Operational Notes

Very Wide Field Telescope. Typically used for Wide Field RGB / Narrowband Imaging.
FITS and TIF file formats. Dark Frame calibration data is available for 900 second exposures. (All calibrated data uses scaled darks). Binx1 - Binx2. Recommended Maximum Exposure 600 seconds. Raw data can be found at

  • T14 is a great platform for wide angle imaging and can also do valuable science with its photometric V filter. This little Takahashi FSQ gets a lot of use from science users scanning for asteroids and working on variable stars, and nothing can match its very wide field portraits and its performance on the sky's larger extended objects such as large nebula, clusters, bright comets and even catching fast moving Near Earth Objects.
  • Please be aware that it is common for some CCD chips to display column defects. Follow this link for more information.

  • IMPORTANT NOTES: T14 is unguided. Please limit sub-exposure times to 600 seconds or less for best results. We recommend using the 'Dithering' imaging option on T20 to remove any column defects during your post processing.
