Hi Debbie, Thanks! I'm no expert, but the reason I used a focal reducer is that it reduces my exposure time and gives more arc seconds per chip -- that is, a wider field of view. So I think yes, it should be easier with a shorter focal length. Best wishes, Joe --- On Fri, 9/17/10, Debbie <astrodeb@beyondbb.com> wrote:

Isn't it true that it is easier to image with shorter focal lengths? I may try piggy-back imaging next year with a Canon Xsi live-view focus camera. At some point I may try PHD autoguiding if I can find a guider that works with Vista 64-bit OS. It seems that there are a lot a technical hoops to jump through when it comes to astrophotography.
