CDK-17/Moravian c4/L-500 mount


This is one of those targets where you just can't collect enough data. I processed this in the HOO palette with two-thirds of the captured data, about 27 hours, being Ha. The Ha filter exposes ionized hydrogen which provides RCW 58 with its characteristic crimson hues and intricate detail. Alongside the prominent red are areas of the nebula that display shades of blue. This arises from the presence of ionized oxygen. It's an expansive nebula and lies in the southern sky within the Vela constellation. It showcases a tapestry of glowing gases, shaped by stellar winds and radiation from massive, young stars. These winds blow away surrounding material and carve out cavities within the nebula.
