In this third chapter, the observatory finally takes shape. Together with my friend Iván Campo, I build the sliding roof, complete the electrical installation, paint and varnish the floor, and install the automatic motor that opens and closes the roof effortlessly. Finally, I move my telescopes —the Newtonian, ED80 refractor, and FF107— into their new home. This final stage is dedicated to Nicolás Turienzo Robles, whose memory now shines among the stars we watch at night.

In the final episode of the PixInsight tutorial, we complete the workflow using Statistics, MaskedStretch, CurvesTransformation, RangeSelection, StarMask, PixelMath, LocalHistogramEqualization, NoiseXTerminator, and ACDNR — enhancing detail and reducing noise for a balanced, ready-to-share image.

In the fourth episode of the PixInsight tutorial, we explore Deconvolution, along with DynamicPSF, StarMask, and RangeMask, to recover fine detail with precision. We also dive into BlurXTerminator, the innovative AI-powered tool by Russell Croman that enhances sharpness and structure in astrophotography images.

In the third episode of the PixInsight tutorial, we explore key tools for advanced calibration and correction: ImageSolver, SpectroPhotometricFluxCalibration, MultiscaleGradientCorrection, SpectroPhotometricColorCalibration, and SCNR. An essential step toward accurate and balanced astronomical images.

After the demolition of the old stables, the most exciting moment of the project arrives: beginning to build the astronomical observatory. In this second part, I describe how we prepared the foundations and the central column, the true heart of the observatory, and how Beatriz added her personal touch by creating an access path. Finally, between August 28 and 29, 2025, the dream began to take shape with the erection of the walls and the installation of the gate.

En el segundo episodio del tutorial de procesado con PixInsight exploramos tres herramientas esenciales: ImageIntegration, para combinar tus tomas; ScreenTransferFunction, para visualizar datos lineales; y DynamicCrop, para ajustar el encuadre final. Un paso clave hacia imágenes más limpias y equilibradas.
