Operational Notes


Deep Field. Hybrid Missions. Typically used for Photometry and Imaging. 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 data.itelescope.net.


  • Recommended Maximum Exposure 300 seconds.
  • T30 is fitted with a 0.66 Focal reducer.
  • The Planewave Ascension 200HR mount is so accurate whilst tracking that iTelescope Admin have disabled active guidance, with a corresponding decrease in session setup time when imaging.
  • Note: T30 is fitted with a very sensitive  Non Anti Blooming Gate (NABG) CCD. Beware of long exposures on moderate to bright stars or targets and use a bracket of short exposures or use software to repair any blooming artifacts.
