This image shows Sh2-54, an emission nebula just north of the Eagle Nebula in Serpens.
This image was acquired using an SBIG STL11000M CCD camera mounted on a Tele Vue NP127is.
This image uses a stack of 8 eight-minute exposures taken through a Hydrogen-alpha filter
for the luminance channel, combined with 4 eight-minute exposures taken through red, green
and blue filters for the color data. The Hydrogen-alpha luminance image is shown below.
The images were calibrated, defect-corrected, stacked, G2V-calibrated and color-combined using AIP4Win Version 2.
This image has been resampled down from its original size of 3825x2417.
