NGC 5033 in Canes Venatici


Scope: C8 f/3.2; Location: Blair Valley, Anza Borrego Desert, CA; 7 May 2005; Camera: ToUcam SC3

Exposure: 16 x 90 sec and 16 x 24 sec Luminance exposures with IR Block Filter; 12 x 60 sec RGB 

Processing: Images were captured in K3CCDTools 2. Aligned/stacked in Registax 3 and saved as FITS. Luminance and Color channels were scaled and rough color balanced in IRIS. Channels were co-registered in IRIS.   LRGB Channels were resized to 800x600 prior to LRGB combine. Luminance and Color FITS were combined in Photoshop with Luminance Layering. This image was aggressively processed to bring out faint aspects of the spiral arms. The object was lassoed and stretched separately.  Some star repair was performed on the brighter stars to reduce bloat. Color balancing and final touches in Photoshop (including background noise subtraction on the Luminance master). SGBNR  (PixInsight LE) was used to smooth remaining background noise on the luminance channel and the final result. Very light Richardson-Lucy de-convolution was applied to the luminance channel and re-blended with the original luminance prior to LRGB combine. Final size  approximately 800x600.

This image was a guided image. North is up. The view of this galaxy reveals some delicate spiral arms. It is located in the constellation of Canes Venatici about 38 million light years distant. Horizontal FOV is about 27'

Image Center is approximately Equatorial 2000: RA: 13h 13m 28s Dec: +3635'36"
