Gear Analysis

Askar 120APO

A professional-grade 120mm air-spaced triplet refractor designed for detailed deep-sky acquisition in a mobile workflow.

Field Performance

The Askar 120APO occupies a unique space in the refractor market. At 120mm, it provides the resolving power needed for smaller NGC galaxies and intricate nebula details while remaining light enough to be supported by mid-range strain wave mounts like the ZWO AM3.

Operating at a native 840mm (f/7), the demands on guiding are higher than a typical 80mm class scope. However, my testing showed that with proper balancing, the triplet objective produces exceptionally clean stars and high-contrast details across the entire frame.

Strengths
  • Pinpoint resolution for small targets
  • Robust 3.3" focuser handles heavy mono rigs
  • Manageable weight for mobile setups
  • Excellent color correction across LRGB
  • Sharper then my 8" SCT
Considerations
  • Requires dedicated flattener for imaging
  • Demands high-precision guiding at 840mm
  • Significant physical length requires large bags

Final Verdict

"The Askar 120APO is a high-resolution beast that still manages to play nice with portable setups. It offers an incredible 120mm imaging platform without the prohibitive weight of traditional high-end triplets."
