After nearly 3 months of cloudy nights on the east coast of Australia , 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 )
Due to my set up I can only fit 50% of this beautiful nebula in my FOV
