NGC 2903 is a barred spiral galaxy located in the constellation Leo, about 30 million light-years from Earth. Its structure is similar to that of the Milky Way, featuring a bright nucleus, a well-defined central bar, and spiral arms rich in gas and dust where new stars are being formed. Discovered by William Herschel in 1784, this galaxy is one of the brightest deep-sky objects not included in the Messier catalog. Its star-forming regions, visible as reddish areas of ionized

In this post, we present new data on the open cluster M36, a young collection of stars located in the constellation Auriga, approximately 4,100 light-years from Earth. Through observation and analysis, we explore its main physical characteristics and its relevance to the study of stellar evolution, focusing on details that emerge beyond the visible spectrum. This new addition expands the available data.

Discover the fascinating planetary nebula M76 (NGC 650/651), a rare bipolar object in Perseus. We explore its formation process, the story of its 'dual identity,' and the shocking 120,000°C temperature of its central white dwarf. Includes technical details of the acquisition from the Lyra Observatory and the download of raw data for the community.

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.
