Hi all,
This is my first attempt using my new f1.8 Hyperstar lens with my Celestron GPS11 and Meade DSIc.

It's quite incredible to be able to get such a detailed one shot RGB image of a low mag object at 20x15 seconds (5 minutes) exposure with a $500 camera.
Seeing was 7 out of 10.

If you look carefully I even managed to capture the outer secondary ring.

See more of my images at our Western Sydney Amateur Astronomy club new web site http://wsaag.org

Regards
Gerry

Nice image Gerry, I've been waiting to see an image from the Hyperstar and it certainly looks like it's going to be a winner.

Cheers

so was that fun to get? Nice image, stars a little bloated but that could just be the camera.

Thanks guys

Yes Leon that was the lens that replaced the seconadry mirror on the gps11.
Very weird to hang a camera off the corrector plate end.

The bloated stars seem to be a DSI trait. I have to get me a decent imager soon. Maybe a Starlight Express svx9 or one of the new breed hitting the market.

f1.8 is amazingly fast - and the results show. Was this taken at the Linden dark sky site?
