Where can I find the binary structure of an X.509 v3 certificate?

Question

TLS

I am reading RFC 3280 ( https://tools.ietf.org/html/rfc3280#section-4 ), but apparently I am missing something and I cannot correctly understand the structure of the certificate.
For RFC 4346, there is a good article on the wiki where all fields are clearly visible ( https://en.wikipedia.org/wiki/Transport_Layer_Secu... ), is there a certificate similar for X.509 v3?

I studied the output of WireShark, but for some reason it misses some bits in the certificate, apparently considering them too obvious and self-explanatory ...

The issue was resolved by using the command program to work with X509 certificates from OpenSSL: openssl x509 -in certificate.der - inform der -text -noout

https://www.openssl.org/docs/apps/asn1parse.html - This thing can return offsets, field types and values. Or maybe not, try it.
