North America complex in Bi colour (15 pane mosaic)

This is my biggest ever project.

A 15 panel mosaic of the North America nebula region shot with both my setups at the same time.

I used my ASI294MC Pro with the AT106 to shoot Tri-band and Ha and my QHY183M on the TS65Q to shoot Ha and Oiii so the total integration time is 150 hours but the imaging time is half of that.

Before the mosaic I have the cameras swapped between the 2 scopes but I changed them over for a closer field of view and pixel scale between the 2.

I started shooting the mosaic in April this year and I finished it last month.

Using APP, I extracted the Ha shot with the 294 and Ha filter and the Ha and Oiii shot with the tri-band. After that I stacked all the Ha and Oiii for each panel and blended them all in APP.

I used pixinsight Starnet++ to remove the stars from both Ha and Oiii, I blended them into the HOO image and worked on it until I was ready to put the stars back.

I'm really pleased with the result, it might not be perfect but I can say that it's my best astro image.

I hope you like it too.

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.
