The AC 152/900 optics: This 6" refractor is the ultimate telescope for wide-field observations and narrow-band photography.
It is a great alternative to normal achromats and offers features that are not normally found in this class:
- The objective has better colour correction than a comparable achromatic lens. In Japan, this refractor is even sold as a semi-apochromatic under the name Nerius. The lenses of the 2-element objective are K9 and F4.
- A 2.5" rack and pinion focuser with many auxiliary threads. You can also attach screw adaptors for astrophotography via the M63 internal thread. You will find suitable adaptors in the accessories section.
- The refractor is still portable. Thanks to the retractable dew shield, the telescope has a transport length of only 800 mm and thus fits on any back seat.
Areas of application:
- Moon and planets With very bright objects, the remaining colour error of the optics is noticeable. The "Contrast Booster" filter helps here by increasing contrast and sharpness.
- Observation of nebulae, star clusters and galaxies: The great strength of the refractor is wide-field observation. Contrast and sharpness in this area of application are comparable to those of an APO.
- Deep sky astrophotography: You can also do this with this refractor. We offer suitable field correctors. However, we recommend filters that reduce colour aberration, such as narrow-band filters or H-alpha filters.
It not only matters which telescope you buy but also where you buy it. Our additional services:
- We are a leading telescope dealer and know the devices we sell. Our customer service team will gladly help you after your purchase if you have problems with assembly or operation.
- We provide a copy of the 80-page Telescope ABC beginners handbook with every telescope.
