Neo Planner calculates observation times in R.A. order of
currently visible comets according to the official publication of the MPC and
additionally the most recently observed comets from
In addition, all NEOCP objects that can be observed according to the parameter settings are displayed.
In addition, visible NEOs are included that have not yet been numbered, i.e. have a provisional number.
observation times of the objects are first calculated based on their meridian
passage and thus the sequence is determined.
The altitude corresponds to the height of the object above the horizon at the time of the displayed observation time.
The displays of the moon phase, the distance between the moon and the object in degrees and altitude of the Moon relate to the observation time and come from the Ephemeris Scout from JPL.

NEOCP objects: Vmag of the Scout Query
The displays for arcsec / minute (s / min) and position angle (PA) refer to the observation time and come from JPL's Ephemeris Scout.
A comprehensive description of the calculation of the exposure time can be found on the settings parameter for the sky background on the page for CCD parameters.
The number of images is calculated by multiplying Number groups (No. groups) and images / group.
A comprehensive description of the number of groups can be found on the settings parameter for the sky background on the page for CCD parameters.
Neo Planner uses the entered value from the settings at speeds of the object
greater than 3 arcsec / minute.
The value of the group can be overwritten manually and adjusted according to your own taste. To do this, press the G key on the position line.
A comprehensive description of the calculation of the images per group can be found on the settings parameter for the sky background on the page for CCD parameters
W = at the suggested time there is a real risk that the object will cross the meridian.
F = the object was not found on the Scout page of the JPL, possibly a nonexistent object.
