not with 125 aperture and 152 magnification. his image gives no single normal band on the planet disk. it's not OK.
for me there's not only aberrations but also some kind of pathological unfocuse.
c'mon. altitude can't affect so extremely the image, and if it were atmosphere we sometimes could see details and the image were shaking
such image can be also the result of extreme impurity of optical surfaces, that's why important to see the photos of instrument
I am not sure what you are talking about but some of the particulars are wrong. It is a 127mm scope, not a 125. I see no mention of 152x, since it has ~1250mm focal length and a 10mm eyepiece and 2x Barlow, the magnification would likely be ~125x or the 250x originally stated.
Low altitude with accompanying terrible seeing can indeed wreck the image badly, especially as experienced by a novice observer. You seem to be referring only to the video taken through the eyepiece at 250x (which is preposterously high for the conditions and aperture.) The other image later (magnification unstated) shows several belts and is likely closer to actual focus. This sort of unprocessed video is usually a very poor representation of the visual image, presenting much less detail than what the eye can see.
At any rate, the scope is not collimated based on the description and what I can see in the images so far. Like I said, I have seen a 127 Mak image wrecked by poor collimation, as received by from the factory. Until the collimation is addressed, we have no idea what sort of image the scope can put up. Best to start with the things that can be addressed, and work from there.
Declaring such a scope unsalvageable and suggesting "trash it and buy a new instead of trying to fix" as you did is unhelpful bad advice. It is downright irresponsible to tell a novice something like that, before they have even done any troubleshooting. Jumping to wild and unsupported conclusions is not troubleshooting.
Photos of the instrument, might help, but only if there is something glaringly wrong with the OTA that the OP has not told us about.
