For finding pictures of specific exoplanets very few have been directly imaged. You should at least be able to go and find schematics, diagrams, data (like spectra, etc) on all the DSOs, and remember that not every DSO has an exoplanet (the topic also covers younger stellar evolution). As for resources or websites https://www.soinc.org/astronomy_c
. You can go there and check out the newly updated webinar (Woot, Donna
!), in addition to other websites (apod is always a classic, but you might just want to google "[DSO name] + apod". Going to google images alone will get you many, but you might want to check some of the pictures you take because not all of them will be applicable to your DSO depending on how the google search stuff is. If there are more specific DSOs you are having trouble with, try to ask about those.
As for specific details, that's a bit of a general topic. Technically you don't have to know anything if the test writer decides not to write about exoplanets, but that would be silly and would make for a bad test/studying habits. How has rule reading been fairing, and are you confused by what is required as far as exoplanets go? A classic tip we on the website give is look at your DSOs and see what's important about them. For example, you might see a lot about debris disks, habitability, how exoplanets form, types of exoplanets, etc. So, any specific types of exoplanets or aspects of the rules you find hard to understand?
***Major Notes: The sponsor change did change the site resources is put up on, but if you check Astronomy on soinc.org you should be able to find all essential the resources posted without fail. The webinar also explains this all, so check that out.
