Double stars astrometry

First double stars astrometry data was collected starting from 2010 using Nexstar telescope and the Imaging Source camera. Unfortunately using this setup the measuring process was quite time consuming , so only a small number of neglacted objects was measured and reported in two articles published in Jurnal of Double Star Observations. The articles can be seen here:

A different approach was used using the current semiautomatic setup (with the CPC800) and resulted a new series of measurement. Having a much bigger field the images could be reduced directly with Astrometrica software one measurement could be made from a single image without extra calibration frames ( except the darks and flats ) reducing very much the observing time for each object. Also field rotation correction was not necessary anymore. The drawback is that I was able to target only medium and big separation objects ( over 5-6 arcsec separation ) Still another advantage of this new approach is that I could target lower magnitude doubles (probably down to 16 mag or more) than with the other setup. The first results with this approach can be seen in the following paper from Jurnal of Double Star Observations

After a succesfull datamining for double stars project on the VLT Survey telescope presented in the following paper in Journal of Double Stars Observations in 2017 ( ) some new ideeas started to grow . With small modifications some tools from the EURONEAR project might became a valuable and eficient help for the double star datamining activity. With the permission of the EURONEAR teams I reused their ideea and some source code and produced a set of such tools. The final result was presented in a new paper in Journal of Double Stars Observations in 2019 : and reporting also some new double star measurements from the VLT Survey telescope as a demonstration for the new tools. After a few more years a new datamining project was completed using the new tools on the 4m Victor Blanco telescope and the DECam huge CCD resulting a new set of measurements presented in a new paper:
