Star Tracker Evaluation: Sky-Watcher's Star Adventurer 2i Worthy Recommendation

Star Tracker Evaluation: Sky-Watcher's Star Adventurer 2i Worthy Recommendation

For those seeking a small, lightweight mount capable of handling DSLRs for wide-field astrophotography with more payload capacity to hold a telescope, several compelling options exist that balance portability and strength. Two of these options are the ZWO AM5N Strain Wave Equatorial Mount and the iOptron SkyGuider Pro.

The ZWO AM5N, weighing approximately 12 lbs (5.5 kg), is a lightweight equatorial and alt-azimuth mount that can carry up to 28 lbs (13 kg) without counterweights, making it ideal for medium-sized refractors or large SCTs. Adding a counterweight shaft and counterweight (sold separately) increases capacity to 44 lbs (20 kg) for even larger setups. This versatile mount functions as both an equatorial and alt-azimuth mount by adjusting latitude from 0 to 90 degrees, allowing imaging from anywhere on Earth.

The mount comes with a hand controller and can connect via WiFi or Bluetooth to apps like ZWO StarGazing for guided control and GoTo functionality. It includes a premium soft case for easy transport, making it well-suited for taking to dark sky sites. Additional features include a USB port for PC and ASIAIR connectivity, enhancing integration with advanced astrophotography equipment.

On the other hand, the iOptron SkyGuider Pro is ultra-portable and compact, supporting up to 5 kg (11 lbs). This mount is sufficient for DSLR cameras with wide-field lenses and small telescopes. Featuring an all-metal structure, near-silent tracking, and a built-in illuminated polar scope, it is great for star tracking with a simple interface and reliable engineering, making it popular among astrophotographers seeking portability. The SkyGuider Pro can be mounted directly on standard photographic tripods.

A comparison of the two mounts is summarised in the table below:

| Mount Model | Weight | Payload Capacity | Mount Type | Special Features | |----------------------|-----------------|--------------------------|-------------------|--------------------------------------------------| | ZWO AM5N | 12 lbs (5.5 kg) | 28 lbs (13 kg) - 44 lbs (20 kg) | Equatorial/Alt-Az | Dual-mode, app controlled, high payload, portable| | iOptron SkyGuider Pro| Very lightweight | 11 lbs (5 kg) | Equatorial | Compact, silent, illuminated polar scope |

The ZWO AM5N is highly versatile, making it one of the best lightweight mounts with a high payload capacity suitable for serious astrophotography involving DSLRs and larger telescopes. The iOptron SkyGuider Pro, on the other hand, is ideal for those prioritizing portability and simplicity but with a more modest payload. Lightweight mounts below these payloads may struggle with heavier telescopes but are often easier to transport.

The Star Adventurer 2i, while not equatorial, is another option for wide-field astrophotography. It can handle around 3 kg (7 lbs) in practice, despite a stated weight capacity of 5 kg (11 lbs). The Star Adventurer 2i comes with an illuminated polar scope that works in both hemispheres and can be used for time-lapses, with the ability to track faster or slower than the rate of the stars. A used Star Adventurer 2i is an excellent choice for a star tracker, given its relatively few moving parts.

In conclusion, the choice between the ZWO AM5N, iOptron SkyGuider Pro, and the Star Adventurer 2i depends on one's specific needs, whether that be portability, high payload capacity, versatility, or a balance of these factors. Each mount offers unique features and benefits, catering to various astrophotography requirements.
