Change the ball shaped 90 degree "diagonal" to a 1.25" mirror diagonal and 32mm plossl.

Total cost $12 + $20 if bought online from overseas.
Big improvement over the original stuff that came packaged "free" with the Astromaster.

Just make sure to avoid the powerseeker127 because it is bird-jones lens inside. It's something bad. If you slowly hunt for a proper parabolic newtonian it is possible to still fit inside the same budget or price.

The aliexpress photo show glued objective , so perhaps expect slightly more edge abberations than air-spaced.

If you were comparing the nexstar SE series , then the 4-5 vs 6-8 have different mount although they look similar.
The jump from 5 to 6 is not just the telescope bigger but also the mount.

^ That mount he have is powered by hand turning knobs.

Those 2 telescope you quoted are maksutov design , unsuitable for DSO astrophotography.

Weak mount weak tripod (relatively cheaper) limit your upgrade options when your scope or instrument get heavier in the future , later you end up buying twice ...
