The **Hoya HXEVA105PRT 105mm EVO Antistatic Protector Filter** is a specialized filter designed primarily for astrophotography, particularly for capturing deep-sky objects like nebulae. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.
---
### **Pros**
1. **Antistatic Coating**
The filter features an antistatic coating that reduces the risk of dust and debris accumulating on the filter s surface. This is particularly useful in astrophotography, where even small particles can create distracting artifacts in long-exposure images. The coating helps particles slide off rather than stick, keeping the filter cleaner for longer.
2. **High-Quality Optical Performance**
Hoya is a reputable brand known for producing high-quality optical glass. The HXEVA series is designed with precision-ground elements to minimize chromatic aberration and maintain sharp, clear images across the visible spectrum. This is critical for astrophotography, where image quality directly impacts the visibility of faint celestial objects.
3. **Durability and Build Quality**
The filter is constructed from durable materials, including a robust metal frame and a scratch-resistant coating. The threaded design ensures a secure fit on most 105mm telescope or camera lenses, reducing the risk of misalignment or damage during use.
4. **Compatibility with Astrophotography Setups**
The 105mm size is standard for many astrophotography setups, including telescopes with reducer/corrector lenses (e.g., APM, Astro-Tech, or William Optics) and DSLR/mirrorless cameras with 105mm filter adapters. It is often used in conjunction with other Hoya astrophotography filters (e.g., the HXEVA or HXEVA II series) to enhance contrast and reduce light pollution.
5. **Easy to Clean**
The antistatic properties make the filter easier to clean compared to traditional filters. Users can wipe it down with a microfiber cloth and isopropyl alcohol without worrying about static attracting dust. This saves time and effort, especially for photographers who shoot frequently.
6. **Cost-Effective for Its Purpose**
While not the cheapest filter on the market, the HXEVA105PRT offers excellent value for astrophotographers who prioritize image quality and durability. It is positioned as a mid-range option that balances performance and affordability.
7. **Minimal Light Loss**
The filter is designed to have minimal impact on light transmission, ensuring that the sensor receives as much of the incoming light as possible. This is important for capturing faint objects like galaxies and nebulae, where light is already scarce.

### **Cons**
1. **Limited Use Beyond Astrophotography**
The HXEVA105PRT is optimized for astrophotography and may not offer significant benefits for terrestrial photography. While it can be used with cameras for general photography, its antistatic and optical properties are tailored to celestial imaging, making it less versatile for other applications.
2. **Potential Overkill for Beginners**
If you are new to astrophotography and primarily shoot bright objects (e.g., the Moon or planets), the cost of this filter may not be justified. For such subjects, a basic UV/IR cut filter or no filter at all might suffice. The HXEVA105PRT is more valuable for deep-sky imaging where contrast and cleanliness are critical.
3. **Thread Compatibility Issues**
While 105mm is a common size, some older or non-standard setups may require additional adapters or rings. Ensure your telescope or camera lens has a compatible 105mm filter thread (or can accommodate a step-down adapter) before purchasing. Failure to do so could render the filter unusable.
4. **No Built-in Light Pollution Reduction**
The HXEVA105PRT is not a narrowband filter (e.g., H-alpha, O-III, or S-II). If you shoot in areas with significant light pollution, you may need to pair this filter with a dedicated narrowband filter to enhance contrast for emission nebulae. The HXEVA series is more general-purpose and works well with broadband filters.
5. **Weight and Bulk**
The filter is relatively heavy and bulky compared to some other optical accessories. If you frequently swap filters or travel with your equipment, the added weight might be a minor inconvenience. However, this is a trade-off for the durability and performance it provides.
6. **Potential for Overuse of Features**
The antistatic coating is excellent for reducing dust, but it may not be necessary if you shoot in very clean environments or use a filter drawer. Some users might find that the benefits of the antistatic coating are outweighed by the cost, especially if they rarely encounter dust issues.

### **Conclusion**
The **Hoya HXEVA105PRT 105mm EVO Antistatic Protector Filter** is a well-engineered product tailored specifically for astrophotographers who prioritize image clarity, dust resistance, and durability. Its antistatic coating, high optical quality, and compatibility with standard astrophotography setups make it a strong choice for capturing deep-sky objects. However, it is not a versatile filter for terrestrial photography and may be overkill for beginners or those who primarily shoot bright celestial targets.
The filter excels in environments where dust and debris are concerns, and where maintaining image quality is paramount. If you are investing in a serious astrophotography setup and plan to shoot nebulae, galaxies, or other faint objects, the HXEVA105PRT is a worthwhile addition to your gear. For casual astrophotographers or those on a tight budget, it may be more practical to start with a basic UV/IR cut filter or a narrowband filter, depending on your specific needs.

### **Recommendation**
**Buy the Hoya HXEVA105PRT if:**- You are an astrophotographer who shoots deep-sky objects (nebulae, galaxies) and prioritize image quality and dust resistance.
- You use a 105mm setup (telescope or camera lens) and need a reliable protector filter.
- You frequently encounter dust or static issues in your shooting environment.
- You are willing to invest in a high-quality filter that will enhance your long-exposure images.
**Avoid or reconsider buying it if:**- You are a beginner in astrophotography and primarily shoot the Moon, planets, or bright objects.
- Your setup does not use a 105mm filter thread, or you lack the necessary adapters.
- You shoot in very clean environments where dust is not a major concern.
- You are looking for a narrowband filter to combat light pollution, as the HXEVA105PRT is not designed for that purpose.
- You are on a tight budget and can achieve similar results with a more basic filter.
For most dedicated astrophotographers, the HXEVA105PRT is a solid choice that justifies its cost through improved image quality and longevity. Pair it with other Hoya filters (e.g., HXEVA or HXEVA II series) for optimal results in deep-sky imaging.
