The sidereal time is a central and by no means one of the most important parameters of NEO Planner.
The magic formula is: (Special design for NEO Planner by Father Christoph Gerhard (K74)):
Siderial time (decimal) = 6.625 + 0.06570982 * (Current date - '2019-01-01' + 1) + geographical longitude / 15 + 1.002738 * (midnight UT (decimal))
Then the conversion into hours
and minutes takes place.
The sidereal time in
combination of RA object is the criterion for reliably determining NO GO areas,
Both the sidereal time and true midnight UT is saved with every planning in the SiderialTime.txt file in the <Daily Planning> folder (see File Structure settings).

The calculated local starting
time of the planning is determined from various sources.
The start and end times of the
planning can only be reliably calculated in this way,
Display of the light conditions via a list box. At higher latitudes in the hemispheres, reduced data is shown around the time of the summer solstice and missing astronomical time.
The observation period in local time of the coming night.
The basis is the daily loading
of current astronomical data of a location from
IpGeolocation.io, which takes place automatically when NEO Planner is
started. See also: GEO
On the one hand, the entire window is saved as .jpg in the archive folder. In
addition, the content of the list display is saved both in .txt
and .csv files for further
File Structure settings).
Here you can enter the start time of the first object
manually if it should deviate from the suggested start time.
The schedule is run again with the specified start time on the left, but
significantly reduced. There is no re-determination of the objects, only a
correction of the suggested observation times.
By marking positions you can perform various actions such as C-copy, M-move, DEL-delete, G-adjust stack groups, E-ephemeris details, S-scout or M-MPC details.
Pressing 'S' on an object line takes you to the Execute Search Window.
Controlling whether the start position or center position of the object in
Execute Search is displayed in the center of the starmap picturebox can be done

Neo Planner calculates observation times in R.A. order of
currently visible comets in green according to the official publication of the MPC
In addition, all NEOCP objects in red that can be observed according to the parameter settings are displayed.
In addition, visible NEOs in blue are included that have not yet been numbered, i.e. have a provisional number.
Objects with special object classes are displayed in black.
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

The displays for arcsec / minute (s / min) and position angle (PA) refer to the observation time and come from JPL's Ephemeris Scout.
Display of the dRA and dDec proper motion of NEOCP objects to enable the proper movement in RA and Dec for direct tracking of the objects.
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 automatically by multiplying the number of groups and images / group.
The group value
basically means how many measurements for each single
object should be sent to the MPC.
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.
In the case of a group value of <4, the following applies:
Neo Planner uses the entered value from the settings at speeds of the object
greater than 3 arcsec / minute.
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
Transit of the object thru the Meridian in local time, if the buffer time is zero in the NO-GO settings.
Exception: Buffer time in the
NO GO Area settings
Computed time of observation in local time zone.
W = at the suggested time there is a real risk that the object will cross the meridian.
the object was not found on the
Scout page of the
JPL, possibly a nonexistent object.
T = The path of an object is longer than the allowed maximum length of a recording series.
M = The path of the object is fully mapped in the FoV by using the center position of the track.
Maximum path of an object from the center of the image to
the edge during a series of exposures.
The path length of an object through the FoV is calculated based on the movement
of the object in arcsec/min, its position angle,
In column Min/gr. the necessary minutes for a single
group / stack are now displayed, according to the camera
resolution and s/min. Object.
All changes are reversed and the original planning is restored..
special information about the objects such as number of previous observations,
date and observatory of the last observation,
By pressing the E key in a line of an objects, you get a
ephemeris to the minute, which can be selected up to a period of 8 hours.
The NEOCP Check function enables the planning to be updated quickly, including
the current NEOCP display. It is checked whether there are updates for
individual NEOCP objects,
