IC 342 in Camelopardalis



Scope: C8  f/5.1, Location: Dos Picos Park, Ramona, CA   3 December 2005  Camera: Artemis285

Exposure: 9 x 420 sec Luminance exposures with IR block, 7 x 150 sec (2x2 bin) RGB exposures.

Processing: Images were captured in Artemis Capture (as FITs). Aligned/stacked in Registax 3 and saved as FITS. Luminance and Color channels were scaled and rough color balanced in Astroart.  Channels were co-registered in Astroart. Final LRGB combine was done in Photoshop using Luminance Layering (or LLRGB). Luminance data from the earlier image was mixed in the luminance channel. Selective sharpening with layer mask was applied to galaxy dust lanes. Brighter star sizes were managed with a light minimum filter applied with mask. Photoshop was also used to subtract background noise from the luminance channel. Color balancing and final touches were done in Photoshop. SGBNR was used to smooth remaining background noise on the final result. Final Image size is approximately 1392x1040.

North is up in this image. The image was guided for all exposures. This object is mostly obscured by Milky Way dust. If not for this obscuring dust this object would approach the brightness of the Andromeda and Triangulum galaxies.  This image replaces an earlier image that can be seen in the Archives here.  Horizontal FOV is 24'

Image center is approximately - Equatorial 2000: RA: 03h 46m 48s Dec: +6805'44"
