Very Wide Field Telescope. Typically used for Wide Field RGB / Narrowband Imaging, but also carries a Photometric V filter. FITS and TIF file formats. Dark Frame calibration data is available for 60, 120, 180, 300 second exposures. Binx1 - Binx2. Recommended Maximum Exposure 300 seconds. Raw data can be found at data.itelescope.net.
- T20 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.
- This system is included for use in the Demo Upgrade Package.
- IMPORTANT NOTES: T20 is externally Guided: Please limit sub-exposure times to 300 seconds or less for best results. We recommend using the 'Dithering' imaging option on T20 to remove any column defects during your post processing.
