MILAN Sky Survey: raw images captured with a Stellina observation station
During the MILAN research project (MachIne Learning for AstroNomy), the research team uses Stellina observation stations to collect raw images of deep sky objects.
The Stellina observation station has an apochromatic ED doublet with an aperture of 80 mm and a focal length of 400 mm - focal ratio of f/5. It is equipped with a Sony IMX 178 CMOS sensor with a resolution of 6.4 million pixels (3096 x 2080 pixels). An anti-pollution filter is placed in front of the camera sensor. The station also has a fully automated alt-azimuth mount: setup, object tracking and focusing are also automatic. Stellina also has an integrated field rotator that adapts to the target.
Thus, the research team built a dataset that faithfully represents what can be obtained during classical Electronically Assisted Astronomy sessions in the Luxembourg Greater Region:
- targets: representative set of deep sky objects from the Messier / NGC / IC / Barnard / Sharpless catalogs during the period.
- type of targets: nebulae, planetary nebula, galaxies, globular clusters, open clusters
- for each observation session: sub-frames of 10 seconds exposure time and total cumulative duration of ~15/30 minutes (depending on the target) -- bad sub-frames were not filtered.
The dataset is composed of ZIP files -- and each zip file contains raw images in FITS format (Flexible Image Transport System): data comes directly from the Sony IMX178 sensor of the Stellina observation station (no debayerisation and no post processing).
