That was very interesting to see how you went about adapting the larger Jaegers lens to the 3" Unitron tube. Great series of images of the work progress in the two threads of posts too. Mark

I had the Jaegertron out for the first time today for some solar observation. Only did white light with a glass inconel over the aperture filter and then with an APM solar wedge. Took it up about 120X with a 9.7mm Plossl ep and the solar wedge, up to just under 100X with the inconel filter and a vintage Royal Astro prism and 12.5mm Kellner ep. I was very pleased at how it performed. That is a pretty high magnification for solar with daytime turbulence. It presented absolutely lovely sharp and contrasty images at between 60 and 80X; nice granulation and lots of penumbral detail in the sunspots, lim darkening and bright white faculae. Even with a 26mm and ~47X the image still showed lots of detail.

Will do the moon, Jupiter and Saturn tonite.

The Jaegertron worked great last night on the Moon, Saturn, and Jupiter. Lots of detail, great contrast, a perfect velvety black sky as their backdrop. Went up to 200X with a 6mm vixen ortho. Some of the best views,of the moon I have ever had. Saturn, nice black inside the rings, Cassini's division easy at 100X. It was beautiful with a 9mm Unitron symmetrical yielding ~130X. Could see faint banding as well. Jupiter was first up. Jupiters's banding and Galilean moons nice in spite of being down in the soup. Nice color on the bands. After Jupiter it was on to Castor which it split nicely. The moon was the main feature, and Saturn rounded out the evening as the last entry. This scope as NO hint of CA what so ever. It would hold its own with the 3 inch Unitron though I didn't have them both set up. I guess I got one of the good Jaeger lenses. I am very pleased. :)

That is great. Mine is the best 80mm I have and my others are very good. Yes.. I can't see any color. An aperture ratio of nearly five does that with a well designed achromat. To me, it seems the Jaegers have a little better color correction than the other similar achros. My 6" F10 should have a good bit more color than my 5" F12 D&G but it is only very slight. They are both very well corrected.
