Hi all thanks for your comments.
Yes it is a full frame image.
Hyperstar is now also available for the Meade telescopes.
The DSI 111 has 1360 x 1024 pixel chip, fairly small compared to the Sbigs.
But with the Hyperstar lens at f1.8 almost the whole galaxy fits on the tiny chip. With my f3.3 focal reducer it would capture around half of it. I find for around $1000 Hyperstar gives me the ability to image wide field objects with my 11 inch celestron. The other benefit supposedly a 1 minute exposre at f1.8 is the equivalent of 32 minutes at f10, a big advantage.
So is my 40 minute f 1.8 image here is supposedly like a 21 hour exposure at f10? I don't know, but I do know that I can capture 10 x 1 minute exposures of the Horsehead or Orion nebula and get a great result that I would not get at f3.3 or f6.3 at 10 minutes.
