Nebulae in Taurus - two RASA panels

Not sure if these strange creatures have any names or designations - I found them by surfing on Aladin Sky Atlas around M45. The blue binary star in the centre is Chi Tau. This is my first attempt of a two panel mosaic with the RASA8, so quite a wide field (two Andromeda galaxies would fit into the field of view). So these are very large but also very faint structures and I have here gone close to the limits of what this f/2 telescope combined with a very sensitive, low noise, 16 bit CMOS camera can achieve at this integration time.

Gain was set to 100 and this is a mix of 2 and 4 min exposures.

EDIT: Graham Darke on SGL has now informed me that the top half of the image shows Barnard 213, 216, 217 and 218. The lower part of the image is dominated by Barnard 215 and LDN1524. Thanks Graham!

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.
