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.
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 80PHQ is a very transportable APO refractor for astrophotography with corrected field of view up to full frame format and for observing up to the highest magnification range.
Aperture 80 mm / focal length 600 mm / focal ratio f/7.5 4-element Petzval system with color clean triplet objective and one corrector lens built into the tube Stable 3" 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 High quality carrying case for optimal protection of the telescope Each Quadruplet Apo is inspected upon receipt, you will receive an optimally adjusted telescope for successful photography and observation from the very beginning.
The ASKAR APO 60 mm f/5 Quintuplet Apochromat from Sharpstar is optimized for wide field astrophotography with high resolution cameras
The ASKAR APO 72 mm f/5.6 quintuplet apochromat from Sharpstar is optimized for astrophotography with high resolution cameras
The ASKAR FRA 500/5.6 APO quintuplet apochromat from Sharpstar is optimized for astrophotography with high resolution cameras
With the FRA600 F/5.6 quintuplet astrograph, Askar has created a pure-color apochromat for astrophotography with large sensors.
This telescope is ideal for capturing stunning wide-field images of the deep sky over a 36 mm (APS-C) image circle. Sextuplet refractor with 100 mm aperture and f/5.5 focal ratio Flat field across a 36 mm image circle Two ED elements virtually eliminate chromatic aberration Rotatable 3.4 " dual speed focuser, M90-M54 and multiple threaded adapters, 2? adapter ring Fixed back focus - if the image is sharp, it is also best corrected. Transport length 482 mm, 4.3 kg weight Includes mounting rings, Vixen-style dovetail, carrying handle, finder shoe, and hard case TS Quality Guarantee: Each APO is individually checked (cosmetically, mechanically and visually) before shipment and comes with a complete checklist.
High-End APO refractor with image free from chromatic aberration and best mechanics for demanding observation and astrophotography.
