Lagoon QHY268-M First Light

This is a first light image with new QHY268M-PH camera. Kept same filter wheel and 36mm filters I have been using with the QHY294M. Used sky flats exposed to ~28000 ADU with ACP autoflats script. The image is 10x180sec each R,G,B,&H all at gain=0 with offset of 40. Camera temperature set to -10C. As I am imaging right over the top of Dallas metro close by to the south I applied gradient correction to each master before combination. Made the RGB, used BlurX just to correct - no sharpening - and then color corrected with SPCC. Removed stars from the Ha and added the linear Ha to the linear RGB in NBColourmapper script with Ha layer saturation at 0.8. Masked stretch followed by brightening with GHS and curves. Applied very mild noise reduction with NoiseX (0.2). Applied PI auto gradient correction a final time with auto convergence and protection masks enabled.

I think for this bright area with camera at gain=0 180sec RGB subs at a bit too long. Seemed about right for the Ha. As always thank you so much for looking!

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.
