Apochromatic Refractors

The 107PHQ is a transportable APO refractor for astrophotography with corrected field of view up to full frame sensor and for observation up to the highest magnification range.

• Aperture 107 mm - focal length 740 mm - focal ratio f/7
• 4-element Petzval system with color-correct triplet objective and a corrector lens built into the optical tube
• Stable 3.4" RAP focuser with micro-reduction and 360° rotation - adjustment range 110 mm
• Sufficient working distance for observing with 2" accessories and for photography
• Besides 1.25" and 2" the apo offers M48, M54, M68 and M86 threads for screw adaptions
• 44 mm image circle with full illumination and correction allow the use of large sensors with high resolution
• CNC tube rings with Vixen/EQ5 style dovetail bar and carrying handle
• Finder shoe for standard finder and mini guiding telescopes available
• High quality carrying case for optimal protection of the telescope
• Each Quadruplet Apo is inspected and its optics tested before shipping - you get an optimally adjusted telescope for successful photography and observation from the very beginning.

This long focal ratio flatfield apochromat support 60 mm image circle and does not need calculations for backfocus. If the image is sharp, the field is flat.

• 130 mm aperture, 1000 mm focal length, f/7.7
• Petzval like, self flattening design with two ED elements
• 3.4" dual speed focuser
• 2" and 1.25" receptacles, M68, M54 and M48 threads
• Retractable dew shield
• Losmandy style dovetail bar
• Handle
• Vixen type finder base

With the FMA180 Askar has created a triplet APO refractor with unique visual and photographic applications

• With just a few simple steps, the APO telephoto lens can be transformed into a compact astronomical telescope, a guide scope or a powerful spotting scope for landscape observation.
• Aperture 40 mm
• Air-spaced triplet ED lens for almost pure color image
• Photographic focal length 180 mm (with corrector) - focal ratio f/4.5
• 2" filter thread in front of the objective for nebula filters
• Focal length for observation 220 mm
• The photographic field of view is up to full frame size
• Precise helical focuser on the lens for accurate focusing - with locking mechanism
  T2 camera connection with 55 mm working distance (when used as telephoto lens)
• Weight only 395 grams
• Can easily be attached to the telescope instead of the finder
• Fits on any ball head - also ideal for mobile astrophotography with photo trackers like the Sywatcher Adventurer
• Ideally suitable also as mini guide telescope
• The FMA180 can be converted into a compact spotting scope for observation in just a few steps

The Askar 185APO is an apo refractor with 185 mm aperture, 1295 mm focal length and a focal ratio of 1:7 with many practical features.

• Aperture 185 mm - Focal length 1295 mm - Focal ratio f/7
• Triplet objective with one ED element
• Stable 3,5" RAP focuser with micro reduction, 360° rotation connection and 100 mm adjustment travel
• Sufficient working distance for observation with 2" accessories and for photography
• Flattener and two reducers available (0.8x)
• CNC clamps with dovetail bar (Losmandy) and carrying handle
• Two finder shoes

The very good correction and the self-flattening design make this small telescope a compact photo machine.

• Aperture 65 mm / focal length 416 mm / focal ratio f/6.4
• 5-element system with color clean triplet objective and two corrector lenses built into the tube
• Stable 2.5" RAP focuser with dual speed and 360° rotation
• Sufficient working distance for observation with 2" accessories
• Suitable photo adapters are included in delivery
• Illuminated image circle with very good correction up to full frame format
• CNC tube rings with Vixen style EQ5 dovetail bars and carrying handle
• Finder shoe for standard finder and mini guiding telescopes available
