in the highest quality.\u003cbr\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eThe mechanics are tested and the focuser is optimally adjusted.\u003cbr\u003eThe lens is cosmetically checked and cleaned.
