Nextseq500 output from bcl2fastq 2.20

After bcl2fastq the below is what my first two lines of R1 and R2 look like. Being new to Illumina data I don't think it looks right and wanted to confirm. Thank you

Format of the data looks fine.

First few reads generally have N's so I would not worry about that part. Hopefully rest of the data is of good quality.
