Date for IC 4628

That is a great image Louie.

I have been trying to find the date when IC 4628 was first imaged by E E Barnard. It seems that it was before 12 June 1895.

Here is one of his first images. It was taken with the 6" Crocker telescope at the Lick Observatory near San Francisco.

Barnard imaged it again 10 years later on 21 June 1905 with the 10" Bruce telescope from Mt Wilson near Los Angeles.
It is plate/region 16 on this page.
