Look Up Angle to shot was studied by Meade 12inch + ASi290Mc for moon age 12.6 at Arisrtarchus. Also Camera was compared( Asi290Mc vs QYH5LII MM).
1st is Best shot of Aristarchus,it was 21:00 on Sep03 2017 which means Moon location was almost crossing Meridian.( as well known by theory for stable image)
Picture was
Prior to the above shot ,on 18:30 low look up angle shot was taken for comparison.
(included Camera comparison under FireCapture V2.5)
Conclusion looks high angle is better.
Of course Seeing and weather condition needs to be satisfied. Some question is
still remained for angle comparison because seeing was not same at those time ....
Need to continue this study to get clear result.
BTW, camera comparison was very clear that ASi290Mc is better.
Asi290MM would be better to compare....in the future hope near term....
