LDN 1355 - the zone of avoidance

Peering into the Zone of Avoidance:
The zone of avoidance is the region of the milky way which blocks out our view of the universe behind due to the exctinction of visible light caused by the dust our of our milky ways band. This region contains a lot of fascinating yet extremely dim "Dark nebulae" which dont emit light of their own and rely solely on background illumination to be seen.
LDN 1355,1357 and 1358 are an example of such nebulae, also collectively known as the helping hand nebula in the Cassiopea constellation.
To the left of the hand is the beautiful reflection nebula, VdB 9 which is illuminated by the blue star SU Cas. Bringing out the delicate wisps of the reflection nebula were a challenge in this image.
There is another reflection nebula, VdB 7 to the bottom left along with a lot of diffuse blue structures floatinf along the dark gas.
This image is our longest integration yet. We focused on bringing out all of the background dust and the final image really gives us an idea of how densely packed the zone of avoidance is, which obstructs our view in visible wavelenghts of galaxies or objects behind.
This image is equivalent to almost a day of collecting light, and that even from the darkest skies of Balochistan!

Captured at Taqwa Space Observatory, Pakistan's only privately owned dark sky observatory (bortle class 1) located in the province of Balochistan.

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.
