Photometric Standard stars
A catalogue with selected photometric standard star fields is
available from the
TCS (alphot.cat). These fields have three
or more "well" observed stars from
Landolt, A. 2009 AJ 137 4186.
The full catalogue (exluding the TPhe-field) ia also
available (landolt_aj_137.cat) and the old
Landolt, A. 1992 AJ 104 340 version as
landolt_aj_104.cat)
The easiest way to access these stars are using guide-object TCS-command e.g.
tcs.guide-object A_F11 from the sequencer terminal or
goto-object A_F11 from the TCS and wait until the telescope is autoguiding.
The suggested integration times are not yet included for every field.

candidate standard stars from SDSS stripe 82:
|Dec|<1.266 deg and RA in the range 20h 34m to 4h 00m; about 300 sq.deg.
Stetson Photometric Standard Fields
229 fields, with BVRI photometry, some southern fields;
see also

A catalogue of "Stetson" standard stars with declination > -40deg is available from the
TCS (stetson.cat).
Stetson fields in the
TCS-catalogue have a prefix "S_" e.g. "S_Ru149".
Selected fields BVRI photometry: NGC2419 (approximate centre RA=07h38m10s dec=+39:52:56),
