Observing at Copernico 182cm telescope
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.

Call results -
At the Asiago 182cm telescope a 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.
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, sending the request to proposal.oapd at inaf.it. The telescopes coordinators will arrange the approved observations.
Urgent ToO activation
For urgent ToO activation (also during the night), please follow the instructions reported in this page
Information for Local Accommodation
Starting from December 2013 all observations involving the Ekar instrumentation will be performed remotely from the Asiago-Pennar Observatory. A number of guest rooms are available at the Observatory. The observer should send an email to guest at oapd.inaf.it a few days in advance specifying the number of nights required and providing his/her personal details. Guests have to pay for the room accommodation. No restaurant facility is provided at the Observatory, except for two small kitchens 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.
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: http://www.oapd.inaf.it/meteo/index.php (MTX meteo station, positioned on the dome balcony) and at http://meteo.astro.unipd.it/weather/meteoLC.php (ARPAV probe and “Lunatico” for sky quality index). The respect of these rules is the observer's responsibility. 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.
•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 ARPAV radar image visible in the meteo pages.
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.
Starting from May 2020 a new grism will be available a multispectra VPHG grism (similar to grism-U of Dolores spectrograph at TNG. This grism will allow to get the whole optical range in one shot, with the following characteristic: wavelenght range: 1st order from 600 to 1000 nm, resolution 1.7 nm; 2nd order from 370 to 600 nm, resolution 0.9 nm.
NUMBERS TO BE CHECKED!!!
AFOSC user manual (PDF)
Starting on August 2020 the Schmidt telescope will be offered in a fully robotic mode and the telescope will observe autonomously, i.e, it will operate without human intervention.
The observation specififications will be submitted during daytime, which be considered by the telescope's robotic control system (RCS). Each night the RCS will decide for itself what to observe next, based on target priority, visibility and weather conditions. the RCS will also have a rapid-response capability where it can automatically interrupt regular observations to slew to observe transient phenomena with higher priority.
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.
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."
Policy of the observations.
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."
