Revolutionary f/2 Speed for Faster Astrophotography

The standout feature of the HAC125DX is its lightning-fast f/2 focal ratio, allowing significantly shorter exposure times compared to slower astrographs. This means:

• Capture more detail in less time

• Improve efficiency during imaging sessions

• Reduce the need for autoguiding in many situations

• Maximise productivity under limited clear sky conditions

This speed makes it ideal for capturing nebulae, star fields, and wide-field deep-sky objects.

Advanced Honders Catadioptric Optical Design

The HAC125DX uses a sophisticated Honders Advanced Catadioptric (HAC) optical system, combining refractive and reflective elements to optimise performance. This hybrid design delivers:

• Exceptional sharpness across the field

• Excellent contrast and clarity

• Compact physical size compared to traditional astrographs

• High optical efficiency

The Mangin mirror and premium coatings ensure maximum light transmission and image quality.

Compact and Portable Grab-and-Go Astrograph

Measuring just 40cm in length and weighing only 3.82kg, the HAC125DX is ideal for portable astrophotography setups. Its compact design makes it perfect for use with lightweight equatorial mounts and travel setups.

Simply attach it to your preferred mount and begin capturing the night sky quickly and easily.

Enhanced Focusing System for Modern Astronomy Cameras

The HAC125DX improves upon previous models with a rear primary mirror helical focuser, providing:

• Easier and more precise focusing

• Improved compatibility with a wider range of cameras

• Stable imaging performance

The 16mm image circle is ideal for popular astronomy sensors such as IMX533 and IMX585.
