Whether you're looking through an eyepiece or imaging with an astronomical camera or a DSLR, you'll benefit from the lens design and compact form factor of the 65PHQ Quintuplet APO Telescope from Askar. It features a quintuplet air-spaced apochromatic lens system that eliminates the need to use a separate field flattener. The quint APO has two extra-low dispersion elements that dramatically reduce chromatic aberration. This design also eliminates the need to calculate back focus distance—just attach your camera with one of the three included adapters and you're ready for imaging. The f/6.4 focal ratio and 416mm focal length lend themselves to deep-sky photography, but add a diagonal with a high-magnification eyepiece and the scope is great for planetary observation.
- f/6.4 focal ratio and 416mm focal length allow for both deep-sky and planetary imaging.
- Quintuplet air-spaced apochromatic refractor design with two ED elements produces rich views with minimal chromatic aberration.
- APO is self-flattening, eliminating the need for a separate field flattener.
- 44mm image circle supports full-frame cameras.
- Sturdy 2.5" rack-and-pinion design can easily carry larger and heavier eyepieces, accessories like Barlows and focal reducers, and imaging systems
- 360° rotator with scales and finder base
- 10:1 fine adjustment ratio
- Anodized green handle and tube ring assembly, can be detached and reinstalled in seconds
- M6 screw holes on handle for attaching accessories
- Includes M68, M54, and M48 camera adapters
