This image shows SH2-54, an emission nebula just north of the Eagle Nebula in Serpens in Hydrogen-alpha light.
This image was acquired using an SBIG STL11000M CCD camera mounted on a Tele Vue NP127is.
This image is a stack of 8 eight-minute exposures that were calibrated, defect-corrected and stacked using AIP4Win Version 2.
The new Sigmoid Scaling feature of AIP4Win V2.1.10 was used to compress the extreme dynamic range of this image in order to
display the tremendous amount of nebulosity in this region of the sky.
This image has been resampled down from its original size of 4008x2672.
