Quite interesting, John.
Well, below is a link to the Jason 313's instruction manual. On the last two pages of this PDF document, it explains the workings and collimation of the SLR Finder. If your scope has the bracketed stand-alone type finder, I do not understand why the designation is labeled on the box.

Hi Al,
You probably don't have a PDF reader installed. You can download and install AcroReader from this link => AcroReader Download Site . If you do not want the McAfee software, just uncheck it. Once AcroReader is installed, you can click on the previous link again and it should open.

After some more testing, I'm pretty sure my Jason 60mm beats my Sears 80mm - both in FOV and image clarity. The Jason TFOV is 1.25°; the Sears measures in at 0.97°. The Pleiades, the Double Cluster, and Jupiter all looked a little better/sharper in the Jason scope, and the Ring Nebula was just as bright in the Jason. I split Epsilon Lyrae in both, and I was a little better with the split in the Jason scope. The Jason also seems to "snap" to focus better on most objects. Not bad at all...

Congratulations aa5te! 
I always looked forward to other amateurs conveying the true attributes of the underrated Jason 313, and you are now a proponent to that belief. But, I am quite surprised it whipped up on the Sears 80mm a bit! What eyepieces did you use?

I used the same 0.965" to 1.25" diagonal adapter with these eyepieces/barlow:
Zhumell 32mm Plossl
Zhumell 8-24mm zoom
Meade 9.7mm Super Plossl
Zhumell 2x barlow
and I also used the Circle K 0.965" 7.5-22.5mm zoom
What really surprised me is that M57 in the Jason seemed every bit as bright as it did in the Sears (60mm vs. 80mm).
One negative though - the SLR finder on the Jason is dimmer and harder to use that the attached finder on the Sears (it is aligned, though).

 I recieved the scope in allmost mint condition and could have swore the pictures on ebay listing showed telescope with seperate finder. The one I got is exactly like you said a SLR should be. With the flip focuser...nice scope and mount with all accesary's. Sorry for confusion but seller must have posted wrong pictures then changed them later i guess. thanks,john

Hello again. Well I finally have my new camera and I took some pics this morning of my Jason telescope.
Right after i purchased the Jason it was cloudy almost every night for a few weeks. I was able to do some viewing with it recently though and I must say I like the telescope very much.
First light was very good. I observed the Moon, Jupiter, Pleiades, Cassiopeia areas on interest, and Orion. The telescope performed very well. Stars are very crisp points of light going to the edge of the field of view. I thought the stock eyepieces performed very good. The moon looked great as I could see peaks of mountains while taking advantage of the waning cycle. Looking into the craters depths was not a problem either on the edge of the shadows. I was surprised that I had pretty good seeing at 227 magnification. Though the image was washed washed over a bit I could still make out what I was looking at with definite detail of craters and peaks at the edge of the terminator. The mount was a little nervous at this magnification but I was smiling the whole time.
Jupiter looked very crisp and viewing the planets detail was not a problem. I was not able to make out the great red spot though.
Well here are some pictures of my scope that has been in a box since 1982.

Wow man, that scope is in excellent shape. Thanks for those pics. I really like my 313 a lot.
