Hi Dave, and welcome to CN! The 90 is an awesome little scope by all accounts (I haven't had the pleasure of using one myself, but judging from some of the photos and reports I've seen here, it's a marvelous instrument!)
I'm not sure what kind of finder you have on the 90EC, although it sounds like you might have a small optical finder. I know a lot of folks wind up putting a Telrad or similar "dot" style finder to replace or augment their optical finders, so that may be an option for you.
Looking forward to hearing more as you rediscover your hobby! Clear skies!
