Features 5

• 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.
• Its especially amateur or beginner friendly since you dont need to attach an extra field flattener to get a satisfactory picture. And for the fact that you dont 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, 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 standard package includes an Askar 107PHQ OTA, a set of four-piece M86-M48 adapters, a pair of tube rings, a 300mm Askar Vixen-style dovetail plate and a high-quality aluminum suitcase.
