Basic information about the marathon:
Competitors gather from 6:30 p.m. in the meadow east of the Višnjan Observatory in Tičan. The competition starts at 7:30 p.m. and lasts until 5:30 a.m., or according to the judge’s decision on temporary interruption and/or earlier completion in the event of a change in weather conditions. Each competition team consists of two competitors: the main competitor and an assistant who report the found objects to the judge.

What to bring and how to prepare:
The competition will take place on a grassy meadow. Please note that the terrain may be wet, so we recommend taking with you a working PVC film on which the equipment and observer will be placed. The terrain is quite open and it is necessary to follow the wind forecast. In the event of a strong wind, please take care about wind protection for yourself and the telescope. It is not allowed to park your car on the grass where the competition will take place! Please prepare your equipment in advance and leave your car on the parking lot! In case of need, local organization committee will help you bring your equipment on the location. Please do not hesitate to contact the organisers on +385 91 449 1788 or via email:

It would be desirable to study the available literature – manuals are on the Internet: The Observing Guide to the Messier Marathon A Handbook, Deep Sky Companions The Messier Objects, Deep-Sky Companions Hidden Treasures

All participants will be accommodated in multi-bed rooms, in the dormitory building in Višnjan. Bed sheets and blankets will be provided.
