Features :
- Optical Tube
- 80mm aperture
- f/17.5 focal ratio
- 1400mm focal length
- Refractor-style optical configuration
- Achromatic doublet lens design corrects spherical and chromatic aberration to produce accurate color fidelity without distortion across the entire field of view
- Sturdy and precise helical focuser has no backlash and won’t rotate eyepiece/imaging rig
- Carbon fiber optical tube reduces weight without sacrificing strength, and resists the expansion/contraction caused by temperature fluctuations which can cause internal lenses to move out of alignment and affecting image quality and focusing ability
Other Details:

- Integrated 12mm blocking filter
- 22mm clear filter aperture
- Tuned to 0.5-0.3Å for viewing prominence details
- Tuning knob allows for ±0.5Å wing shift for Doppler-shift compensation
- Markers at every 0.1Å for reference and repeatability
- LED indicators for power, warming, ready, and fault
- Integrated 4.3x Barlow lens
- Two-element telecentric lens design keeps light waves parallel to flatten the field of view and reduce parallax as magnification increases
