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. Binx1 - Binx2. (All calibrated data uses scaled darks).
Recommended Maximum Exposure 600 seconds. Raw data can be found at data.itelescope.net.
- T20 is a great platform for wide angle imaging 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.
- IMPORTANT NOTES: T20 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.
