Thanks for the responses so far.
I am not sure if the seeing was obscuring the problem, but what I am 100% sure was that there was a night sometime in March which I remember so clearly because the seeing was so stable that I was looking at Antares at 400 and 500x and it looked like a mini-solar system with the bright Airy disc surrounded by a semi-bright first ring and then fainter rings with Antares B sitting on one of the fainter rings. I then looked at another random star with a 3mm Zoom and OMG, the Airy disc/Fresnel pattern was still as pretty. This is why I know it presented a non-astigmatic image before April.
Now since April, I was shocked when I saw the crosses at high power. I remember the only thing I changed was that I added a new finder mounting and replaced the red dot finder and also used a 6.3 reducer corrector-- which I since have removed, but the astigmatic images remain.
Now my wife and I travel a lot, and so maybe it got bumped along the way and that caused the issue?
As to what I have done so far since finding the issue, I have rotated the corrector although I did not take note of the change in orientation of the cross but it seemed not to do too much so I returned it to the original orientation. I have not yet checked the secondary and primary. I have also removed the corrector screws and just tightened them "finger tight" so to speak.
I am curious with the thing regarding the secondary housing-- how do I check this?
And yup, this is brand new, but I don't think I can get warranty because I imported it from the US to the Philippines, and I think the warranty from the US store only applies if I were in the US.
