Still wondering if this solution would work, and not being able to go to a store (not nearby) to test it myself due to the confinement, I’m giving this thread a small bump
Any experience with trying to fit a scope inside this backback is welcome! (If e.g. someone has a 80-85mm scope that fits inside, my 65 will probably too.)
I've got the bag but I don'have that scope. The side pockets are approx 35cm top to bottom. Given the angled eyepiece you might just get it in non-vertical with the objective lens at the top. If you were prepared to split the body and the eyepiece then I'd guess it would fit OK. FWIW a Nikon P1000 camera fits comfortably.
Lockdown is easing so a shop visit should be possible. Given the cost of the bag and your requirements I think you really have to try before you buy.
Other comments for anyone considering this backpack:
+ve
Very well made
Well designed and thought out
Comfortable (have walked 15Km without issue)
Good space (P1000 one side, cag, drink and lunch the other)
Probably waterproof
-ve
Cost
Neutral (be aware of)
Scope is head height or above - not stealthy
Velcro leg fixing only just goes round top clamp on 4-section tripod
Antisocial if carrying with legs fully extended (but easy enough to raise/lower L&R legs whilst carrying.
Given the price and idiosyncracies . . Try before you buy!
