NGC2174 In Orion


Scope: ST80 f/2.5 Location: Dos Picos Park, Ramona, CA 1/10/2004 Camera: ToUcam SC3

Exposure: 15 x 20 sec, Exposure with IR Block, 10 x 120 sec HA exposure, 12 x 20 sec RGB Exposures.

Processing: Captured and stacked in K3CCDTools with HA, IR,R,G,B saved as FITs. HA, IR,RGB masters were co-registered in Astroart. Some Lowpass filtering was applied on the HA and IR channels. HA and IR were combined for Luminance. HA and Red combined for red. These combinations and LRGB combine were done in Photoshop. Luminance Layering was used. No ears - the exposure was made with RAW mode. Color balancing and final touches in Photoshop.

This was a guided exposure. This was one of my first images done with the RAW mode modification to the ToUCam SC3. This image is a nice example of the advantages to the RAW mode, there was no usual "repair" needed in the nebula region due to the "ears" artifacts common to this type of camera prior to the RAW mode modification. Horizontal FOV is 84'
