Innovations Foresight On-Axis Guider (ONAG)
By Frank Colosimo
Guiding is one of those necessary evils for high quality astro imaging. One camera company, SBIG, offers cameras with a built-in guide chip, but some of their cameras and all others require some kind of external guiding. The two main external guiding options up till now have been 'guide-scope guiding' and 'off-axis guider guiding'. The ONAG (on-axis guider) from Innovations Foresight provides a new third option with unique features that combines the best qualities of both guide scopes and off-axis guiders. I was looking for a better guiding solution and was very interested to see if this new guiding product would work out.
