We offer a selection of various telescopes, with different diameter and focal length, corresponding to different projects. For now starting with a Canon 135mm F/2 lens for wide field view of the Milky way, Astro-Physics 155 refractor with STX16803 camera and 250mm f/8 Ritchey-Chretien telescope with a ZWO Asi 1600MM Cool camera. Soon to be added are a FSQ85 Takahashi with full frame detector, Takahashi Epsilon 200mm telescope with ZWO Asi 1600MC Pro color camera, RC300mm with LISA spectrograph.

Each telescope is slightly different, but for the ones equipped with a filter wheel you can select the filter (s) you wish to use.

You have of course the possibility to choose different binning, and of course to download the corresponding calibration files (bias, darks and flats).

All images taken are checked by an automated script which checks that there are stars on the images (in rare cases with cloudy nights), that their elongation and diameter (focus+tracking+wind) is minimal, and that the field is taken on the right position in the sky (within a small given range). If you contest the images, contact us by email and we will find a solution.

We offer various options : Exposure at a given time (exoplanet transit, stellar occultation), urgent request (confirmation of supernovae, astrometry of asteroids), not urgent. Moon or no moon in the sky, you have flexibility. Price of course is lower for non urgent fields during full moon than fixed exposures during new moon.

You can choose various exposure times. There is no minimum exposure time (except that exposure times shorter than one minute are counted as one minute) and the maximum exposure time varies with each telescope
