< Previous Telescope | Next Telescope >
Location Information
Observatory: Utah Desert Remote Observatory at Great Basin Desert, Beryl Junction, Utah, USA
MPC: U94
Telescope: 0.43-m f/6.8 reflector + CCD
Timezone: UTC Minus 7:00. Daylight savings time is observed
Minimum Target Elevation: 15º all azimuths except noted. 23º elevation for azimuths 50-130º.
N 37° 44’ 16" Decimal: 37.7378 North
W 113° 41’ 51" Decimal: -113.6975 West
Elevation: 1,570 meters / 5150 ft
Operational Notes
Deep Field. Hybrid Missions. Typically used for Photometry and Imaging. FITS and TIF file formats. Dark Frame calibration data is scaled from 600 second Dark Frame exposures. Binx1 - Binx2. Raw data can be found at data.itelescope.net.
- Recommended Maximum Exposure 600 seconds.
- 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.
- T19 is a 'Full House' telescope system. It can Image deeply and do powerful science.

Transformation Coefficients
VPHOT system –
Tub= 1.035; standard deviation= .010
Tbv= 0.974 ; standard deviation= .012
Tvr= 1.077 ; standard deviation= .011
Tri= 1.009 ; standard deviation= .018
Tv= 0.012 ; standard deviation= .006
Tr= -0.048; standard deviation= .015
Ti= -0.063; standard deviation= .004
Tb= -0.009; standard deviation= .014
These use the following definitions (lower case are instrument magnitudes; upper case are reference magnitudes of NGC7790 from Arne Henden’s standard field available at http://binaries.boulder.swri.edu/fields/ngc7790.html)
Tv= slope of (V-v)/(B-V)
Tr= slope of (R-r)/(V-R)
Ti= slope of (I-i)/(R-I)
Tb= slope(B-b)/(U-B)
