The purely FT answer ... by winding up mag and using focus ... you want a bit more mag than 25.
How much is that Falcon? I'd look around for second hand scopes. Try and stretch your budget and get as good as you can. It's no point just going for high mag. Some of the cheaper or mid priced scopes with high mag give poor picture quality. That's no good. I reckon you'll get a decent second hand FT scope for @ 200 - 250 quid. Put a wanted ad up for an old Custom Shop or similar ( or do you already have the Falcon 25x scope? ).
