Warships don't have portholes or observation decks. They'd be weaknesses in the hull.
But other personnel transports might, so may the stations and yards where the ships are being constructed. Whether you can see any useful constellations from inside the Refuge System's dust cloud is up for discussion. Given that medium- and long-range observations failed to see an inhabitable planet there at all, it's not impossible, but planets are much more difficult to see than stars.
As for captured images, I'm sure the same OpSec procedures that keep the navigation databases clean would apply to any other data storage carried by anyone. You don't bring any un-approved mass storage device with you and you're arrested if you try to leave with something that wasn't issued to you. What was issued to you is subject to censorship, the same way that sending emails aboard a warship would be.
You can't remove someone's knowledge (in the HV), but you can prevent them from taking high-fidelity data with them. The most that anyone not in the Top Brass should know is that:
a) it takes about a week to travel from the far terminus of the wormhole
b) the near terminus of the wormhole is a month's travel from Haven
c) the system is surrounded by a dust cloud
d) it's a binary star system with the bigger partner being a bright A-class star
e) there are five asteroid belts
f) the system has a native human population descended from a lost colony ship
No one but navigators and Top Brass need to know that the far terminus is the Calvin System.
The problem is that the native population is being educated and is working on the yards, along with the temporary expats, and those will know their history. They kept the Dark Fall saga alive for nearly 1500 years, and they must all know now that they are the descendants of the Calvin's Hope colony ship. It'll be impossible to contain that datum.
And that's not even considering Pritchart's promise to the native Sanctuarians that they deserve to be public in the Galaxy and have the freedom of travel, same as any other citizen of the Republic of Haven.
