Product Details

  • The Askar 80PHQ Quadruplet Refractor Telescope was designed to provide astounding images of our night sky.

    The Askar 80PHQ refractor telescope's lenses are arranged as an integrated lens combination, allowing for more accuracy and better imaging results. The long focal ratio of f/7.5 also helps control false color, meaning your stars will be sharp and free from the excessive color shifting often found in refractors with shorter focal ratios. The Askar 80PHQ offers a great combination of low weight, low bulk, low cost, and high image quality.

    Askar 80PHQ Super APO Refractor Telescope

    Thanks to the flatfield 3 + 1 quadruplet optical design of the 80PHQ, there is no need to add an additional flattener to adapt from visual to astrophotography. Because of this, there is no need to calculate back focus, making this telescope easy to use. The dual-speed 3" rack and pinion focuser allows for easy micro-adjustments for sharp full frame imaging with an image circle if 44mm.
