IC1311 and friends

This is a first light image with my new ASI6200MM that was intended more as a test, but evolved into a new project. I started this project with a QHY16200A on the same scope, and wanted more data with this, but in the end liked the wider field so much more that I went with this data. This is all taken in one night, and due to poor planning on my part (I didn't expect the data to be that clean), I only have 3 Ha and 4 SII exposures. The OIII in this region is pretty faint, so that's why I concentrated on that to get the noise down. I still have some spacing issues to resolve, which should be done when my new adapter comes in. In comparing the OIII channel from this camera, and the QHY16200A, it was a night and day difference.

It seems gain=100 will be a good test to do as well. Early indications show a lot of improvement at gain=100 vs. gain=0 for narrowband with only a minor impact on dynamic range. This was taken with Gain=0, Offset=0, but I had previously built my bias/dark library with offset=50. I had to get creative with the dark subtraction, but honestly this sensor is so clean I probably didn't have to do that.

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.
