IC5070 Pelican Nebula, HOYS target 118
HOYS NEEDS YOUR HELP
We’ve got a lot of images (~3,000) in our database that need a little processing done on them so that the data can be extracted. It’s not difficult to do and with a little help from you we can clear the backlog and get all that useful data into the database. If you can help please Get In Touch. Thanks
We are again a Global Sky Partner of Las Cumbres Observatory
