| **Aim:** Images of an deep sky object shall be taken in different filters (R, G, B, IR, H_alpha, ...) with help of the CMOS camera (QHY-600). Afterwards they shall be calibrated and qualitatively interpreted at the computer. | **Aim:** Images of an deep sky object shall be taken in different filters (R, G, B, IR, H_alpha, ...) with help of the CMOS camera (QHY-600).

| **Method:** Observe with the STF-8300. Take also all necessary correction exposures. The data reduction follows and can be done by use of our scripts or with software chosen by the students. | **Method:** Observe with the QHY-600M. Take also all necessary correction exposures.

| Use the prepared [[en:praktikum:gdl|GDL]] scripts, which can be found at the [[en:praktikum:zugang |laboratory course computer]] (also see details of the [[en:praktikum:namenskonvention |name convention for files]]), to reduce the data photometrically. There are two scripts that do the principal data reduction (1_reduce_images.pro), the read-out, and the plotting of the photometry (2_obtain_flux.pro). Copy them to your local directory and adjust the names of the paths and the date of the current minimum. Compile and run the scripts with [[en:praktikum:gdl |GDL]] to obtain the light curve of the eclipsing binary star, which can be completed using archive data. | Use the prepared [[en:praktikum:gdl|GDL]] scripts, which can be found at the [[en:praktikum:zugang |laboratory course computer]] (also see details of the [[en:praktikum:namenskonvention |name convention for files]]), to reduce the data photometrically.
