Object: The Crescent NebulaNGC6888 and IC1318	Emission Nebula	Const.: Cygnus
Camera: SBIG STL11000M	Scope: Tele Vue NP127is	Mount: Losmandy Titan
Filter(s): Hα:Hα:G:B	Exposure: 18x8m:18x8m:7x8m:7x8m	blank
This image shows the emission nebulae IC1318 and NGC6888 (a.k.a The Crescent Nebula) in Cygnus. This image was acquired using an SBIG STL11000M CCD camera mounted on a Tele Vue NP127is. This image uses a stack of 18 eight-minute exposures taken through a Hydrogen-alpha filter for both the luminance and red channels. The green and blue channels are stacks of 7 eight-minute exposures taken through green and blue filters. The images were calibrated, stacked and color-combined using AIP4Win V2. This image has been resampled down from its original size of 4008x2672.

 

Object: NGC6888	Emission Nebula	Const.: Cygnus
Camera: SXV-H9	Scope: Tele Vue NP-101	Mount: Losmandy Titan
Filter(s): Hα:L:R:G:B	Exposure: 90m:64m:8m:8m:8m	TeleVue 0.8x Focal Reducer
NGC6888, the Crescent Nebula in Cygnus. This HaLRGB color composite was made using 90 minutes of Hydrogen-alpha filtered data blended with 64 minutes of unfiltered data for the luminance channel, combined with stacks of 8 eight minute exposures for each of the R, G & B channels, using AIP4WIN. The images were taken using an SXV-H9 CCD camera on an NP-101 equipped with a 0.8x focal reducer. This image has been resampled down from its original size of 1381x1026.

 

Hydrogen-α
Object: NGC6888	Emission Nebula	Const.: Cygnus
Camera: SXV-H9	Scope: Vixen R200SS	Mount: Losmandy Titan
Filter(s): Hα	Exposure: 10x8m	Taken during a full moon
NGC6888, the Crescent Nebula in Cygnus. 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 exposures were calibrated, defect-corrected and stacked using AIP4WIN. Wavelet Sharpening was applied to enhance the structure. The image was acquired during a full moon. This image has been resampled down from its original size of 1392x1040.

 

Object: NGC6888	Emission Nebula	Const.: Cygnus
Camera: HX-916	Scope: AP130	Mount: AP1200GTO
Filter(s): L:R:G:B	Exposure: 31x2m:16x2m:16x2m:16x2m	Color channels binned 2x2
NGC6888, the Crescent Nebula in Cygnus. This LRGB color composite was made using the 1 hour image below for the luminance channel, combined with stacks of 16 two minute subsampled exposures for each of the R, G & B channels, using AIP4WIN. This image has been resampled down from its original size of 1196x948.

 

Object: NGC6888	Emission Nebula	Const.: Cygnus
Camera: HX-916	Scope: AP130	Mount: AP1200GTO
Filter(s): IR block	Exposure: 31x2m	blank
NGC6888, the Crescent Nebula in Cygnus. A stack of 31 two minute exposures using a 5" f/6 refractor. The individual image frames were calibrated, defect-corrected and stacked, and a Gaussian unsharp mask was performed, all using AIP4WIN. This image has been resampled down from its original size of 1248x989.
