NGC 6888, the crescent, another try
clik the image for a larger file..

Moving in on it, needs now a series to get the O2 layer.... one hour, 12 x 300 seconds at f5.8 . Buried in the Milky Way, the
background is a rippled cloud of slightly excited hydrogen, brownish, like around the Orion complex.
I have no detail in it yet, but perhaps longer subs will do it...

acquired, calibrated, stacked and processed with darks and flats in Nebulosity,
post processing (saturation, contrast) in Photoshop CS3, no sharpening or noise reduction.
