Coffee Bean Nebula (RCW98): A Different Roast

There are less than ten images of RCW98 that I can find on Astrobin. Most are broadband, with one narrowband image using the same Telescope Live data as I am using here.

This is perhaps not surprising, since RCW98 is a small, faint target with very weak [OIII] so most NB palettes don't produce a very colourful image. On the other hand the star field arond RCW98 is quite colourful and so broadband images are. perhaps, more pleasing to the eye.

In trawling through the Telescopes Live back catalogue, I noticed that RCW98 has quite a lot of [SII] and so I thought it might be fun to put together a Foraxx-inspired HSS pallettee (i.e. the Foraxx HOO with O replaced by S]. I was pleasantly surprised by the result. While still not the most colourful of DSOs, this approach does bring more colour into the NB image of RCW98 - indeed it ends up being a little more coffee-coloured.

This actually inspires me to do more of the faint RCW targets in HSS - at least for those that have appreciable [SII]. Certainly this palette is much more tolerant of bright moon, and so it might be fun to explore.

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.
