Richard,
Iıve used the Lumicon 80mm Super Finder RACI on my past 20² Starmaster.
Itıs a really good finder, and fairly lightweight for its size. Right now I
still have a Stellarvue F60 (10x60) RACI finder off of my past 18²
Starmaster. I will probably move back to a 80mm finder when I get my 24²
Starmaster this summer. It will be the Lumicon (again) or maybe the
Stellarvue 80mm RACI. There is a 1 mag. stellar gain between the 60mm and
80mm finders, but you lose the fov. The F60 provides me with 5 deg. fov and
the 80mm finder only provides 3 deg. Itıs what youıre comfortable with
using. I do like RACI over straight through finders - your neck will thank
you for it. The weight of a finder is also an issue. If total finder
weight is an issue, with adding a 80mm finder, exchange the heavier Telrad
with a lighter-weight red-dot type of finder (Orion) to accompany the 80mm
optical finder. The 80mm finder goes to mag 11, matching my Millennium Star
Atlas. I like the idea of a combo finder system: a small 1x finder (red dot
type) alongside a 3 degree fov 80mm optical finder. This is a setup for
quick manual deep sky object finding quick object finding.

Subject: [TAC] 70 OR 80 MM CORECT IMAGE FINDER
I'm seriously considering getting a 70 or 80 mm correct image finder,
straight through or right angle.? Suggestions or recommendations welcome.
Thanks,
Richard
