Description

After many months of disruption on a personal level, the first image from the backyard after moving back into our house. Our patio is in pieces, so balancing the tripod was interesting. But it was just nice to get back out there!

A full moon night meant that I was always going aim for something that was transiting North, so the Heart fit the bill.

This could also be the last time I use the CEM25P for an image for a while...I've recently upgraded my mount.

I added Ha to Lum using a 35:65 ratio and also added Ha to the Red channel using a 70:30 ratio. I masked the stars, so they would stay RGB.

Thank you for looking and for reading this far!
