Don't waste time planning the night session and focus on the evaluation...

A warm welcome to all friends of comets and minor planets!  

We are living on a beautyful planet, surrounded in space from its large and small brothers and sisters since unimaginable times.
This web is an independant and ad-free approach to the grand show in our neighborhood in space 
with equipment geared towards tracking nearby earth cruisers.

The collaboration of amateurs in the follow-up observation of Near Earth Objects and comets is important
and I am delighted to be part of this global team of very special profs and amateurs.
For me as an amateur, participating in the measurement of near-earth bodies is definitely inspiring for my demanding hobby.

And I call on every amateur not only to photograph the beloved deep-sky objects and planets, but also to actively participate
in the observation and measurement of Near Earth Objects.
Measurements of NEO can be carried out independently of the moon phases and enrich the hobby immensely.


Over 10,000 individual measurements of more than 1000 Near Earth Objects on K87 Dettelbach Vineyard Observatory since 2017.

The following image shows the Execute Search Window triggered by the "S" function in the Revise Planning Window.

Illustration of the path of an object in NEO Planner: Leave nothing to chance anymore, but check the paths of each object before the session and adjust the recording times if necessary.

NEO Planner is for free, code-protected and works for all IAU stations worldwide.   

Current users: 104, 958, B50, B72, C95, E89, G04, G19, K19, K35, K55, K74, K83, K87, L40, L63, L65, L81, M18, M26, M45, M49, U52, X93
                          (Brazil, Germany,  France, Italy, Namibia, New Zealand, Romania, U.S.A.)

Amateur or professional observers are welcome to use NEO Planner.  Current version: V4.5.0  (May 24 2023)   

NEO Planner is able to calculate the exposure times, the required number of exposures and the positions of currently observable comets, NEO and NEOCP objects
on the basis of MPC, JPL Horizons and JPL Scout data and and bring them in a time sequence for each location and for any equipment.

In addition, NEO Planner automatically monitors the NEOCP and provides the user with important current changes, both visually and, if desired, acoustically.
NEO Planner can work with both Astrometrica and Tycho
and provides scripts for automatic night session control for both TheSky X (Orchestrate) and N.I.N.A (XML + JSON).

If desired, the planning and ephemeris can be uploaded to a website to be followed from any location and browser.
An internal sniping tool enables timer controlled hard copies of the screen and the viewing of the night sessions via the website.

The Integration of NEO Planner into the ASCOM based Nighttime Imaging 'N' Astronomy program N.I.N.A. by Stefan Berg about XML and JSON formats
enables the fully automatic observation of the planning proposal, even with German mounts.

NEO Planner supports up to five cameras and devices. The Execute Search Window supports searching for new objects with a mosaic display of the star background.
Any deep sky object can also be displayed and selected in this window.
The calculated positions of a mosaic are sent to N.I.N.A. delivered via a sophisticated XML and JSON interface, enabling an automatic search for near-Earth objects.
The Execute Search Window can also be used via the "S" function in the Revise Window, which shows the path of the selected planning object together with the star background.
In addition, the asteroid classes Mars Crosser, Jupiter Trojan, Centaur, TransNeptunian Object and Hyperbolic Asteroid can be integrated into the Execute Planning process.

And many features more...

Customizable graphical platform of NEO and comet discoveries since 2020:

Presented here are the NEO discoveries of our user Christophe Demeautis from the K19 PASTIS observatory, Banon in France from 2021 to 2023.
The green North - South axis represents the sidereal time at the time of discovery. The East - West lines represent the declination.

Congratulations to Christophe Demeautis from K19 PASTIS Observatory, Banon, France on discovering
  2021 YQ, 2022 BU1 2022 HE3, 2022 NF1, 2022 SW3 2022 SE6 2022 TV2 2022 TW2, 2023 CN3 and 2023 HC, on his station !!! 
He also discovered the NEOs 2022 SK9 and 2022 SX7 together with the team from 033 Karl Schwarzschild Observatory, Tautenburg.  

My auto-guiding telescope (LX600) and the cmos-camera (QHY600L) are fully automatic controlled by the programs Orchestrate and TheSky X Pro of Software Bisque over the night session.
The focuser works temperature controlled and is focused one time in the evening on a star in 50 altitude. For users automatic recordings are also available with a N.I.N.A interface.

Both the following template and the script for Orchestrate and the XML- and JSON scripts for N.I.N.A. are generated by self-written  programs on .NET platform.

The preparation time for a night session usually takes about 15 - 30 minutes. High Moon phases are requiring more time.

Examples of interfaces: Script for Orchestrate  and Template, XML and JSON for N.I.N.A.          

Example of a Program from February, 20 2023 for K87:

Copyright: The data comes from official access to web services from MPC, JPL, NASA and ESA, whose origins are the tireless measurements of dozens of professional and amateur observatories around the world

All parameters of the template are calculated for my equipment on location K87 and based on expected SQM results from Mag/SqArcsec 20 and weaker within the observation slot.
The Vmag average is the average of the last 10 observations of the objects taken from the MPC observation site.

Some events of the last years:   September, 21 2020 - first night half

Around midnight a bright shooting star of the Southern Piscids crossed Andromeda and Lacerta
and ended its brief light show with a small explosion in the lizard's head... and is this meteor connected with some NEOs? - may be.

Southern Piscid

Elevation: 267m, Processing: Adobe Lightroom and Photoshop. No stiffeners, airplanes or satellites on the image.

The red cross marks the radiant of the Southern Piscids meteor shower, annual maximum: September 20th. Mars is in the lower left.

In this paper by P. B. Babadzhanov - I. P. Williams - G. I. Kokhirova from 2007, the connection between the September Piscids and some Near Earth objects is discussed.

Moon, Mars, Venus, Jupiter and Saturn came together this morning with the beautiful comet C/2020 F3 NEOWISE.

A moment to pause and think about the beauty and size of our universe. This morning made my face smile.


I left my telescope with its automatic scanning of the sky and drove a few kilometers to the highest elevation nearby.
There one of the best moments of nighttime observations awaited me.

There are two dots westward the central condensation. The comet tail is looking more and more like a cigar.

Here you find a light curve of the comet on CometasObs showing a decrease of the central magnitude since March, 28 2020
