Short:
- apeture 80 mmLarge focal 560 mm
- Objective with 2 elements with FPL53 Ohara (Japan) and an element with the Lantahane for a perfect color image!
- Internal deflectors for a larger and less thoughtful contrast
- R & P Double Speed R & P Porte of 2.5 "
- Possible motorization without problems
- M63X1 female thread - flowing 2 "and 1.25"
- Excellent telescope also for observation with very contrasting images
- Retractable fogger
- Delivered with CNC ring.
- Each refractor is inspected and tested visually and mechanical before shipping
- It is possible to reduce the focal distance of 80 Apo and with its dedicated 0.8x reducer that you find among the recommended products, this allows you to reduce the focal distance to 450 mm and have a ratio equal to F / 5, 6

80mm F7 Artesky Apochromatic
Artesky presents the new line of APO refractors with 2 elements, the first is an element of the FPL53 Ohara (Japan) while the second is an element in the Lantane
It is possible to reduce it the focal length of a 0.8x factor to reduce the focal length to 450 mm for an F/D 5.6 or to use it at full focal distance with 1x corrector.
This new APO guarantees a high chromatic correction thanks to a precise and neat construction, both in the production phase and in the sales phase; The image does not suffer from any chromatic aberration and remains very clear and well contrasted.
APO Extra Low-Dispersion
This APO refractor manages to reach very high color levels thanks to the combination of two optical glass, the first is a FPL53 Ohara (Japan) element while the second is an element in the Lantane, this combination produces a product without chromatic error for Thus obtain much more efficient results than a doublet equivalent to the market.
