Not sure if this is a repost since I've only been back for a day, but Surplus Shed has been selling some more old Jaegers lenses for bargain prices. I just picked-up a few achromatic objectives with cells, a 6" f/10 and 6" f/15, as well as their legendary 5" f/5 doublet with cell. Just for kicks I also bought an 88mm f/2.8 doublet with cell. Anyone who doubts what a large doublet can show you should take a peek through Steve's D&G or Ziggy's Clark. Get them while you can. http://www.surplusshed.com/
Chuck,
Welcome back, the 5" F5 caught my eye too. I have the 6" version but did build a 5" tube assembly with the Jaegers a few years back. It is a great lens at a great price, add a V-block or Minus Violet filter and the chromatic aberration is greatly reduced. Erik Not sure if this is a repost since I've only been back for a day, but

Thanks Erik, good to be back. For what I use these things for, the filter isn't even necessary. Just sweeping the Milky Way, clusters, etc. No moon or planetary targets for the f/5. A fast doublet would be a good choice for narrowband imaging, as well. Any uncorrected color isn't a concern. Like using a singlet for H-a solar observing. I built a few of the 5" for the club about what, 35 years ago? I wonder what happened to them. On 7/26/11, erikhansen@thebluezone.net <erikhansen@thebluezone.net> wrote:

Neat. Looks like the seeing was getting better just as you ended your session. On 7/26/11, David Rankin <David@rankinstudio.com> wrote:

Damn Surplus Shed. I just bought a Jaegers 6" f/5 objective and another cell to go with it. Good thing the garden is in high-gear or I'd starve this month. ;- )
