Lookin' good.

I've done a lot of imaging with an Olympus OM-1 on my Questar and had some satisfaction.

When I changed to a Canon 20Da, I've not had the same result. Although the 20Da has a mirror lock-up, the shutter activation causes enough vibration to blur the image. Hopefully your set-up will work better.

Here's my first shot with the Questar at prime focus using my Canon 40d. (mirror lockup, ISO 200, 1/30 sec)

I have better luck using a Panasonic LX3 P&S digital camera in afocal mode. No mirror slap, much smaller camera footprint and weight. This was taken with my Q, using a Scopetronix 18mm EP, prime focus, ISO 200, 1/200 sec, un-driven....Barry

Great shots Ed and Barry.

Barry,
Is that hand-held? Or is there a way to mount the camera, if you don't mind me asking. I've the LX-5, and took some shots of the Venus transit through the eyepiece hand-held, but have never tried prime focus (by which, I assume you mean without the prism—since you are using an eyepiece). Could you share what is needed?

I've also got a big, heavy DSLR, but don't want to go there on the Questar.

Thanks, Brent

PS: Here's one quick and dirty hand-held shot of the Venus Transit. The air was extremely turbulent, so nothing is sharp. There was a storm blowing in.

Brent, that is not handheld. Here is a link to give you some tips. First you have to have the adapter tube for the LX-5; I have one too.

Thanks Barry. Where does one get such things as the adapter tube and eyepiece projection tube?

Also get the Richard Franiec cable release bracket for the Lx3/Lx5.
This is called Afocal projection. In the link are links where you can get the stuff, or use Google.....Barry
