Sony Camera A6400a Super UV/IR-Cut (75023)

The Sony A6400a Super UV/IR-Cut is an astromodified version of the Sony A6400 camera, optimized for astrophotography. In standard cameras, a filter is used to block much of the red spectrum to match human color perception in daylight, but this also blocks the crucial H-alpha emission line, which is important for capturing astronomical gas nebulae. The Super UV/IR-Cut astromodification replaces the original filter with one that allows the full visible spectrum (400–700 nm) to reach the sensor, greatly increasing the camera’s sensitivity to H-alpha and SII emissions. This makes the camera especially well-suited for photographing faint nebulae and other deep-sky objects while still allowing for normal daytime use with a custom white balance.

Astromodification Benefits and Features

• The Super UV/IR-Cut filter modification enables the camera to capture all visible light, from 400 nm to 700 nm, with high transmission efficiency.

• This increased sensitivity allows for detailed imaging of gas nebulae and other astronomical features that are difficult to photograph with an unmodified camera.

• The camera’s large APS-C sensor is ideal for capturing wide and detailed views of extended nebulae.

• The camera remains user-friendly and portable, with a built-in monitor and no need for an external computer or power supply.

• Autofocus and regular photography functions are retained, and a custom white balance can be set for daytime use.

Types of Astromodification Available

• Baader Astromodification: Uses a Baader BCF filter, transmitting 420–680 nm and increasing H-alpha sensitivity by about four times compared to an unmodified camera.

• Super UV/IR-Cut Astromodification: Uses a filter that transmits the full visible spectrum (400–700 nm), maximizing light collection for astrophotography.

• Full Range Astromodification: Extends sensitivity into the ultraviolet and infrared (starting at 300 nm), offering flexibility for different imaging needs.

Included in Delivery

• Camera body

• Battery

• Charger

• USB cable

• Manual

Additional Notes

• During the astromodification process, the original packaging is opened and the camera is tested, so the shutter count will not be zero. However, the camera is not used for regular photography and is sold as new unless otherwise specified.

• The modification is performed by specialists, such as AstroHobby in Italy, to ensure quality and reliability.
