Wizard Nebula - ASI1600 High Gain - Short Integration (Jon Rista)

Wizard Nebula - ASI1600 High Gain - Short Integration

The Wizard Nebula, my first fully complete narrow band tri-channel blend with data from the ASI1600. This image was created from high gain, short exposure data, and is overall a relatively short integration for narrow band. The exposure lengths were a mere 90 seconds for all three channels. Total integration acquired for each channel was about 2 hours each...however, only the full two hours was used to create an Ha channel that was used as luminance. I stuck with my original test integrations for the color channels, which ended up being very short integrations indeed:

Ha: 16x90s - 24m

OIII: 27x90s - 40.5m

SII: 35x90s - 52.5m

I guess I'm just being lazy at the moment, but I'd already achieved the two color palettes I wanted, and did not want to go through the full workflow from the very beginning (calibration) again to recreate them. Maybe in the future when I am less lazy, I'll integrate the full two hours for the other two channels and see if I can eek out more detail and/or color contrast.

Anyway, pretty satisfied at the moment with what's possible with extremely short integrations with this camera! I wouldn't call it top class, certainly better can be achieved with more integration, but for less than four hours of total exposure, I'm pretty happy.

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.
