Notes to the given image data

Date: shown in the german convention: day.month.year, corresponding to exposure start in UT
Time: given in UT (Universal Time) at start of first exposure. UT corresponds to Greenwich Mean Time (longitude 0).
Central European Time CET = UT + 1:00
(UT = UTC +- 1s)
Exposure: Length of total integration time. It is given for each used filter, but each total integration time may consist of many exposures added together.
Field of View: The shown field of view in the image in degrees (o) or arc minutes ('). 1o = 60'. X axis versus Y axis. This field is in most cases smaller than the total exposed field on the detector.
Receiver or
Emulsion:
The used CCD camera system with number of pixels or the conventional film material.
Filter: Most CCD images are taken through a Johnson-Cousins BVRI filter set (see WWFPP filter page)
Instrument,
Optics:
The telescope aperture and eventually the focal length. For small photo optics the focal length f and the used focal ratio d/f is given as usual.
Observatory,
Place:
evident
Observer: evident
