Abstract. Camera lenses are increasingly used in wide-field astronomical surveys due to their high performance, wide field-of-view (FOV) unreachable from traditional telescope optics, and modest cost. The machining and assembly tolerances for commercially available optical systems cause a slight misalignment (tilt) between the lens and CCD, resulting in point spread function (PSF) degradation. We have built an automated alignment system (Robotilters) to solve this challenge, optimizing four… Expand
Orbital Foregrounds for Ultra-short Duration Transients
Reflections from objects in Earth orbit can produce sub-second, star-like optical flashes similar to astrophysical transients. Reflections have historically caused false alarms for transient surveys,Expand
Adaptive inertia weight particle swarm algorithm for optimized hyperspectral image enhancement
The selection of representative bands corresponding to natural-color appearance, the image enhancement for visualization, and the investigation of the suitable cost function for hyperspectral image visualization are proposed. Expand


Evryscope Robotilter automated camera / ccd alignment system
We have deployed a new class of telescope, the Evryscope, which opens a new parameter space in optical astronomy - the ability to detect short time scale events across the entire sky simultaneously.Expand
LSST Telescope Alignment Plan Based on Nodal Aberration Theory
The optical alignment of the Large Synoptic Survey Telescope (LSST) is potentially challenging, due to its fast three-mirror optical design and its large 3.5° field of view (FOV). It is highlyExpand
PROMPT: Panchromatic robotic optical monitoring and polarimetry telescopes
Funded by $1.2M in grants and donations, we are now building PROMPT at CTIO. When completed in late 2005, PROMPT will consist of six 0.41-meter diameter Ritchey-Chretien telescopes on rapidly slewingExpand
Wide‐Field Millimagnitude Photometry with the HAT: A Tool for Extrasolar Planet Detection
ABSTRACT We discuss the system requirements for obtaining millimagnitude photometric precision over a wide field using small‐aperture, short focal length telescope systems such as those beingExpand
Aligning the ZTF science focal plane using stellar images
The Zwicky Transient Facility (ZTF) is a next-generation, optical, synoptic survey that leverages the success of the Palomar Transient Factory (PTF). ZTF has a large science focal plane (SFP) thatExpand
The Pan-STARRS wide-field optical/NIR imaging survey
Pan-STARRS is a highly cost-effective, modular and scalable approach to wide-field optical/NIR imaging. It uses 1.8m telescopes with very large (7 square degree) field of view and revolutionary1.4Expand
The Fly's Eye Camera System -- an instrument design for large \'etendue time-domain survey
The design concepts of the Fly's Eye Camera System, a proposed high resolution all-sky monitoring device which intends to perform high cadence time domain astronomy in multiple optical passbands while still accomplish a highetendue, are summarized. Expand

Evryscope science: exploring the potential of all-sky gigapixel-scale telescopes
Low-cost mass-produced sensors and optics have recently made it feasible to build telescope arrays which observe the entire accessible sky simultaneously. In this article, we discuss the scientificExpand
PSF modelling for very wide-field CCD astronomy
One of the possible approaches to detecting optical counterparts of GRBs requires monitoring large parts of the sky. This idea has gained some instrumental support in recent years, such as with theExpand
