Prospect for UV observations from the Moon. III. Assembly and ground calibration of Lunar Ultraviolet Cosmic Imager (LUCI)
The Lunar Ultraviolet Cosmic Imager (LUCI) is a near-ultraviolet (NUV) telescope with all-spherical mirrors, designed and built to fly as a scientific payload on a lunar mission with Team Indus—the original In...

All-sky ultraviolet surveys: the needs and the means
This is a crucial time in the history of astronomy with major all-sky surveying work being carried out in all spectral bands, as well as in astrometry. The results of this activity are advancing all fields of ...

Wide-field ultraviolet imager for astronomical transient studies
Though the ultraviolet (UV) domain plays a vital role in the studies of astronomical transient events, the UV time-domain sky remains largely unexplored. We have designed a wide-field UV imager that can be flo...

Prospect for UV observations from the Moon. II. Instrumental design of an ultraviolet imager LUCI
We present a design for a near-ultraviolet (NUV) imaging instrument which may be flown on a range of available platforms, including high-altitude balloons, nanosatellites, or space missions. Although all curre...

The Jay Baum Rich telescope: a Centurion 28 at the Wise Observatory
We describe the third telescope of the Wise Observatory, a 0.70-m Centurion 28 (C28IL) installed in 2013 and named the Jay Baum Rich telescope to enhance significantly the wide-field imaging possibilities of t...

Small observatories for the UV
We describe concepts for small space telescopes that are able to provide significant UV science and can be realized with small (but realistic) budgets. The concepts are based on nano-satellites carrying small ...

An optical-UV survey of the North Celestial Cap
We present preliminary results of an optical-UV survey of the North Celestial Cap (NCCS) based on ∼5% areal coverage. The NCCS will provide good photometric and astrometric data for the North Celestial Cap reg...

Exotic UV astronomy
After considering a number of historical but somewhat “forgotten” UV astronomy experiments, I discuss a number of ways of non-conventional astronomy in the ultraviolet that, on first considerations, could be v...
