Little Rosette Nebula Sh 2-170 and LBN 576, "a study in black and white", 2-panel mosaic

Due to a lack of clear inspiration about what to image, I made the spontaneous decision to capture data for a two-panel mosaic. Certainly, the present moon phase was a main driver to restrict the imaging to narrowband, namely Ha. The selection of the objects was done based on "what culminates at 1 AM?". Since I couldn't decide if I should go for the Little Rosette or supernova remnant LBN576, I decided to give a two-panel mosaic a chance. Of course, the mantra "exposure time can only be substituted by more exposure time" always holds and more data would improve SNR, there's certainly no lack on the Little Rosette. On the other hand, the significant under-sampling doesn't call for a 100% view and the image is best viewed at lower magnifications.

The image metadata states about 9 hours of total intergration time which is roughly split 50/50.

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.
