Here's my latest narrowband capture of the Rosette Nebula (NGC 2237) and Cone Nebula (NGC 2264) in Monoceros, shot in SHO. This was a long integration over multiple nights, processed to bring out the finer structural details in the gas while maintaining a natural dynamic range.

Rosette Nebula (Top Right)
At ~5,200 light-years away, the Rosette is a classic H II region, with NGC 2244 at its core blowing out a well-defined cavity. O-type stars in the cluster are driving strong UV radiation into the surrounding gas, ionizing the oxygen (OIII) and creating the bright blue glow in the outer layers. You can see well-developed shock fronts in the sulfur and hydrogen bands, especially along the dense ridges where star formation is still ongoing.

NGC 2264, at ~2,600 light-years, is a much more chaotic star-forming region. The Cone Nebula is visible as a dark, tapering structure, formed by intense stellar winds pushing against a dense molecular cloud. The surrounding nebulosity is shaped by newly formed stars, with oxygen-rich regions (OIII) glowing blue and hydrogen/sulfur-dominant areas (Ha/SII) appearing in warm tones.  

Acquisition & Processing
Captured with the asi 294mm pro and 3nm chroma filters. This is an SHO-blend, with some dynamic range tweaks to avoid overpowering the blues. I spent extra time balancing the contrast in the faint outer filaments while keeping the core structures sharp. Used a combination of deconvolution, local contrast enhancement, and multi-scale sharpening to bring out fine details without introducing artifacts.  

This region never disappoints—so much depth and complexity in the interplay between radiation and dust. Let me know what you think, and clear skies!
