Welcome Chris!
Pier 5 produces some great data, and I find the OSC images easy and fun to work with. I think you will enjoy it.
If we complete it, the Orion Mosaic will be a fantastic project, but big mosaics put a huge strain on processing. It's a lot of data. Hopefully, by doing it in stages, we will get useful images as we gradually build up to the mega-mosaic.
