The Dagor Doppelanastigmat was designed 1892 by Von Hoegh for Goerz. 180mm is for 13/18 and 240mm for 18/24. Angel is 70°- 90°. It depends on stop down. Dagor has 6 lenses in 2 cemented groups a`3 lenses. That means 4 glas/air plains only or a minimum of inner reflections.
It is possible to use the backgroup alone if you stop it down to get a softer 360mm lens.
In my opinion Dagor is a good lense BUT due to hype much to expensive. If you mean better = sharper look for the much later designed "simple " Schneider Angulon 165mm. If you stopp it down to f22 it is difficult to see the differenze to the heavy and more expensive follower Super-Angulon. With the Angulon you have 3 lenses (front, back or both together).
Thanks for the info rhineroo, mine was 20€ shutterless. I still need to try it on 8x10.
Good catch, Ramiro. I wouldn't think twice for 20€ if it is in reasonable condition. I have a good 6.8/210mm (1913) and a poor, battered up 7.7/240mm (1898) and love them. These are remarkable lenses, capable of stunning image quality and a beautiful oof rendition. But I agree that there is a lot of hype about them, pushing the prices to the unreasonable. It's like with the Heliars (in my opinion).
The 180mm barely can cover 8x10 when stopped down beyond f32 (Goerz scale 96) but it was meant for 5x7. A practical word of warning: Dagors suffer a slight focus shift when stopped down, so be aware.
And here is a very good web site on Dagors with a lot of interesting infos.
Enjoy your little gem,
Peter

Originally shot on my Dslr for Alamy, deciding that it need the LF treatment (what doesn't) it is still a bit of a work in progress. Once happy with it I'll post it a bit bigger....in case you're wondering its a handful of kebab skewers shot from above....and its the sort of shot that you can play with for hours and still not be happy with!

They're fun exercises in building a composition instead of using found ones, they teach a lot about lighting and contrast. they can be representative of an idea or an emotion, it gives you something to shoot when the weather's crappy outside and they have a bit of a zen component for me. I shoot still life images for art sales, not so much for stock. Landscapes and florals sell much better, though.
