It turned out that the object can be photographed not only in July-August but also in August-September. The object is lower, but the sky is darker. Doubled the total integration time. Added 5 nights from August 30 to September 8. Exposures of 300s and 600s.

Yes, no, of course. I have trees below 10-15 degrees ;).
In early September, at 9-10 PM, its altitude is 16-18 degrees.
The object has a declination of -14, and at culmination, its altitude is about 21 degrees.

Hour angle is about 2 hours. So, in late August to early September, it's even better for imaging.

I checked the object's trajectory in Stellarium—at this altitude (15-18 degrees), it's only visible for a couple of hours, even less—roughly from 9 PM to 10:30 PM. By 11 PM, it's already down to 10 degrees. In short, not an easy target at 56° latitude. Respect.
