Operational Notes

Wide - Medium Deep Field Telescope. Hybrid Science/Imaging Platorm. Typically used for RVB / Narrowband Imaging, but also carries Photometric V and I filters. FITS and TIF file formats. Dark Frame calibration data is available for  60, 120, 180, 300, 600  second exposures. Binx1 - Binx2.  Raw data can be found at

  • Recommended Maximum Exposure 600 seconds.
  • T16 is a wonderful research grade APO refractor. It can deliver razor sharp, wide images.
  • Please be aware that it is common for some CCD chips to display column defects. Follow this link for more information.
  • IMPORTANT NOTES: T16 is Externally Guided: Please limit sub-exposure times to 300 seconds or less for best results.
