A Cosmic Duo - SH2-9 & M4 in HaLRGB (Andy 01)

A Cosmic Duo - SH2-9 & M4 in HaLRGB

Sh2-9, also called Gum 65 is combination emission and reflection nebula in the Scorpius constellation, surrounding the multiple star system Sigma Scorpii. The nebula is northeast of the globular cluster, Messier 4.

Although it was a tricky challenge to image this under my suburban Bortle 6/7 skies, I'm quite pleased with the outcome. The complimentary colours of cool Al-Niyat and warm M4 seem to balance one another nicely. The big Tak has it's spacing perfect now, so I finally have round stars in all four corners, and the star definition in M4 itself is remarkable.

I've ordered a new TOA-35 reducer to give me a wider FOV, so when that arrives, I'll be able to frame some of these larger objects with a bit more "space" to allow context.

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.
