Operational Notes
Medium Deep Field. Hybrid Imaging/Science Missions. FITS and TIF file formats. Dark Frame calibration data is available for 60, 120, 180, 300, 600, 900 second exposures. Bin 1 and Bin 2 Raw data can be found at data.itelescope.net.
- Recommended Maximum Exposure 600 seconds.
- T18 is an excellent Imager but also has a research grade photometric V and Ic filter added.
- This system is included for use in the Demo Upgrade Package.
- IMPORTANT NOTES: T18 is Externally Guided: Please limit sub-exposure times to 300 seconds or less for best results.
