The STC Filters Astro Nightscape Clip-Filter for Nikon APS-C cameras is a broadband filter designed to improve nightscape and astrophotography images by reducing the impact of light pollution. This filter is particularly effective for capturing nebulae, galaxies, and hydrogen nebulae, allowing for clearer and more vibrant photographs even in areas with significant artificial lighting. It is intended for photographic use only and is not suitable for visual observation.

The STC Filters Duo-NB Clip-Filter for Nikon (APS-C) cameras is a narrowband filter designed to enhance contrast in astrophotography by allowing only specific wavelengths of light to pass through. It targets important spectral lines such as hydrogen-alpha (H-a at 656 nm), oxygen (OIII at 501 nm), and sulphur (SII at 672 nm), making it ideal for capturing nebulae and other deep-sky objects. This filter is effective even in light-polluted environments or when the Moon is present, and can be used for both short and long-exposure photography.

The Steiner Ballistic Control Set is designed specifically for the Ranger 6 riflescope model with a 3-18x56 magnification. This set enhances shooting precision by allowing users to make accurate ballistic adjustments tailored to their specific shooting conditions. It is an essential accessory for marksmen who want to optimize their scope's performance for long-range accuracy.

The Steiner Ballistic Control Set is designed specifically for use with Steiner Ranger riflescopes, providing enhanced precision and control for long-range shooting. This set is compatible with the Ranger 4 series, which includes models with variable magnifications of 3-12x56 and 6-24x56. By integrating ballistic data and control features, it helps shooters make accurate adjustments based on distance and environmental factors.

The Steiner Ballistic Control Set is designed to enhance the precision and usability of specific riflescopes, namely the Ranger 8 models. It provides ballistic adjustments tailored for these scopes, allowing shooters to make accurate corrections based on distance and environmental factors. This set is compatible with multiple Ranger 8 riflescope variants, ensuring versatility for different magnification ranges.

The Swarovski tMA-50 clamping adapter is designed for users who want to attach night vision devices to their optics with precision and stability. This adapter is compatible with specific Swarovski night vision models and ensures a secure connection between your lens and night vision gear. Its robust construction and thoughtful design make it a reliable accessory for both field and tactical use.

This transmitted light spectroscope is a simple yet precise instrument designed for observing and analyzing the spectra of various light sources. It features a tube with a precision entrance slit and a 600 lines-per-millimetre grating, allowing users to easily point it at different light sources such as the sky (to observe the solar spectrum and Fraunhofer absorption lines), flames for chemical analysis, liquids for their absorption spectra, or the bright lines from discharge tubes and lamps.

This compact spectroscope features a high-performance flat-field concave grating in a module measuring just 136 x 120 x 75 mm and weighing 1.2 kg. It includes a built-in Lodestar X2 guide camera and an argon-neon calibration lamp for precise wavelength calibration. Both the input and output are equipped with T2 threads, making the unit compatible with most imaging cameras that use T2 thread connections. Starlight Xpress recommends pairing this spectroscope with the Trius SX-694 camera for optimal performance.
