1.3m DFM Telescope was installed at the Indian Institute of Astrophysics
DFM Engineering recently installed a 1.3m F/8 Double Horseshoe telescope at the Vainu Bappu Observatory (VBO) at the historical Indian Institute of Astrophysics (IIA) near Bangalore, India.
The installation required extensive planning and design by DFM as documented in the following article.
Exciting observations such as the Comet ISON are already being captured by the staff at the IIA.

Dr. Frank Melsheimer of DFM Engineering presents an investigation of Satellite
Dr. Melsheimer addresses the particular demands placed upon a telescope as it tracks artificial satellites.
Multiple white papers are referenced in his study as he investigates the configuration, mechanical and
servo drive considerations of the satellite tracking telescope.
In this analysis, Dr. Melsheimer provides an explanation of the three types of mount configurations; Alt-Az,
Alt-Alt, and the Equatorial mount and identifies significant features.
He addresses the mechanical considerations of the optical tube assembly mount position, drive stiffness
and structural stiffness as well as the servo drive system.

Memorial University Grenfell Campus features a DFM Engineering 24" Telescope!
A new 24" DFM Engineering telescope was installed at the Grenfell
Campus of Memorial University.
Installation took place in the late afternoon and evening hours before an approaching storm.
The new observatory and telescope will provide handicapped accessibility for the public and with research
support from NSERC (NSF equivalent) the telescope will be used for research on half-light diameters of
open clusters. The Grenfell Campus will also explore collaborative projects with students from Saint Mary's
University in Halifax, which has a full-blown astronomy graduate program.

DFM Engineering's Articulated Relay Eyepiece (ARE-125)
provides revolutionary access to telescope viewing for handicapped stargazers at the Smithsonian
Institution's National Air and Space Museum Observatory.
Last August the National Air and Space Museum (NASM) featured a special program at the Public Observatory
for a family with the Make-A-Wish Foundation.
Matthew, in a wheelchair, wished to look through a powerful telescope to see the awesome and inspiring
images of the universe! The DFM Engineering creation of the Articulated Relay Eyepiece (ARE-125 )
helped make his wish a reality by providing the accessibility.
