Here is the English translation of the astrophotography text, with HTML tags, astronomical designations, equipment names, and numbers preserved:

This image of the Rosette Nebula (Caldwell 49) was captured over several nights in January 2024 from a Bortle 4 site using a William Optics RedCat 51 apochromatic refractor and a cooled ZWO ASI2600MM Pro camera. A total of 18 hours of integration time was collected through Ha, OIII, and SII narrowband filters (7 nm bandpass).

Processing was done in PixInsight using the Hubble Palette (SHO) mapping, followed by noise reduction with BlurXTerminator and NoiseXTerminator. The final image highlights the intricate filaments and dark globules of the nebula, located approximately 5,200 light-years away in the constellation Monoceros.

Anya, was it out of focus or was the guiding terrible? More likely the first, considering the sub-exposures were only a minute long.
