NGC 5078 and NGC 5101 in Hydra



Scope: Celestron 9.25 Edge 235 mm at f/7, Location: Tierra Del Sol - SDAA Club Site, CA,  15 April 2018  Camera: ST8300M (Baader LRGB filters)

Exposure: Exposure:  10 x 10 min (1x1 bin) and 8 x 12 min (2x2 bin) exposure with IR/UV Block filter, 8 x 4 min (2x2 bin) RGB exposures.

Processing: Data Collection -  Sequence Generator Pro (as FITs).  Calibrated, stacked (Kappa Sigma Combine) - Deep Sky Stacker. LRGB channel registration, equalization, gradient removal - Astroart.  Curves, Levels, RGB combine - ImagesPlus. Luminance Layering, final stretch, and finishing  - Photoshop.  RGB calibration - eXcalibrator. This image is a  RGB combine with Luminance layering.  Color saturation in LAB color.  The IR/UV Blocking filter exposure stack was used for the luminance layer. High pass sharpening applied. Images processed at 3352 x 2532 resolution. Final Image size is approximately  2800 x 2100.

North is up in this image.   NGC 5101 is the face on, barred spiral galaxy on the left. NGC 5078 is the edge on spiral galaxy on the right. Further to the right of NGC 5078 is the galaxy IC 870 which has the additional entry as IC 4222. These three galaxies are part of the galaxy group [CHM2007] HDC 782. This group has  six members - three in this field that only captures the Southeast quadrant of the group's angular area.  The three galaxies are from 73 to 120 million light years distant. There are numerous background galaxies in this field  - some with distances estimated by redshift to be over a billion light years distant. These galaxies and some of the brighter stars are identified in the annotated image..   Horizontal FOV is approximately 38 arc minutes.

Image center is located approximately - Equatorial 2000: RA: 13h 20m 46s Dec: -2724'53"
