UTC Minus 7:00. Daylight savings time is observed
Minimum Target Elevation: Approx 15-20 Degrees
N 32° 54’ Decimal: 32.9 North

Elevation: 2,225 metres (7,298 ft)
Deep Field. Hybrid Missions. Typically used for Photometry and Imaging. FITS and TIF file formats. Sub-exposure times should be kept to 60, 120, 180, 300, 600, 900 seconds for optimal results. Binx1 - Binx2.
T11 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.
T11 is a DEEP field telescope and its mission can be both an excellent imaging platform or do powerful science with photometrics. T11 is a major photon hunting science machine on the iTelescope network. This instrument can deliver pin-sharp images during 300-600 second unguided exposures, reaching magnitudes as low as 21.5 without too much effort.
