Object: M83 (NGC4374)	Spiral Galaxy	Const.: Hydra
Camera: STL11000M	Scope: TEC 200FL	Mount: AP1200
Filter(s): L:R:G:B	Exposure: 5x8m:4x8m:4x8m:4x8m	blank
The galaxy M83 in Hydra. This image is a stack of 5 eight minute exposures using an SBIG STL11000M CCD camera on a TEC 200FL 8" f/8 refractor for the luminance channel, with stacks of 4 eight minute exposures each for the red, green and blue channels. The image was calibrated, defect-corrected, stacked and Sigmoid-scaled using AIP4WIN V2.3.0. This view is a crop from the full 4008 x 2672 frame. Clicking on it will show the whole frame. /font>

 

Object: M83 (NGC4374)	Spiral Galaxy	Const.: Hydra
Camera: HX916	Scope: Vixen R200SS	Mount: Losmandy Titan
Filter(s): IR block	Exposure: 63x60s	TeleVue Paracorr
The galaxy M83 in Hydra. This image is a stack of 63 sixty second exposures using a Vixen R200SS 8" f/4 Newtonian with a coma corrector. It was tough to shoot, as it only gets 12 degrees above the horizon from my observatory, and at its highest point is surrounded by the light dome from NYC and northern NJ, so there is a fair amount of light pollution and unsteady air to contend with. The image was calibrated, defect corrected and stacked, followed by 5 iterations of Richardson-Lucy deconvolution, then a simple linear stretch was performed, all using AIP4WIN. This image has been resampled down from its original size of 1200x960.
