Albireo but where’s the colour?

What a disappointment! While waiting for the short hours of darkness we experience at this time of year, I decided to image my favourite double star, Albireo (beta 1 Cyg), and beta 2 Cyg which have such wonderful colours in the eyepiece - gold and sapphire blue respectively. My 15s exposures were too much, and the halo surrounding the stars prevented me from drawing out any colour.

I’m posting this as a reminder to myself, to try again with much shorter exposures, perhaps layering these into the deeper starfield.

Description: Here's the best I can do with my LRGB data - Albireo is over-exposed, although I am quite happy with the overall starfield. I have added gentle star spikes to accentuate the lovely colours in this famous double star.

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.
