We use a Lucky Imaging system to obtain I -band images with much improved angular resolution on a 2.5 m telescope. We present results from a 10-night assessment campaign on the 2.56 m Nordic Optical Telescope and quantify the performance of our system in seeings better than 1.0 '' . In good seeing we have acquired near diffraction-limited images; in poorer seeing the angular resolution has been routinely improved by factors of 2.5–4. The system can use guide stars as faint as $I=16$ with full… Expand
High-efficiency lucky imaging
Lucky imaging is now an established observing procedure that delivers near-diffraction-limited images in the visible on ground-based telescopes up to similar to 2.5 m in diameter. Combined withExpand
Lucky imaging: beyond binary stars
Lucky imaging is a technique for high resolution astronomical imaging at visible wavelengths, utilising medium sized ground based telescopes in the 2--4m class. The technique uses high speed, lowExpand
AOLI: Adaptive Optics Lucky Imager: diffraction limited imaging in the visible on large ground-based telescopes
The highest resolution images ever taken in the visible were obtained by combining Lucky Imaging and low order adaptive optics. This paper describes a new instrument to be deployed on the WHT 4.2mExpand
High-resolution optical imaging of the core of the globular cluster M15 with FastCam
We present high-resolution I-band imaging of the core of the globular cluster M15 obtained at the 2.5-m Nordic Optical Telescope with FastCam, a low readout noise L3CCD-based instrument. ShortExpand
High-Resolution Imaging at the SOAR Telescope
Bright single and binary stars were observed at the 4.1 m telescope with a fast electron-multiplication camera in the regime of partial turbulence correction by the visible-light adaptive opticsExpand
Lucky imaging of transiting planet host stars with LuckyCam
We obtained high-resolution, high-contrast optical imaging in the Sloan Digital Sky Survey i(') band with the LuckyCam camera mounted on the 2.56 m Nordic Optical Telescope, to search for faintExpand
High-contrast optical imaging of companions: the case of the brown dwarf binary HD 130948BC
Context. High-contrast imaging at optical wavelengths is limited by the modest correction of conventional near-IR optimized AO systems. We take advantage of new fast and low-readout-noise detectorsExpand
We describe the results from a new instrument which combines Lucky Imaging and adaptive optics (AO) to give the first routine direct diffraction-limited imaging in the visible on a 5 m telescope.Expand
Discovery of five very low mass close binaries, resolved in the visible with lucky imaging *
We survey a sample of 32 M5-M8 stars with distance 1 were found, even though our survey is sensitive to Am ≤ 5 (well into the brown dwarf regime). The distribution of orbital radii is in broadExpand
High spatial resolution and high contrast optical speckle imaging with FASTCAM at the ORM
In this paper, we present an original observational approach, which combines, for the first time, traditional speckle imaging with image post-processing to obtain in the optical domainExpand


High-resolution imaging in the visible from the ground without adaptive optics: new techniques and results
Many astronomical imaging studies, such as those of weak gravitational lensing, call for better angular resolution than is normally possible from the ground over wide fields of view . For many ofExpand
Noise free detectors in the visible and infrared: implications for the design of next-generation AO systems and large telescopes
This paper is intended to discuss the impact of noiseless CCD detectors in three significant areas of the development of large telescopes and the instruments that go on them. These are (1) CCDs thatExpand
USNO-B is an all-sky catalog that presents positions, proper motions, magnitudes in various optical passbands, and star/galaxy estimators for 1,042,618,261 objects derived from 3,643,201,733 separateExpand
Diffraction-limited CCD imaging with faint reference stars
By selecting short exposure images taken using a CCD with negligible readout noise we obtained essentially diffraction-limited 810 nm images of faint objects using nearby reference stars brighterExpand
Astronomical imaging with L3CCDs: detector performance and high-speed controller design
L3CCDs represent a major step in CCD performance with great potential for astronomical applications because of their ability to work at very high pixel rates with negligible readout noise. This paperExpand
Drizzle: A Method for the Linear Reconstruction of Undersampled Images
The photometric and astrometric accuracy and image fidelity of the algorithm as well as the noise characteristics of output images are discussed and the use of drizzling to combine dithered images in the presence of cosmic rays is described. Expand
Photon counting strategies with low-light-level CCDs
Low light level charge-coupled devices (L3CCDs) have recently been developed, incorporating on-chip gain. They may be operated to give an effective readout noise of much less than one electron byExpand
