This main stars in the 'Northern Crown' form an obvious arc, wherein, Alpha to Epsilon are appear close together in the sky. Indeed, it is probably only in the 'Southern Crown' where the first five stars appear more closely associated.
Corona Borealis is somewhat of a "Moonlight Constellation". There are no DSOs to view here and indeed the faintest star here is normally only at Mag 10.
Below are the subjects in Corona Borealis that I wish to view:-
The Main Stars:
Alpha Coronae Borealis. A binary star with a period of around 17 days. An unusual star in the sense of being hydrogen deficient. Alpha is thought to have been two-white-drawf stars that have previously merged.

Beta Coronae Borealis. Another binary star with a 10 year period and a seperation of 0.25 arc seconds, which is way-too-small a gap for my equipement to resolve.

Gamma Coronae Borealis. This consellation is full on binaries! Gamma has a 90 year period and a separation of less than 1 arc second.
https://en.wikipedia.org/wiki/Gamma_Coronae_Borealis
Delta Coronae Borealis. This star is in the process of transitioning to be a giant. Delta is also known for having magenitic variations similiar to those of our Sun.

Epsilon Coronae Borealis. Epsilon is an orange giant with an orange dwarf companion, whose orbit takes 900 years.

Other objects of interest:
T Coronae Borealis (The Blaze Star). This famous star has featured two seperate nova outbursts some 80 years appart. The last was in 1946, so another could be due any time now! The star can be seen shining at 10th magnitude in its normally quiet state. It may go supernova at some stage and if so, it could appear with the brightness of a crescent Moon.

Zeta Coronae Borealis. An easy double for small telescopes.

Sigma Coronae Borealis. Another fine double where the main star is similiar to our Sun.

Nu Coronae Borealis. A double said to be visible to the unaided eye. The two components are unrelated and are approximately 60 lightyears from each other.

https://en.wikipedia.org/wiki/Nu2_Coronae_Borealis
R Coronae Borealis. (A reverse nova). This star is normally around magnitude 6, but can drop to around mag 15.
