NightMon-astro

NightMon-astro is designed to monitor the night sky brightness over the upware hemisphere. It uses a raspberry pi 4b and a HQ raspberry cam with a fisheye lens. There is also a RTC chip to keep the time in case of powering off the system.

In output, NightMon-astro produce 6 calibrated maps of the sky brightness in the R, V and B Johnson astronomical bands with and without the stars. When a list of azimuth and elevation is provided, the NightMon-astro will extract the night sky brightness at the given angles from the starless images.

Optical considerations

The lens use is the .... We keep the IR filter on the lens along with the one installed on the camera body. We are using the Arducam 180 Degree Fisheye 1/2.3" M12 Lens with Lens Adapter for Raspberry Pi High Quality Camera (SKU: LN031). You can get that lens from uctronics.com .

3D printed enclosure

We designed a small enclosure to host the NightMon-astro. You can download the STL files to proceed with their 3D pring.
