  The main observatory dome will contain a 1.6 m off-axis solar telescope, the BBSO NST (New Solar Telescope). The NST has two foci, a coudé focus which sends light down to the coudé room on the second floor of the observatory building, and a Nasmyth focus on the east side of the telescope.

The small dome on the causeway north of the main dome contains a Meade equatorial mount with two telescopes, a full disk solar telescope with an H-alpha filter and an earthshine telescope. For details on the BBSO Earthshine Project see this page.

The white building at the shoreline contains a GONG telescope.


 
Full Disk Observations

Full Disk Observations

H-alpha full disk observations:

The solar full disk telescope is a 10 cm refractor with a 152 cm focal length doublet lens. It is used with a Zeiss H-alpha birefringent filter at 0.25 Å bandpass and a Pulnix 12-bit 2048 x 2048 pixel CCD camera.


 
Observations with High Spatial Resolution

Observations with High Spatial Resolution

The BBSO NST will initially be used with the following equipment:
  • An adaptive optics system for seeing correction at the coudé focus.
  • A Fabry-Pérot-based imaging magnetograph/spectrometer system for visible light at the coudé focus.
  • An infra-red imaging magnetograph/spectrometer using a combination of a Fabry-Pérot and a Lyot filter at the coudé focus.
  • A system for near real-time speckle interferometry.
The IR camera and speckle systems will also be used at the Nasmyth focus with broadband filters.
