Telescope Accessory Celestron CE93323 Aluminium Black 3.2 cm Focal Length

The Celestron CE93323 Aluminium Black accessory is a compact telescope component crafted from durable aluminum with a matte black finish. With a fixed focal length of 3.2 cm, this optical accessory is designed to modify the effective focal properties of compatible telescopes and to help achieve clearer, higher-contrast views of celestial objects. Its lightweight metal construction provides rigidity while keeping additional load on the telescope minimal.

Advantages

The aluminium construction ensures corrosion resistance and structural stability for repeated use in field conditions. The fixed 3.2 cm focal length delivers predictable optical performance and easy integration into observing setups. The black finish reduces internal reflections and stray light, improving image contrast when observing planets, the Moon, and brighter deep-sky objects.

Suitable for

• Planetary and lunar observation where higher magnification and contrast are required
• Use with refractor and reflector telescopes that accept standard accessory mounts
• Amateur astronomers seeking a lightweight, durable focal accessory for night sky viewing

Key specifications

• Material: aluminium
• Color/finish: black (matte)
• Fixed focal length: 3.2 cm
• Purpose: optical focal accessory to alter effective focal characteristics
• Construction: lightweight, rigid metal housing

How to use

Install the accessory according to your telescope’s accessory mounting method, ensuring a secure mechanical connection and proper alignment with the optical axis. After mounting, focus the telescope slowly while observing a bright object to find the sharpest image. Fine-tune focus and, if applicable, retarget the telescope to the desired celestial object. Remove or replace other optical elements only when the telescope is secured to avoid damage.

Usage recommendations

For best results, use the accessory in stable atmospheric conditions and combine it with appropriate eyepieces for your telescope’s aperture and focal ratio; always handle the aluminium surfaces with a soft cloth to keep optical interfaces free of dust and fingerprints.
