Astronomik UHC-E Clip filter for Sony Alpha
If you photograph the night sky under conditions where light pollution keeps even experienced astrophotographers awake at night, the Astronomik UHC-E Clip filter for Sony Alpha is exactly what you are looking for. This filter slides directly into the camera body in front of the sensor - eliminating the need to buy a separate filter for each lens. One filter covers your entire Sony Alpha lens system.
What does the UHC-E filter do?
The UHC-E (Ultra High Contrast - Extended) filter from Astronomik transmits primarily the wavelengths characteristic of ionized hydrogen (H-alpha), oxygen (OIII) and sulfur (SII) emissions, while significantly suppressing the disruptive spectral components of sodium and mercury vapor lamps as well as modern LED lighting. The result is dramatically higher contrast of emission nebulae and planetary nebulae against the sky background.
Please note that the filter is primarily intended for photographic use. It is not suitable for visual observation through an optical or electronic viewfinder, as it significantly alters color rendering and reduces overall light transmission.
Clip mount - one filter for all your lenses
The Clip mount design is a solution appreciated by anyone working with multiple lenses during a single night. The filter simply slides into the Sony Alpha bayonet mount in front of the sensor, with no adapters or threaded step rings required. The frame is made from aluminum - rigid enough to hold the filter securely in place, yet light enough not to add unnecessary weight to the system.
The Clip design also has a practical impact when working with different focal lengths. If during a single night you switch between a wide-angle lens for panoramic Milky Way shots and a telephoto lens for a detailed view of a nebula, you do not need to move the filter between threads - it simply stays in the camera body and works with all lenses at once. This saves both time and money.
Who is this filter best suited for?
Astrophotographers shooting from suburban locations or cities will especially appreciate the filter's ability to suppress the orange glow caused by sodium lighting and the diffuse glare of modern LED lamps. The filter performs best when imaging emission regions such as:
- Orion Nebula
- Lagoon Nebula
- Rosette Nebula
- Heart and Soul Nebulae
When photographing star clusters or galaxies, where a continuous spectrum dominates, its benefit will be smaller - the filter also limits the transmission of the broad white light spectrum.
Quality and precision from a German manufacturer
Astronomik is a German manufacturer with a long tradition in the field of astronomical filters. Their filters are characterized by precisely defined transmission bands and high-quality optical glass with multilayer anti-reflection coatings that minimize unwanted reflections and ghost images. The Clip filters for Sony Alpha are also designed with the exact bayonet dimensions in mind, so mounting is smooth and safe with no risk of damage to the sensor or camera contacts.
