Diagnoal upgrade for Celestron starsens explorer dx102az

[Guest]

Would this Teleskop-Express: Celestron 1,25" 90° diagonal prism for refractors and cassegrains be a good upgrade for the Celestron starsens explorer dx102az ? I've read the one that comes with the scope is very basic and bad.

If it's a good upgrade, how will I notice the upgrade?

Since you have a Celestron scope, I suggest you read the above and take a good look at the diagonal that came with your scope, before throwing your money about.  If you can find an extension tube, you can test the scope straight-thru without a diagonal.

My Celestron C8 came with an excellently performing prism diagonal. (#93653-A)
