M58 Region in Virgo



Scope: Explore Scientific MN152  Maksutov Newtonian at f/4.8, Location: Laguna Mountains, CA   5 April 2014  Camera: Atik 383L

Exposure: Exposure: 16 x 9 min  (1x1 bin) exposure with UV/IR block, 8 x 4 min (2x2 bin) RGB exposures.

Processing: Data Collection -  Artemis Capture (as FITs).  Calibrated, stacked (Kappa Sigma Combine) Deep Sky Stacker.  LRGB channel registration, equalization - Astroart.  Central Gradient Removal - Astroart. Curves, Levels, LRGB combine and finishing  - Photoshop. This image is a straightforward LRGB combine with Luminance layering.     Final Image size is approximately 3354 x 2529 resized to 2800 x 2100.

North is to the left in this image.  M58 is the large spiral in the lower part of the image. NGC 4567 and NGC4568 are the colorful pair to the right in the image. Just to the left of the pair is the elliptical galaxy NGC  4564. In the upper left are NGC 4550 and NGC 4551 - the former is considered a galaxy with an active disk-like nucleus (so called type II LINER).  Also in the image (at the very bottom edge in the middle) is WOLF 433 - am orange/red star with a high proper motion (meaning it has a relatively high velocity compared to our solar system). There are several other galaxies in this field as well, these plus the ones I have mentioned can be more easily identified in the annotated image.  M58 is about 60 million light years distant from Earth; NGC 4567, 4568 are about 54 million light years distant; WOLF 433  a much close 47 light years Horizontal FOV is 88'

Image center is approximately - Equatorial 2000: RA: 12h 36m 40s Dec: +1141'19"
