J'ai testé également le Télescope N° 11 un 500
Location
Observatory: Mayhill, New Mexico (New Mexico Skies) - MPC H06
(TEL T11 0.50-m f/6.8 astrograph + CCD + f/4.5 focal reducer)
UTC Minus 7:00. Daylight savings time is observed
Minimum Target Elevation: Approx 15-20 Degrees
N 32° 54’ Decimal: 32.9 North
W 105° 31’ Decimal: 105.5 West
Elevation: 2,225 metres (7,298 ft)
Recommended Maximum Exposure 600 seconds.
T11 is fitted with a 0.66 Focal reducer.
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.
