- Large 122mm aperture; f/7 focal ratio and 854mm focal length; a great travel telescope for astrophotography and observation; and even some fainter deep sky objects due to the higher limiting magnitude;
- FPL-51 triplet apochromatic lens structure; the astro refractor telescope contains one piece of ED glass, for better correction of aberration, greatly reduce chromatic aberration and enhance the clarity & sharpness;
- Dual speed 2.5-inch toothed focuser with 1: 10 gear ratio; easy to achieve accurate focus; the dual speed focuser can provide two focusing speeds by using a set of co-axial knobs; for fast focusing and fine focusing;
- 300mm dovetail length; it can maintain the balance to the greatest extent; and more convenient in the adjustment process;
- Carrycase included; this telescope bag has a removable shoulder strap and hand-carry strap.
(Note: The bag is included in the OTA, so you needn't buy one separately. For extra accessories, pls choose our bundle set)

- 1-Inch Large Sensor with High Sensitivity: Equipped with the IMX533 color 1-inch chip, featuring a 3.76μm pixel size and over 80% quantum efficiency for excellent resolution. It also incorporates CMOS glow suppression technology to reduce residual glow and improve signal-to-noise ratio, delivering superior imaging performance;
- Adaptability to Low-Light/Light-Polluted Environments: When paired with dual narrowband filters, it enables clear imaging even in light-polluted scenarios, expanding the applicable scenes for deep-space photography;
- High Resolution with Flexible Adaptation: When matched with a short-focus lens or fast lens system, the 3.76μm pixels can easily resolve a 10-arcminute field of view, avoiding detail loss caused by overly small targets;
- Two-Stage TEC Efficient Cooling: The two-stage thermoelectric cooling design can lower the CMOS sensor temperature to 30°C below ambient temperature, significantly reducing dark current and sensor noise during long exposures to ensure pure image quality;
- Wide Cross-System Compatibility: Supports Windows, Linux, Mac OS, Chrome OS, and Raspberry Pi systems (via AstroDMx Capture). For Windows systems, it can also be compatible with professional astronomical software such as Sharpcap, N.I.N.A, and TheSkyX through the ASCOM driver, offering flexible operation;
- Standard GRBG Bayer Pattern: Adopts the industry-standard GRBG Bayer pattern for accurate color reproduction, compatible with mainstream astronomical image processing workflows and reducing the difficulty of post-processing color adjustment.
Note: The SV605CC has completed the product change to optimize the horizontal stripe, and the S/N serial number of the new product has been changed to S/N(B).
