Fast 70mm high-performance astrograph F5.5 for demanding astrophotographers and observers with 5 lens elements in 5 groups

• Very fast 70mm high-performance astrograph for demanding astrophotographers
• Due to the large lenses there is almost no vignetting
• Complex construction with 5 lens elements in 5 groups for absolute correction
• Needle-thin stars up to the edge of the image field even with 44 x 33 mm camera format
• Large, stable eyepiece extension, also suitable for heavy cameras
• Extremely high sharpness, colour purity and contrast thanks to SD lenses
• Very large field illumination up to 55mm
• High Strehl intensity of 96.7% at visible wavelengths
• Optional reducer available for even faster results
• Optional motor focuser with two speeds can be retrofitted

The powerful ED apo is suitable for observing and astrophotography with an high-contrast image.

• 150 mm aperture, 1200 mm focal length, focal ratio f/8
• High image quality thanks to extra-low dispersion glass FPL53 (Ohara, Japan) and matching glass from Schott
• Highly effective coating for maximum transmission and minimum reflections
• Large rack and pinion focuser with 11:1 reduction for sensitive focusing
• 360° rotation adapter
• Tube in traditional white - heats up less during the day and is more visible at night
