IC4605, IC4603, and M4 - Antares region

This is a trial run - only about 30 minutes into this image. First light for my HEQ5 mount (unguided) in combination with the little SV70t.

My digital atlas says:

Highlighted by the bright star Antares, the region provides an impressive spectacle of colorful glowing gases, juxtaposed with converging dark rivers of thick dust. Other areas of nebulosity within the region include IC 4603, centered around the star SAO 184376; and IC 4605, around 22 Scorpii. The nebulosity around Antares itself (α Sco) is designated IC 4606. Dark nebulae Barnard 45 and Barnard 42 separate the reflection nebulosity near ρ Oph (IC 4603 and IC 4604) from the nebulosity closer to 22 Sco and Antares (IC 4605 and IC 4606). Barnard 44 lies to the east.

My stars are not the best, but I'm not too worried as I will have a small guide scope soon (thanks to my friend Mark in Toronto - salut! ) and will bring guiding into my repertoire in the near future.

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.
