 I observed Comet C/2022 E3 and found it brighter than I read on various sites. Probably those values were referred to the central part of the comet (which however is very small and condensed).
The great difficulty in giving a good magnitude value is due to the fact of being in a very dense area of the Milky Way. I worked miracles to try to eliminate as much as possible the stars that were very close to the comet (used various methodologies and programs and also changed the rays for the dimensions). Even in this way, the stars remained the same even if much less invasive. However using about 12 different ways (to eliminate the stars especially in those very small spaces where the comet was with a few faint stars around) for an average diameter of 15" (a middle ground between 10 and 12 pixels in diameter) the photometric values (used a clear filter) were all between 13.9 and 14.1. 
I would say very likely the value of 14.0.
The tail (faint) was even more complicated to understand where it ended. It also looks slightly curved. The data (not very precise) gives me a length of 42" in PA206°.
I attach the two images. One is the median/sum of 30x90s with Frasso Sabino's reduced cassegrain (scale 1".34/pixel, perfectly north up and east to the left) with a field of 22'.8x28'.5. .I hope you can find it.....
