I see Sirius B tonight!

After I collimate my C14 as accurate as I can, I aim it at Sirius,  change eyepiece to nagler 7mm, I see a dim star locate east, about 10" from Sirius. It separate clearly. To eliminate possible ghost glare, I move out of focus slightly. it disappear, refocus, it get back. I am pretty sure it is Sirius-B!

Congratulate myself!
