The Baader Planetarium FSIIHS-2 HighSpeed Narrowband CCD Filter, with the item number 2459399, is a high-quality tool designed for astrophotography enthusiasts and professionals alike. This filter is specifically designed for use with CCD (Charge-Coupled Device) cameras, which are commonly used in astronomical imaging.
The FSIIHS-2 filter is part of Baader's HighSpeed Narrowband series, which is renowned for its ability to efficiently block out unwanted light pollution and allow only the specific wavelengths of light required for astronomical imaging to pass through. This filter is particularly suited for capturing detailed images of nebulae and other deep-sky objects that emit light in the H-alpha and S-II spectral lines.
The FSIIHS-2 filter is made from high-quality optical glass and features a multi-coated surface to minimize reflection and increase light transmission. It has a thickness of 2.5mm, which helps to reduce internal reflections and increase contrast in your images. The filter is also threaded for easy attachment to your CCD camera, and it comes with a protective cap to keep the filter clean and dust-free when not in use.
In terms of specifications, the FSIIHS-2 filter has a transmission range of 656nm to 673nm for H-alpha and 671.7nm to 673.6nm for S-II. It has an OD (optical density) of 3.0 at H-alpha and S-II, which means it effectively blocks out 99.6% of light in these wavelengths. The filter has a diameter of 1.25 inches, which is the standard size for CCD cameras, and it has a 2" or 51mm thread for easy attachment.
Overall, the Baader Planetarium FSIIHS-2 HighSpeed Narrowband CCD Filter is a high-performance tool for capturing stunning images of nebulae and other deep-sky objects. Its high transmission, low reflection, and effective blocking of unwanted light make it an ideal choice for serious astrophotographers.
Pros of buying a FSIIHS-2 Baader Highspeed Narrowband CCD Filter:1. High Quality: Baader is known for producing high-quality filters, and this one is no exception. It is designed to block out unwanted light and allow only specific wavelengths through, enhancing your viewing experience of celestial objects.
2. Wide Bandpass: This filter has a wide bandpass, which means it can capture a broad range of wavelengths within the narrowband spectrum. This can make it easier to observe objects that may be faint or difficult to see with other filters.
3. Durable: The FSIIHS-2 is made of high-quality materials and is built to last. It is resistant to scratches and other damage, making it a good investment for serious astronomers.
4. Compatibility: This filter is compatible with a wide range of telescopes and imaging systems, making it a versatile option for many different setups.
Cons of buying a FSIIHS-2 Baader Highspeed Narrowband CCD Filter:1. Price: As a high-quality, professional-grade filter, the FSIIHS-2 is not cheap. It may be out of reach for some hobbyists or beginners with a limited budget.
2. Learning Curve: Narrowband imaging can be a complex and technical process. If you are new to astronomy or imaging, you may need to spend some time learning how to use this filter effectively.
3. Specific Uses: This filter is designed for specific types of celestial objects and for imaging. If you are primarily interested in visual observation, you may not get as much use out of it.
Conclusion:The FSIIHS-2 Baader Highspeed Narrowband CCD Filter is a high-quality option for serious astronomers and imagers. Its wide bandpass, durability, and compatibility make it a versatile and reliable tool. However, its price and specific uses may make it a less appealing option for beginners or those on a tight budget. If you are willing to invest in the learning curve and the cost, this filter can greatly enhance your observing and imaging experience.
Recommendation:If you are a serious astronomer or imager with a good understanding of the process and a budget to match, the FSIIHS-2 Baader Highspeed Narrowband CCD Filter is a worthwhile investment. If you are just starting out or have a more limited budget, you may want to consider a less expensive filter or focus on visual observation before making the leap to narrowband imaging.

Baader f 2 highspeed narrowband ccd filter with pre shift and PFC low profile cell: s-ii - Baader new filters are designed especially for the delicate requirements of extremely fast historiography optics, such as hyper star, Rasta, ultra-fast instruments from etc AP ass etc.
For the first time these filters allow effective use of extremely fast optics high contrast imaging emission nebulae. In spite of the typical line broadening with such fast optical trains they are able to deliver maximum contrast.

This can frequently take 4-6 weeks or more for several countries 8 Italy, Argentina, and south Africa Brazil. Therefore these filters have a cowl-pre shift which matches f 2 to 3 perfectly. Conventional narrowband filters cause a heavy loss in transmission due to the strong cowl-shift.
