FF110 APO Refractor
The ZWO FF110 APO Refractor is a lightweight, compact instrument engineered for immersive visual observing and high-performance astrophotography.
*Focus can be achieved within a back focus range of 42–73 mm, measured from the M54–M48 interface shoulder.
Main Features
Flexible Connectivity for Multiple Configurations
Uniqueness
1. Four-Element Optical Design
The optical design features four elements. These are fully air-spaced and apochromatic for superior results.
All four elements work together to deliver a flat imaging field without the need for an additional field flattener.
One ED (extra-low dispersion) glass element is incorporated to effectively reduce chromatic aberration and improve clarity.
2. 44 mm Image Circle — Full-Frame Support
With a 44 mm image circle, this refractor telescope fully supports full-frame sensors and a wide range of imaging setups.
It delivers sharp star fields with excellent edge-to-edge performance, ensuring consistent quality across the frame.
3. Native Flat-Field Design
The FF110 APO features a native flat-field optical design, eliminating the need for an additional field flattener.
No complex back focus calculations are required—simply attach your camera and start capturing once focus is achieved.
This system pairs perfectly with the asiair pro for streamlined control of your astrophotography sessions.
Convenient Design
4. Coarse & fine focus adjustment
Equipped with a rigid 3-inch rack-and-pinion focuser, this telescope offers precise 1:10 dual-speed control.
A built-in 360° rotator at the rear allows for smooth and accurate camera angle adjustments for perfect framing.
5. Retractable Dew Shield
The telescope features a retractable dew shield, reducing overall length for improved portability during transport.
Precision CNC machining and a high-quality finish, combined with internal anti-reflection coating, minimize stray light.
6. Quick-Release Mounting Rings
The mounting rings are detachable, allowing for quick and easy setup or teardown of the telescope in the field.
7. Photography Extension Tube
The FF110 APO includes a photography extension tube with a 2-inch filter thread and standard rear adapters.
Supported standards include M48×0.75 and M54×0.75, allowing for easy integration with many imaging accessories.

AM5N Harmonic Drive Mount
The ZWO AM5N Harmonic Equatorial Mount is a next-generation harmonic drive telescope mount designed for serious astrophotography and advanced visual observing. Combining strain wave gear technology, lightweight portability, and high-precision tracking, the AM5N delivers professional-level performance without the bulk of traditional equatorial mounts.
If you're searching for a lightweight equatorial mount with no counterweight required, exceptional tracking accuracy, and full ASCOM compatibility, the ZWO AM5N is one of the most advanced portable mounts available today.
Harmonic Drive (Strain Wave Gear) Technology
The AM5N uses a 300:1 reduction ratio strain wave gear system combined with synchronous belts and precision stepper motors to provide smooth, backlash-free tracking.
Periodic Error: < ±10"
Resolution: 0.17 arcseconds
PE Cycle Duration: 288s
Max Slew Speed: 6°/second
This makes the AM5N ideal for long-exposure deep sky astrophotography, high-resolution planetary imaging.
High Payload Capacity – No Counterweight Needed
Despite weighing only 5.5 kg (12.1 lbs), the ZWO AM5N supports:
15 kg (33 lbs) without counterweight
20 kg (44 lbs) with counterweight
This allows you to mount refractors, astrographs, or compact SCT setups without the complexity of heavy counterweight systems. For portable astrophotographers, this is a major advantage.
Dual Mount Modes: Equatorial & Alt-Az
The ZWO AM5N operates in:
Equatorial Mode (EQ) – optimized for astrophotography
Alt-Az Mode – ideal for visual observing and outreach
Latitude adjustment range: 0° – 90° Azimuth adjustment: ±6°
Compatible with both Losmandy and Vixen dovetail saddles.
Full Connectivity & Smart Integration
The AM5N supports:
ASCOM
LX200 protocol
USB connectivity
Wi-Fi
Bluetooth
ST4 Autoguider Port
Integrated cable management keeps your setup clean and organized.
Built for Extreme Conditions
Operating temperature: -20°C to 40°C
Perfect for winter astrophotography sessions.
⚠ Recommended input voltage: 12V If voltage drops below 10.8V, the mount will emit an under-voltage warning beep. For optimal performance, use the official ZWO power adapter and properly rated power cables.
It is recommended to use a counterweight of ≤5 kg. When using a 5 kg counterweight, the lever arm should be installed within the range of 20 cm to 30 cm.
For counterweights of other masses, the installation position can be calculated as follows:
Assume the counterweight mass is m kg. The allowable lever arm length L is defined by:
10 N·m ≤ m × g × L ≤ 15 N·m
where g = 9.8 m/s², which can be approximated as 10 m/s². For example, if a 2 kg counterweight is used, the allowable range of L is from
10 N·m / (2 × 10 m/s²) = 0.5 m to
15 N·m / (2 × 10 m/s²) = 0.75 m.

Comparing head to head with Vortex DiamondBack, Pentax and Zeiss Terras, these 8x42s do very well at a significant savings. Well, the Zeiss pair is better, but only expected! For the money, these would serve anyone very well.
Products as described, arrived 3 days before due date.
This is a great deep sky scope, and I am looking forward to getting some great pictures with it, all I need now are some clear skies (it's raining at the moment)

1) Permet de sceller le tube optique. Une touche de graisse de silicone pure, de qualité, celle pour les équipements de plongée assure l’étanchéité.
2) Empêche les contaminants de s’infiltrer
3) Empêche l’effet cheminée lorsqu’on change un oculaire ou un accessoire par temps froids.
4) Combiné à une isolation thermique de l'OTA un isolant thermique à double face genre REFLECTIX, permet de sortir l’instrument d’un local chauffé vers la température frigide extérieure pour observer immédiatement sans attendre l’équilibrage des températures.
J’ai testé de 25C à 5C, sur deux nuits à l’oculaire clavé 10mm dès l’installation 5 minutes après la sortie de l’instrument, l’image est absolument nette avec seulement la turbulence d’un seeing de 3-4, et ce durant toute la durée de la séance.

Les photos sont un stack des images brutes stabilisé de PIPP, et l'autre un léger traitement dans Registax 6.
Le 27 octobre vers 21h30 5 à 10 minutes après avoir sorti l’instrument, viewing 3/5. Hier avec barlow QT 2,25x Baader, résultat similaire. C'est ce que j'espérait, les tests se poursuivre.

Beautiful results without the complexity of traditional gear.
The ZWO Seestar S30 Pro is a compact, user-friendly smart telescope that makes deep-sky astrophotography surprisingly accessible. Its 30mm quadruplet APO optics and dual Sony sensors (IMX585 + IMX586) deliver sharp 4K images of nebulae, galaxies, and the Milky Way with minimal effort. Setup takes minutes: point it, select a target in the app, and it handles focusing, tracking, and stacking automatically. Ideal for beginners and casual imagers who want beautiful results without the complexity of traditional gear. Highly recommended.
