AG Optical Systems is excited to offer a quartz upgrade option on all of our telescope offerings. Quartz' extremely low coefficient of thermal expansion greatly improves a mirror's ability to resist changes in its figure as ambient temperatures change. The end result is that you can spend more time imaging and less time waiting for the scope to cool. We are offering special quartz upgrade pricing for a limited time: $600 for a 12.5" iDK and $1000 for a 17" iDK.
Please visit the AG Optical Systems website to learn more.
