R136a is the core of the ionizing cluster NGC 2070 at the center of the 30 Doradus nebula in the Large Magellanic Cloud. The interesting question is whether R136 is a supermassive object or whether it is a dense star cluster. We propose FOC f/288 imaging and roll deconvolution in order to solve the question. Roll deconvolution of FOC f/288 data can yield exactly diffraction-limited resolution, for example, 0.02" at lambda = 200 nm. The same observations are proposed in order to study the nature HD 97950 AB in NGC 3603 and Eta Carinae. HD 97950 in NGC 3603 is probably of similar nature as R136. Objective prism observations are proposed in order to perform speckle spectroscopy of R136a and HD 97950 AB. Speckle interferometry observations (object autocorrelations) show that all 3 objects can be resolved with the ST. Only FOC f/288 measurements can yield the required resolution since only in the case of f/288 data the pixel size is small enough.
