No check/comparison star? V0497 UMa

Community

What do you do if there is no check or comparison star? I was doing some DSLR photometry on V0497 UMa last night, and captured about 3 hours of data to see if I could capture the light curve. However, wen I check the images, I saw that there was no check or comparison stars. I then checked the finder chart, and found the same thing? What do you do in that case?

Thanks
