Unscientific simple comparison with phone camera on auto + 5 second timer , no dslr.
Non-tracking mount , no cooldown for scopes , no zenith.
Celestron Astromaster 102az achromat , 660mm focal length
SkyWatcher ed100 apo , 900mm FL
SkyWatcher 127 Maksutov , 1540mm FL with 1.25" mirror diagonal
The 102mm F6.5 achromat (Omni/StarSenseExplorer/PopSci) is very common in USA these recent few years for USD $199 with tripod.
Maksutov127 is a popular compact scope since around 2003 , my set is nearly 10year old with lower mirror reflectivity % as it degrade slowly every year.

Moon attempt #1
Phone camera doesn't sharp focus away from center , bigger maksutov image at disadvantage as closer to outer edge.

ED100 and Maksutov127 used same 25mm eyepiece bundled free with ed100, eyepiece causes blue colour around the edge of Moon.
Maksutov unfair advantage by flock modification at primary and secondary baffles to improve contrast over normal factory set.
Green tinge due to phone camera coating when phone not perfectly center aligned as Moon drift across.
Moon attempt #2 possible thin clouds
15mm eyepiece , phone camera confused by small bright surface on 102achro
