Description

Here is the combined RGB + Duo Band version of my Lagoon Nebula.  Its 10 hours of Ha Oii Duo band (L-Extreme) combined with 1.5 hours of RGB (L-Pro). I took this in 4min subs on a Star Adventurer Pro2 with an ASI 522 MC Pro though and ED72 guided. I processed in Pixinsight and Photoshop. Bortle 5 on average. I cool the camera down to -10deg and fully calibrated the images.
