on that night where I'd neglected my finder, I was using my 24mm Televue Pan as the lowest power, highest TFOV EP to do my searching. Crude, and not as effective as a dedicated finder, but it did the job, so I can't complain.
I haven't had the chance to properly road test the RDF that I have because the scope is currently with the dealer awaiting testing, and possible replacement. However, when I did get the chance to use the RDF (briefly) it was quite effective. More than enough to be getting on with for a 90mm scope.
No doubt, with practice and proper use of the finder, I'll get plenty more objects under my belt.
