Home Observatory: Background

After 11 years of visual astronomy, traveling to darker skies and hoping for good weather were yielding too few actual nights under the stars. It was time to build a home observatory: The Robservatory was born.

By far, the biggest challenge for amateur and professional astronomers worldwide is the rapid and relentless disappearance of dark skies as a result of light pollution. To counter this effect, the imaging of certain objects which transmit light at special frequencies (typically emission nebula, planetery nebula, and some galaxies) can be done through narrowband filters, which transmit light only at these very specific, narrow wavelengths, while blocking broaderband light from sources such as streetlights, house lights, and even the moon.

All images on this site have been captured at The Robservatory, located 12 miles west of Manhattan, under some of the worst light pollution on the planet.

Completed Facility


Here's a front view of The Robservatory, which rests on an elevated, octagonal deck, facing south.

Slide-Off Dome Capability







The initial configuration was for a rotating dome. However, it soon became apparent that no matter the dome position, the sky directly overhead was obstructed. In order to overcome this limitation, a rear platform was constucted. When the dome is opened, it can now be slid completely off, gliding with little effort along three tracks made of synthetic decking material. The sky overhead is now competely accessible.

Inside The Robservatory



Imaging is done with an ATK 314L+ cooled CCD camera (upgraded from 16HR shown) on a TMB92 f5.5 triplet-apo refractor with a Televue .8x focal reducer/flattener.

The guidescope is a Televue Pronto, with guiding via a StellaCam3 video camera.

A dual screen laptop is used for image capture and guiding.

The mount is a Losmandy G11 (upgraded from GM8 in photo).




Octogonal Deck


Here is a shot of the framing for the octagonal deck on which The Robservatory resides.

Pier Construction

My brother Richard helped me pour almost a ton of concrete to create a super-stable pier on which to place the telescope mount. The pier was completed on April 19, 2008. Thanks, Rich!
