I've decided to add another observing project to supplement my Abell Planetary Nebula. I am going to go after some of the ARP galaxies. To assist me with this, I am making a Google Sheet that has the ARP's by name and by season. I hope this may help others to find a fun observing challenge to go after! Here is the LINK
I also just found these resources on the Astronomical League's Page:
