NGC 7635 is actually a rather small object, less than a quarter degree across. My imaging setup has a field of view of 4×2.72 degrees, and the object is a little above the center. The open cluster in the upper right quadrant is M52.
Below is a closer crop of the above image, showing the perfectly circular “bubble” in the center.
As counterpoint, here’s an exquisite image from the Hubble.
This image is a stack of about 30 10 minute exposures, taken over two nights.
