Carina HOO + RGB stars

Yup another Carina! This one has a funny story though: as I was capturing my Ha and Sii sub-frames for the upcoming Ara's Dragon 2x2 mosaic, I noticed that from my Bortle 9 skies I would need to push my mount to get at least 5 min subs if I wanted to actually get any data to show. And this is no easy task when you're imaging with an RC6.

At the end of the night, it worked relatively well, although a huge chunk of the sub-frames contained very funny-shaped stars and were discarded. Now HOLD UP A MINUTE! Stars are bright, aren't they? If I'm already combining three different narrowband channels to get my color image, why not combine some RGB stars and replace them in my narrowband channels instead? I'm pretty sure I saw someone doing this on Reddit or something.

And of course, I had to try it. Carina was the obvious choice, because it's still high in my Southern sky for a relatively good time, but I didn't even need to use that long: all I did was take a few minutes of 5's for each channel (R, G, B) and then re-visit my previously obtained HOO data. And I must say, this is a game changer for me. Not only the stars are way better shaped, but we get to see more stars now, and with so much more beautiful colors!

The downside? Now I can't take any more SHO proejcts without also capturing RGB stars. Whew.

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.
