IC4603 Rho Ophiuchi Complex

This is my first image with a new set of filters from Astrodon. It only uses the RGB, so I am anxious to try out the new 5nm Ha, Sii Oiii set. It is also only my second image with the MEII with absolute encoders. Such a joy to not need to do any guiding, which over the years has been a great source of frustration and lost imaging for me.

IC 4603 is a reflection nebula visible in the constellation of the Ophiuchu.

It is located in the southern part of the constellation, north of the red star Antares and is a small part of the Cloud of Rho Ophiuchi illuminated directly by the radiation of HD 147889, a blue giant of spectral class B2III located anteriorly to the densest part of the cloud, but completely surrounded by its gases. This star has a very reddish spectrum, which reveals that its light is filtered and partly masked by the cloud in which it is immersed; his young age indicates that it originated from a process of stellar formation within the same Cloud of Rho Ophiuchi. The measurements of the parallax, which provides a distance of 443 light years from the solar system, that is identical to that of the cloud, provides further proof of the link between these two objects.

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.
