GoldFocus High-Precision Focusing System
The GoldFocus High-Precision Focusing System supports high-precision focus but not collimation.
| If you are instead interested in a GoldFocus Plus Collimation Focusing System, which supports both focus and collimation, then click here. |
The GoldFocus Focusing System for digital astronomical imaging is a combination of a scientifically designed GoldFocus Mask and the GoldFocus Analysis Software. The GoldFocus Focusing System works with most astronomical CCD cameras and over 400 DSLR camera models.
Achieve better focus faster than ever.
