Apologies if this isn't the right section to post, but it's been a while since I did any observing/photography with my WO Megrez 72. Last night I got everyhing set up and realized I hadn't put a new battery in for the digital display gauge. Rather foolishly I tried changing it in the dark. Whilst taking the cover off I was trying to keep hold so as not to lose the two screws, but heard something drop 😱. I doubt it was the screw as it's very small and I can't recall if there was anything between cover and battery. Long and the short of it is, if I can't find the screw does anyone know what size would be a suitable replacement? Also, if anyone also has a digital display gauge on their 'scope, could you confirm whether there's anythinh between cover and battery?
Thanks in advance.
