Benefits of Image Deconvolution in CCD Imagery

We show how wavelet-based image deconvolution can provide to wide-field CCD telescopes an increase in limiting magnitude of Δ R ∼ 0.6 and significant deblending improvement. Astrometric accuracy is not distorted, therefore, the feasibility of the technique for astrometric projects is validated. We a...

Sumario:We show how wavelet-based image deconvolution can provide to wide-field CCD telescopes an increase in limiting magnitude of Δ R ∼ 0.6 and significant deblending improvement. Astrometric accuracy is not distorted, therefore, the feasibility of the technique for astrometric projects is validated. We apply the deconvolution process to a set of images from the recently refurbished Baker-Nunn camera at Rothney Astrophysical Observatory.
