The telescope was manufactured by DFM Engineering.

The main telescope is equipped with a five-port instrument box. On-axis, there is an on-axis ZWO CMOS Planetary CMOS camera with a NxM arcmin field of view. On another port, there is room for a dedicated off-axis auto-guider. The other three ports are reserved for other instrumentation and detector design.

The finderscope is equipped with a ZWO Deep-Sky CMOS camera which helps with calibration and is capable of auto-guiding the main telescope.

More than twenty filters are available that cover wide and narrow bands from the infra-red (IR) to the ultra-violet (UV).


The original imaging system attained first light on August 16, 2000, and the wide-field imaging system attained “second light” on September 23, 2004. The present configuration, described above, brought us to a “third light” in the late summer of 2022.
