Abstract
We present bispectrum speckle interferometry of the massive protostellar object NGC 7538 IRS1 in the near-infrared K’band. Our observations were carried out on the 6.5 m Multiple Mirror Telescope (MMT) using our speckle visitor camera. The recorded speckle interferograms were used to reconstruct images with high dynamic range.
