What if you have 2 Barlow lens, 2x and 3x, and have both stacked together with a 20mm eyepiece? Would that work?

Hi. I own a Celestron 100az Inpire Refractor telescope. It really brings tears to my eyes when, with the help of the skyportal app, I could see for my very eyes the astronomical bodies that I once thought I would only see in textbooks. So I opted to buy the Celestron accessory kit that comes with a 2x Barlow. However, upon equipping it between the diagonal and the scope itself (3x), I couldn’t seem to get it to focus on an object (it reaches the limit before it focuses). I was focusing on Sirius for that one bit. Any tips on how I can make it to focus better?

Good info,I would have never thought of putting one between the scope and 45 angle eyepiece holder. Cool going to try it.
