If i use visualization mediation will the nimatta still appear?

I'm having trouble truly understanding nimattas. I use visualization for my jhana mediation. It's what focus my mind best and allowed me to almost enter jhana. But if i do visualize, will the nimatta still appear? How would i recognise it? And once it appear do i move off my object to it? Also i read this passage explaining what a nimtta means in the modern day. I wish to know does this do a great job explaining it. > Now certainly it is true that if you become VERY concentrated you might see an image that looks like "a star or a cluster of gems" or "chariot wheel or the moon's disk," etc. And it is also true that you can with sufficient concentration absorb into that experience so deeply that you no longer hear sounds, or are aware of your body, or are even aware of the passage of time. This is not what is described in the suttas; however, this is indeed what the later commentaries mean when they use the word "nimitta."
