Telescopes

The main NJ scope is a 12.5" diameter-mirror modified Dall-Kirkham Cassegrain (iDK made by AG Optical, f/6.7, FL 2130mm). The telescope sits on a Paramount-MX equatorial mount, on a permanent pier in my observatory (see NJ Observatory gallery).
The telescope in Chile currently is a Planewave 24" CDK (a Dall-Kirkham Cassegrain design) at f/6.5. Images before 2022 used a Planewave 16" f/7. Both of these telescopes employ a field flattening lens after the secondary mirror in the light path to optimize for imaging.
