The important issue is the 'long distance' use. Are you shooting targets at 100 or 300 yds ? I have an older Celestron Cavalry model 25-75x70 that I can see 22/223 bullet holes at 175 yds on white paper, black target rings are not as visible. I use 3/4" sticky-dots from dollar store for POA on poster board - also Dollar store, 2/$1.25. For short range I space at ca 4-6", for 175 I space ca 8-12" depending on the rifle.
PS - The Celestron was ca $150 20 years ago. There are similar ones on amazon now from ca $100 Up. Celestron is a mfr of home Astronomical scopes as well as spotters. Reviews on CT page here - http s://www.canadiantire.ca/en/pdp/waterproof-spotting-scope-25-75-x-70-0750502p.html#srp - Review #6 by 'sotopanna' is comprrehensive and knowledgeable. Some negative reviews are obviously 'uninformed users'.
And I use a 45* scope with a full-size photog tripod, not a bench mount straight scope.
