Astro-Physics 160mm EDF StarFire f/7.5 with 900GTO


This 160mm StarFire EDF was designed from the ground up as a brand new instrument, not a mere modification of one of our earlier products.

Lens: Our exceptional, multi-coated triplet, air-spaced apochromat uses the latest in multi-coating technology with the highest grade of optical glass to achieve exceptional image brightness and excellent color correction. The close air-spaced design results in rapid cooldown during nighttime temperature swings. Color correction is ideal for all visual and imaging needs. The 1200mm focal length allows a full range of eyepiece designs from simple to complex to produce extremely sharp planetary images. Performance has already become legendary among imagers.

Tube assembly: Multiple baffles reduce stray light to a minimum. The lens resides in a push-pull cell that maintains its collimation even under conditions of vibration during shipping. The new sliding dewcap has a built-in baffle to help prevent dew as well as block stray light.
