GoldFocus Plus Collimation Focusing System
The GoldFocus Plus Collimation Focusing System
supports precision focus and collimation.
The GoldFocus Plus Focusing System for digital astronomical imaging is a
combination of a scientifically designed GoldFocus Plus Mask
and the GoldFocus
Analysis Software. The GoldFocus Plus Focusing System
works with most astronomical CCD cameras and over 400 DSLR camera models.
Achieve better focus and collimation faster than
ever.

"I used to think that I had accurate collimation of my AT8RC using the
'defocused star/concentric ring' test.
But after using GoldFocus Plus, collimation is tack sharp and has never been
this good.
GoldFocus Plus is the reason for it.
I will definitely be using GoldFocus Plus to collimate in the future." --
