Object: M16 (NGC6611)	The Eagle Nebula - Emission Nebula	Const.: Serpens
Camera: SBIG STL11000M	Scope: Tele Vue NP127is	Mount: Losmandy Titan
Filter(s): Hα:R:G:B	Exposure: 8x8m:4x4m:4x4m:4x4m	blank
This image shows the region around M16, Eagle Nebula in Serpens in color. This image was acquired using an SBIG STL11000M CCD camera mounted on a Tele Vue NP127is. This image is a color composite, using a stack of 8 eight-minute exposures through an Hα filter for the luminance channel, and stacks of 4 four-minute exposures through red, green and blue filters for the color channels. The Hα image below was used for the luminance channel. This image has been resampled down from its original size of 4008x2672.

 

Hydrogen-α
Object: M16 (NGC6611)	The Eagle Nebula Emission Nebula	Const.: Serpens
Camera: SBIG STL11000M	Scope: Tele Vue NP127is	Mount: Losmandy Titan
Filter(s): Hα	Exposure: 8x8m	blank
This image shows the M16, 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.

 

Object: M16 (NGC6611)	The Eagle Nebula - Emission Nebula	Const.: Serpens
Camera: SXV-H9	Scope: Vixen R200SS	Mount: Losmandy Titan
Filter(s): Hα:R:G:B	Exposure: 10x8m:4x8m:4x8m:4x8m	TeleVue Paracorr
M16 - The Eagle Nebula in Sagittarius. This image uses the hydrogen-alpha image at the bottom of this page for the luminance channel and 4 eight minute exposures for each of the red, green and blue channels. The hydrogen-alpha image was acquired with an SXV-H9 CCD camera on a Vixen R200SS 8" f/4 Newtonian equipped with a Paracorr. The color images were acquired with an SXV-H9 CCD camera on a Tele Vue NP127 5" f/5.2 refractor. The exposures were calibrated, defect-corrected, stacked and G2V-balanced using AIP4WIN V2. The Ha image was Wavelet filtered to enhance its sharpness, using AIP4Win V2. What is interesting to consider here is that the Ha and color channels were taken over a year apart on two different telescopes. This image has been resampled down from its original size of 1392x1040.

Hydrogen-α
Object: M16 (NGC6611)	The Eagle Nebula - Emission Nebula	Const.: Serpens
Camera: SXV-H9	Scope: Vixen R200SS	Mount: Losmandy Titan
Filter(s): Hα	Exposure: 10x8m	Acquired under a nearly-full moon
The Eagle Nebula in Serpens. This image is a stack of 10 eight minute exposures shot through a Hydrogen-alpha filter. The exposures were acquired using an SXV-H9 CCD camera on a Vixen R200SS 8" f/4 Newtonian equipped with a Paracorr. The image was acquired under a moon that was 1 day past full. The exposures were calibrated, defect-corrected and stacked using AIP4WIN. Wavelet sharpening was applied to enhance the structure. This image has been resampled down from its original size of 1392x1040.
