A first data release (DR0.1) of the entire surveyed region, including Hα and continuum data, was published in October 2024.
More results from selected regions can be found in the “Images” section. Any of these images show faint nebulae that haven't been cataloged before (which does not mean they are unknown). An attempt to list these objects can be found on the Uncataloged objects page.
A first data release with a complete set of Hα and low-resolution continuum images (instruments 1-4, see below) is scheduled for the end of 2024.
Below are two tables. The first one describes the different instruments, and the second one lists how many of the instruments from the first table are active in which period.
Instrument index | Emission line, Bandwidth / Passband / Filter | Field of view | Aperture | Resolution | Comment |
---|---|---|---|---|---|
1 | 656.3 nm (Hα), 3.5nm | 7.6° × 5.8° | 5 cm | 9″ (FWHM) | Panasonic MN34230 sensor, f=135 mm lens |
2 | Bayer CFA + Light pollution filter | 15.5° × 10.3° | 7 cm | 17″ (FWHM) | DSLR camera, f=135 mm lens |
3 | 656.3 nm (Hα), 3.5 nm | 7.6° × 5.8° | 6 cm | 9″ (FWHM) | Panasonic MN34230 sensor, f=135 mm lens |
4 | 656.3 nm (Hα), 35 nm | 7.6° × 5.8° | 5 cm | 9″ (FWHM) | Panasonic MN34230 sensor, f=135 mm lens. Used for exact continuum measurement (wide passband centered to emission line). |
5a | 410 nm to 550 nm (SDSS G') | 6.8° × 4.5° | 10 cm | 7″ (FWHM) | Sony IMX455 sensor, f=300 mm lens |

5c | 695 nm to 845 nm (SDSS I') | 6.8° × 4.5° | 10 cm | 7″ (FWHM) | Sony IMX455 sensor, f=300 mm lens |
6a | 505.7 nm ([OIII]), 4 nm | 10° × 6.8° | 6 cm | 10″ (FWHM) | Sony IMX571 sensor, f=135 mm lens |
6b | 671.7 nm and 673.0 nm ([SII]), 4 nm | 10° × 6.8° | 6 cm | 10″ (FWHM) | Sony IMX571 sensor, f=135 mm lens |

Interestingly, the arc has been detected in the preview images of the first clear night after the camera array reached its full configuration. Furthermore, it is the first image that contains data from all three emission lines. So, this detection can be seen as the first light of the full array configuration.
