This image shows the Lagoon and Trifid Nebulae in Sagittarius 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 14 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.
 
Hydrogen-α

Object: M8 (NGC6523)
The Lagoon Nebula - Emission Nebula
 Const.: Sagittarius
Camera: SXV-H9 Scope: Vixen R200SS Mount: Losmandy Titan
Filter(s): Hα Exposure: 5x8m TeleVue Paracorr
The Lagoon Nebula in Sagittarius. This image is a stack of 5 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 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.
