This was my first mosaic - I did it with Pixinsight. Overall exposure of this image is 12.7 hours (3+ hours Ha, 5 hours OIII, 4.5 hours SII).
Unfortunately, I am still fighting with vertical and also horizontals stripes in my images. You can see it in the lower right corner. But apart from that, I quite like it.
