With comets y/n:

Select here whether you want to include comets in the planning or not.

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 CometasObs.
The reason for including the CometasObs observations lies in the sometimes considerable delay of the MPC in the publication of the last observations.

More information on the inclusion of comets in the planning process can be found here.

NEO from year:

NEO with provisional designations are always included in the planning. Enter the starting year of designations of objects not yet numbered.

These objects have not yet been finally numbered and require further follow-up observations. Recently discovered NEO, in particular, require further observation to improve their orbital elements.
The uncertainty factor U plays a special role in the orbital elements. Objects with a U factor of 3 or greater cannot be safely recovered in coming orbits. U = 0 is the best value.
It is therefore a special and valuable task for amateurs to help improve the orbital elements of the NEO.

NEO to year:

Enter the final year of designations of objects not yet numbered.

With numbered asteroids y/n:

Numbered objects are not in the foreground of the observation priorities. However, there may be reasons for observing objects whose orbit is very well known.
In the case of numbered NEOs such as 99944 Apophis or other asteroids that are passing very close to Earth, there may well be an interest in tracking such NEOs.
In particular, to make meaningful videos for presentation purposes or for other reasons, it can make perfect sense also to follow such objects.
In addition, around the full moon there is a good opportunity for diligent observers to include numbered NEOs in the list to compensate for the lack of other objects.

That is why NEO Planner offers the option of including numbered objects in the selection.

In order to organize the performance of the planning process and the access to various servers within a reasonable framework, numbered objects can only be included to a limited extent.
This restriction is implemented by including the parameter 'days since last orbit update' from the 'Object selection' area of the settings.
The parameter controls until how many days in the past the last updates of the MPC for new orbital elements happend and include those in the planning.

Example: If you enter 10 as the parameter value, only those objects will be included for which a new orbit has been published since the last 10 days.
Around full moon nights I personally increase my value to 99 and include numbered asteroids in my selection. Later I switch it back to 10 and deselect numbered asteroids..

With own object list y/n:

Depending on the interest, the observer can create his own object list with any asteroids, which can be included in the planning selection area.
Application examples are the self-discovered numbered asteroids, which mostly come from the main belt, or discovered objects that are not yet numbered.

With the help of this function, a previously popular follow-up list of your own objects is no longer necessary.
T
hese objects are included in the planning process and taken into account in the final list, if the selection was successful according to the settings parameters.
