Which is better for planets and the Moon?

The DX 5" SCT. Its f/10 optics and 125x 10mm eyepiece give high contrast on Saturn's rings and the lunar terminator, and the slow-motion controls keep the target centered. The 130AZ works too but needs more hand-tracking at high power.

Which is better for galaxies and star clusters?

The DX 130AZ. Its f/5 field frames large objects like the Pleiades and Andromeda, and the 130mm mirror gathers slightly more light than the 125mm SCT.

Is the DX 5" SCT worth the extra $90?

Yes if portability and steady tracking matter to you. At $589.99 at Adorama versus $499.95 at Walmart as of November 6, 2026, you pay for a 5 lb sealed tube, slow-motion controls and an erect-image diagonal.

Which is easier to carry and set up?

The DX 5" SCT. Its kit weighs 14.6 lb with a 13" tube, against 18 lb and a long open tube for the 130AZ.

Do either need collimation?

The 130AZ does, now and then, and it takes a few minutes. The SCT's sealed tube rarely needs it.

Do both use the same StarSense app?

Yes. Both use the StarSense Explorer app and phone dock to find objects, and neither needs batteries or motors for pointing.
