Emission-reflection nebulae IC4603 and IC4604.
Image
The Rho Ophiuchus Emission Nebula (IC4604) is located in the Ophiuchus constellation. It is an emission and reflection nebula. The star 5 rho Oph partially illuminates this nebula and makes it possible to see the nebula in a bluish color. In the image there is a lot of star dust, composed mostly of carbon. When these clouds are denser, they are opaque to visible light and can completely or partially cover the stars. In contrast, less dense clouds have the ability to preferentially reflect the blue light that reaches them. The brightest red tones typically correspond to gas emissions from the nebula. You can also see the IC4603 nebula where in its central part is the star HD 147889 that illuminates this blue reflection nebula.

Processed
The background was processed with a synthetic luminance mask from the signal of the three channels following the SNR criterion to reduce image noise. The stars were processed independently of the background nebulae stretched with GHS (Generalized Hyperbolic Stretch) and a star mask was applied in the G channel of the image.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
