AAVSOnet

The AAVSO Robotic Telescope Network

SRO50 W28 W30 BSM APASS OC61

The AAVSO now maintains a network of remote, robotically controlled, and automatically queued telescopes for the use of its members. Five telescopes, all located in the southwestern United States, are currently active and taking data right now.

Chi PerThe telescopes are all automatically scheduled using ACP, with image acquisition and telescope control by Maxim-DL. Time on the telescopes is shared between AAVSO key projects (primarily surveys and field calibrations) and AAVSO member programs. Time on AAVSOnet telescopes is awarded on a nominally competitive basis, although the systems may be used by members for any reasonable purpose if time is available.

To request time on these telescopes, you must be a current member of the AAVSO in good standing, or have the approval of the AAVSO Time Allocation Committee. To submit a proposal to use these telescopes, please complete the Proposal Submission Form. For a list of previous observing runs, click here.

SRO50

SRO50 is a 50-cm, f/4 telescope located at the Sonoita Research Observatory near Sonoita, Arizona (UT-7) 

  • Camera: STL-6303E

 

 

 

W28

W28 (Wright-28) is a 28-cm Celestron C-11 located at the Astrokolkhoz telescope facility near Cloudcroft, New Mexico (UT-7). This telescope was donated to the AAVSO by the late Paul Wright.

  • Camera: SBIG ST7
  • FOV: 14' x 9'
  • Pixel scale: 1.08 arcsec/pixel
  • Filters: 10-position filter wheel, with Johnson-Cousins BVRcIc, clear filter, Sloan gr, H-alpha (line), H-alpha (continuum, R645), and [SII] (line)

W30

W30 (Wright-30) is a 30-cm Meade LX200 also located at the Astrokolkhoz telescope facility near Cloudcroft, New Mexico (UT-7). This telescope was donated to the AAVSO by the late Paul Wright.

  • Camera: SBIG ST9
  • FOV: 16' x 16'
  • Pixel scale: 1.9 arcsec/pixel
  • Filters: 5-position filter wheel, with Johnson-Cousins BVRcIc and clear filters

BSM

BSM, the AAVSO Bright Star Monitor is a 6-cm wide-field telescope located at the Astrokolkhoz telescope facility near Cloudcroft, New Mexico (UT-7). It is intended for photometry and monitoring of bright stars (V < 9.0).

  • Camera: SBIG ST8XME
  • FOV: 127' x 84'
  • Pixel scale: 4.97 arcsec/pixel
  • Filters: 5-position filter wheel, with Johnson-Cousins BVRcIc and clear filters

APASS

APASS, the AAVSO Photometric All-Sky Survey is made of two 20-cm telescopes co-mounted on the same platform, and capable of monitoring the same field in two filters simultaneously. It is located at the Dark Ridge Observatory near Weed, New Mexico (UT-7).

  • Camera: Apogee Alta U16M
  • FOV: 174' x 174'
  • Pixel scale: 2.6 arcsec/pixel
  • Filters: Johnson BV, clear, and Sloan ugriz

OC61


OC61
(coming soon), an Optical Craftsman 0.61-meter telescope located at the Mount John University Observatory of the University of Canterbury, New Zealand (UT+12).  It will be the first of the southern hemisphere telescopes in AAVSOnet, providing global sky coverage for the AAVSO community!

  • Camera: Finger Lakes PL09000
  • Pixel scale: 0.3 arcsec/pixel
  • FOV: 16' x 16'
  • Filters: Johnson BV, clear, and Sloan ri

 

Future Additions

The following telescopes will be added to AAVSOnet in the coming months. Stay tuned to be notified when they are online and operational!

Cohen/Menke Observatory

At the AAVSO HQ, a 12-inch LX200 telescope (Cohen30) will be installed. This telescope will have an ST8XME camera and filter wheel, with a pixel scale of 0.62arcsec/pix and a field of view of 15.7x10.5arcmin. Boston is not well known as a great observing site, so we expect less than 100 nights per year to be useable, and with the bright urban light dome, this facility will not go as faint as our other sites. The advantages of the Cohen30 will be as a testbed for new instrumentation, for circumpolar objects, and to provide observations during the Southwestern July/August monsoon (when weather is best in the Boston area).
