+1 for ‘I do that too’. (Including not recognizing the reminder prompt).
I liked the idea about doing what the pilots do but my mind immediately raced to something that I’ve seen in the movies. Specifically it is the big red strap attached to some critical component (generally, a warhead arming device). As we all know, they don’t let the airplane take off until all the straps have been removed.
My thought is to attach a big flowing nuisance ribbon to the red dot finder. It should be easy enough to brush out of my way while I complete the alignment but enough of an obstacle that I’d make sure to remove it for regular telescope use. (Now if I can only remember to go buy some ribbon LOL)
