Lagoon Nebula in HaRGB, with an uncooled CMOS

This is my first ever work with a mono camera. I was a bit unlucky with the weather, especially for shooting the color frames I didn't have one decent night without low clouds on the horizon, where M8 is positioned from my latitude. Nevertheless I am very happy with the outcome, it relly surpassed my expectations! When I got the GPcam3 178M I was slightly nervous about how well it would perform for DSO imaging, since it is uncooled. But the low dark current and read noise really work out like I hoped they would.

I used Starnet++ to produce a starless Version of the Ha Channel and the tone mapping techniques from Josh Smith's Youtube channel to tease out the Detail.

Before my next project, I plan to invest night into getting the correct Sensor-Reducer spacing, since there is some coma in the stars away from the optical axis.

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.
