This page and related links give information on astronomical observations at the 1.82m telescope, located at Cima Ekar-Asiago(Italy).

Observing time is allocated purely on the basis of scientific merit of the applications. Large project proposal call is opened every two years, while small project proposals can be send to proposal.oapd at inaf.it at any moment. See templates below.


Time allocation

Service mode

At the Asiago 182cm telescope a limited number of programs require observations in Service Mode. These observations will be performed by staff observers during dedicated nights. For request observing time fill this form (Short proposal)

Target of opportunity

At the Asiago 182cm telescope Target of Opportunity (ToO) programmes may be executed during the nights allocated for other projects. In general a ToO observation will take less than 1 hour to be performed. No compensation for time lost is given to the observer. Observers are invited to collaborate where possible in applications for ToO observations.

ToO trigger must be sent by the PI of already approved Large proposals to the night observers and, in CC, to proposal.oapd at inaf.it .

For all others ToO triggers, the proposers must follow the procedure for the activation of Small project proposals. The telescopes coordinators will arrange the approved observations.

Information for Local Accommodation

Observations involving the Ekar instrumentation can be performed remotely from the Asiago-Pennar Observatory. A couple of guest rooms (n. 3 and n. 4) are always reserved at the Observatory for hosting two observers. No restaurant facility is provided at the Observatory, except for a small kitchen located in the same building as the guest rooms. In practice, accommodation in town is a good option, difficult to book only in July, August, at Christmas and in February.

Observing constraints

A number of distributed probes record the temperature, humidity inside and outside the dome, the wind speed, the sky overcast, rain rate, etc. These data are archived by the weather monitoring system and are visible for the observer in the Meteo web page: https://web.oapd.inaf.it/meteo-ekar/meteo.php. The software that controls the remote observing will, in any case, warn the observer on the weather conditions and will interrupt the observations if no action is taken by the observer. All actions taken during the night, together with the weather conditions, will be stored in a log file for future inspection. The respect of the safety rules is the observer's responsibility.

  • Close or keep the dome closed when the relative humidity exceeds 92%

  • Close the dome if the wind speed reaches, even if temporary (with a single gust), 10 m/s

  • Close the dome when the sky quality index reaches values higher than -10 (overcast)

  • Close the dome immediately if rain drops are recorded

However to avoid severe damage of the mirror coating and electronics the dome must be closed well in advance before the rain (snow) drops are recorded. Observers may check the rainfall status over the Asiago area in the radar images visible in the meteo web page.

Night report.

Please note that all observers at the end of each session of night work are asked to fill the night report indicating clearly where problems were found during observations in order to be able to solve the problems and to allow the observation for the next night. You can find the page to be filled " here."

AFOSC standard set-up and calibration

In order to minimise the technical interventions and to have a more stable instrument we have foreseen the following basic AFOSC set-up:

Aperture wheel: slits 1.26”; 1.69”, 2.50” and 4.22”

Filter wheel: u,B,V,g,r,i,z

Grism wheel: gr4, VPH6, VPH7

For this basic set-up the telescope operating team secures, every time AFOSC is mounted, the corresponding calibrations. They are taken with the CCD binned 2x2 and read-out modes of 50Kzx2 Hisens for spectroscopy and 1MHzx2 Hisens for imaging. Ne and Hg-Cd arcs are also secured for the different slits/grism combinations. If observers need a different AFOSC set-up they must communicate it to the telescope operating team well before (at least one week before) the beginning of the observations. In this case, it will be responsibility of the observer to take the appropriate calibrations.

Schmidt telescope

Starting on August 2020 the Schmidt telescope is offered in a fully robotic mode and the telescope operate without human intervention.

The observing blocks (OB) are submitted during daytime by the PIs of Large Proposals and their collaborators.

The Robotic System have a rapid-response capability and it can automatically interrupt regular observations to slew to observe transient phenomena with higher priority.

The Asiago Adaptive Optics Facility (ADONI lab)

The AO testing facility at the Coudè focus of the Copernico Telescope is available for on-sky experimentation. It is a permanent laboratory with the aim of hosting visiting multi-purpose instrumentation that may be directly tested on sky.

Data Policy for the Cima Ekar Observatory

The data obtained with the telescope of Cima Ekar (Asiago) have a proprietary period of 1 year since the date of the observations and are available from the Archive (Archive link-ato a http://ia2.oats.inaf.it/archives/asiago), and, for the first ~3 months, also in a mirror/site in Asiago/EKAR (con mirrow/site link-ato a http://hactar.oapd.inaf.it/aao/faces/search.xhtml?dswid=-9999). After the proprietary period all the data are released and become available from the Archive


It is mandatory that publications based on Ekar-Asiago proprietary or archive observations shall have in a footnote on the first page of the article or in the Acknowledgments section the following citation: "based on observations collected at Copernico (or/and Schmidt) telescope(s) (Asiago, Italy) of the INAF - Osservatorio Astronomico di Padova."
