NGC 3372 Carina Nebula in SHO under Full Moon (Martin Dowd)

NGC 3372 Carina Nebula in SHO under Full Moon

Revision title: NGC 3372 Carina Nebula Reprocessed

After nearly 3 months of cloudy nights , the 23rd January provided about 6 hours of clear skies to image but you guessed it, a near full moon was lighting up the sky.
As the ongoing forecast to at least late February early March was more cloudy nights , I decided to pick a big bright target like NGC 3372 and complete an imaging run in that small window of opportunity.
Clouds cleared around 10.30pm , locked on to the target and was imaging by 11.00pm
Finished my session at 4.30am after taking Flats ( total integration 3 hours )

Location : South Coast NSW
Skies : Bortle 3
Conditions : Average to Good Seeing
Full Moon
Very light wind ( 5 to 8 km/hr )
Thankfully no Dew

Quite happy with level of fine detail for only 3 hours of data

Thanks for Looking

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.
