Autor: Mackay, Craig, Rebolo, Rafael, Crass, Jonathan, King, David L., Labadie, Lucas, González-Escélera, Víctor, Puga, Marta, Pérez-Garrido, Antonio, López, Roberto, Oscoz, Alejandro, Pérez-Prieto, Jorge A., Rodríguez-Ramos, Luis F., Velasco, Sergio, Villó, Isidro

Lucky Imaging combined with a low order adaptive optics system has given the highest resolution images ever taken in the visible or near infrared of faint astronomical objects. This paper describes a new instrument that has already been deployed on t

AOLI-- Adaptive Optics Lucky Imager: Diffraction Limited Imaging in the Visible on Large Ground-Based Telescopes

Autor: Mackay, Craig, Rebolo-López, Rafael, Castellá, Bruno Femenia, Crass, Jonathan, King, David L., Labadie, Lucas, Aisher, Peter, Garrido, Antonio Pérez, Balcells, Marc, Díaz-Sánchez, Anastasio, Fuensalida, Jesús Jimenez, Lopez, Roberto L., Oscoz, Alejandro, Prieto, Jorge A. Pérez, Rodríguez-Ramos, Luis F., Villó, Isidro

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 4.2m and GTC 10.4 m telescopes on La Palma, with particula

Report

High-resolution optical imaging of the core of the globular cluster M15 with FastCam

Autor: Díaz-Sánchez, Anastasio, Pérez-Garrido, Antonio, Villó, Isidro, Rebolo, Rafael, Pérez-Prieto, Jorge A., Oscoz, Alejandro, Hildebrandt, Sergi R., López, Roberto, Rodríguez, Luis F.

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. Short exposure times (30 ms) were used to record 200000 images

Report

High spatial resolution and high contrast optical speckle imaging with FASTCAM at the ORM

Autor: Labadie, L., Rebolo, R., Femenia, B., Villo, Isidro, Diaz-Sanchez, A., Oscoz, A., Lopez, R., Perez-Prieto, J., Perez-Garrido, A., Hildebrandt, S. R., Bejar-Sanchez, V., Piqueras, J., Rodriguez, L. F.

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 domain diffraction-limited images with high contrast (1e-5) within 0.5 t
