Two very weak and small nebulas RCW 89 and RCW 91 plus Pismis 20 and Lynga 3

These are two small and weak nebulas in Circinus, the blue and bright star is beta Circinus. Close to the centre and below right is RCW 91, and also near the centre up left is RCW 89. Also it is the open cluster Pismis 20, the small quite yellow cluster right close to the top at the centre of the image.

I found quite tricky the colour calibration in these full of dust areas and colourful stars, in general I try to find some reference images, normally from ESO, and using some routines in PxI for colour calibration to match a not so unbalance set of colours.

The Lynga 3 open cluster is clearly visible next to the bright yellow star, to the left, above RCW 91.

Additionally, close to the yellowish star at 12h12m and -58d45m it should be Loden 2045, however I am not able to identify it.

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.
