The **Nisi Optics N-852834 JetMag Pro FS ND64 1.8 MaxMag Magnetic Filter** is a cutting-edge, high-performance neutral density (ND) filter designed specifically for astrophotographers and advanced astronomers seeking to maximize the efficiency and precision of their deep-sky imaging sessions. Engineered with Nisi Optics signature commitment to optical excellence, this magnetic filter combines a **6-stop (ND64) neutral density attenuation** with a **1.8x magnification correction** to deliver unparalleled clarity and detail in long-exposure astronomical photography. The **JetMag Pro FS** series leverages Nisi s proprietary **Fresnel surface technology**, which minimizes weight while maintaining exceptional optical quality, making it ideal for use with large-aperture telescopes and high-resolution cameras. Its **magnetic mounting system** ensures quick and secure attachment to compatible telescopes, eliminating the need for additional adapters or filters rings, thus reducing potential light loss and alignment issues. The filter s **high-transmission coating** is optimized to preserve the full spectrum of light, from deep red to near-infrared, ensuring that critical emission lines such as those from hydrogen-alpha, oxygen-III, and sulfur-II are captured with maximum fidelity. Whether paired with a dedicated astrophotography camera or a modified DSLR, this filter excels in capturing faint nebulae, galaxies, and supernova remnants with enhanced contrast and reduced overexposure, even under challenging light-polluted skies. Built to withstand the rigors of field astronomy, the JetMag Pro FS is constructed from durable, lightweight materials, making it a reliable companion for both observatory-based and portable setups. For astrophotographers pushing the boundaries of their imaging capabilities, the N-852834 JetMag Pro FS ND64 1.8 MaxMag is an indispensable tool, offering a seamless blend of advanced optical engineering and practical functionality to elevate the quality of their cosmic imagery.
### **Pros and Cons of the Nisi Optics N-852834 JetMag Pro FS ND64 1.8 MaxMag Magnetic Filter**
#### **Pros:**1. **High-Quality Construction** The JetMag Pro FS is built with durable materials, including a robust metal housing and high-grade glass elements, ensuring longevity and resistance to wear.
2. **Magnetic Mount System** The magnetic design allows for quick and easy attachment to most camera lenses, eliminating the need for additional adapters in many cases. This is particularly useful for photographers who frequently switch lenses or work in dynamic shooting environments.
3. **Optical Performance** The ND64 filter provides a neutral density of 6 stops, which is ideal for long-exposure photography, slow shutter speeds in bright conditions, or achieving a shallow depth of field in daylight without overexposing the sensor. The 1.8 MaxMag version is optimized for lenses with a maximum aperture of f/1.8, ensuring minimal vignetting and optimal light transmission.
4. **Minimal Vignetting** The MaxMag version is designed to reduce edge darkening, making it suitable for wide-angle and fast lenses where vignetting can be a concern.
5. **Easy to Use** The magnetic attachment is intuitive, and the filter can be quickly swapped in or out without tools. This is convenient for field photographers or those who prefer a hands-free approach.
6. **Versatility** The ND64 filter is useful for a variety of genres, including landscape, architectural, and street photography, where controlling exposure without adjusting ISO or aperture is beneficial.
7. **No Thread Damage** Since the filter attaches magnetically, it avoids the risk of stripping lens threads that can occur with screw-in filters.
#### **Cons:**1. **Compatibility Issues** While the magnetic mount works with many lenses, it may not fit perfectly on all camera bodies or lenses, especially those with very large or irregularly shaped lens mounts. Some photographers report slight misalignments or difficulty attaching it to certain lenses.
2. **Potential for Dust and Debris** The magnetic attachment can sometimes attract dust or small particles, which may require occasional cleaning. Additionally, if the filter is not stored properly, the magnetic strength may weaken over time.
3. **Limited to Magnetic Lenses** The filter cannot be used on lenses without a compatible magnetic surface, such as some older or specialty lenses. This may limit its usefulness for certain photographers.
4. **No UV or Skylight Protection** This is a pure ND filter and does not provide additional protection against UV rays or haze, which some photographers prefer in a single filter.
5. **Price** Compared to traditional screw-in ND filters, the JetMag Pro FS is relatively expensive, especially if you already own a collection of screw-in filters. However, it can be a cost-effective solution if you frequently use ND filters and want to avoid buying multiple screw-in versions.
6. **Potential for Misalignment** If the lens or camera body has a strong magnetic field (e.g., some DSLRs with powerful motors), the filter might not stick securely, leading to potential misalignment or accidental detachment during use.

### **Conclusion and Recommendation**
The **Nisi Optics N-852834 JetMag Pro FS ND64 1.8 MaxMag** is a high-quality, versatile ND filter that excels in scenarios where quick attachment, minimal vignetting, and reliable performance are priorities. Its magnetic design is a significant advantage for photographers who frequently switch lenses or work in dynamic environments, as it eliminates the need for additional adapters and reduces the risk of thread damage. The ND64 density is well-suited for long-exposure photography and achieving creative effects in bright conditions without sacrificing image quality.
However, the filter s compatibility with all lenses is not guaranteed, and its magnetic attachment may not be ideal for every photographer s workflow. If you primarily shoot with a fixed lens setup or work in environments where dust and debris are concerns, a traditional screw-in ND filter might be a more reliable choice. Additionally, if you require additional protection (e.g., UV or skylight), you may need to pair this filter with others.
**Recommendation:**- **Buy it if:** You frequently use ND filters, work with fast lenses (especially around f/1.8), prioritize quick attachment/detachment, and want to avoid thread damage. It s also ideal for photographers who shoot in diverse conditions and need a flexible solution.
- **Avoid it if:** You have lenses that don t support magnetic mounts, prefer a single-purpose filter with additional protection (e.g., UV), or work in environments where dust and magnetic interference are significant concerns. In such cases, a high-quality screw-in ND filter might be more practical.
For most photographers who value convenience and optical performance, the **Nisi Optics JetMag Pro FS ND64 1.8 MaxMag** is a strong recommendation, especially when paired with compatible lenses. However, always test its fit on your specific gear before committing to ensure it meets your needs.
