well for me 15x70 wins over 10x50 ,for it shows much more . may be my 10x50 was not a good piece , so i under rate them

well i do have a 10x50 low end bino ( which was misaligned , since i ordered them online , i did not return them ) but recently i purchased a celestron skymaster 15x70 . i find it way better than previous . it is optically well aligned . it is bit heavy but could be hand held for some time . but the main thing is it shows u a lot more . if u can hold it steadier by some way ( as i do not own a tripod ) , it is a treat . when u are used to see stars up to magnitude uo to 6 or 6.5 ( which my precious faulty one showed ) , and now u see up to 9.5 or so , u really get excited . it also shows more DSO . i still think , optically my new one is not perfect . but one thing ,a close to optically perfect 15x70 is obviously better than its 10x50 counterparts as far as stargazing is concerned .
