# Multi Object Spectrograph of the Fireball-II Balloon Experiment

## TL;DR

The paper presents the design and implementation of a multi-object spectrograph for the Fireball-II balloon experiment, aimed at studying faint ultraviolet emissions from galaxies in space.

## Contribution

It introduces a novel MOS system based on two identical reflective Schmidt telescopes with an active optics grating for balloon-borne ultraviolet observations.

## Key findings

- Successful development of a space-optimized MOS system
- Enhanced capability to observe faint ultraviolet galaxy emissions
- Potential for improved space-based spectroscopic studies

## Abstract

Fireball-II is a NASA/CNES balloon-borne telescope and MOS to study faint diffuse emissions of galaxies in the space ultraviolet. The MOS is based on two identical reflective Schmidt systems sharing an plane-aspherized grating obtained by active optics methods.
