CTIO Seeing Monitor

DIMM2 is an Automatic Site Monitor mounted on top of Cerro Tololo InterAmerican Observatory since 2000 originally named RoboDIMM.


It is based on a MASS-DIMM instrument attached to a Meade 35cm carbon fiber Optical Tube (rescued from an RCX-400 tel. and customized by NOAO-CTIO) mounted on an Astro-Physics 1100GTO mount.


The CCD is a Prosilica GC650 GigE.


The dome was fully developed and built by NOAO-CTIO.
