Object: IC1805 The Heart Nebula	Emission Nebula	Const.: Cassiopeia
Camera: STL11000M	Scope: Tele Vue NP101is	Mount: Losmandy Titan
Filter(s): Hα:R:G:B	Exposure: 16x8m:5x8m:5x8m:5x8m	blank
IC1805 The Heart Nebula in Cassiopeia. This image is a color composite using a stack of 16 eight-minute exposures taken through an Hα filter (shown in the image below) as the luminance channel, and 5 eight-minute stacks each taken through red, green and blue filters for the colors. The images were acquired using an STL11000M CCD camera on a Tele Vue NP101is. The exposures were calibrated, defect-corrected, stacked and color-balanced using AIP4WIN V2. This image has been resampled down from its original size of 4008x2672.
