The Rosette Nebula
Taken with the Canon Rebel T3 80MM Nexstar HA Filter Guided ..total of 350 seconds exposure
Had tried this before without the filter and no or little nebulosity visable..
Image was taken in colour then converted to Grayscale in P/shop
Set Levels and Contrast then Hue Added unsharp mask filter for final
This is a rehash of the same 78 megabite image with less noise..Better I think
