      Hi Sal,

      I posted my review of the GTF102 last year.  It's very good for astroimaging but I have been out only once all Winter here in Chicago.  I wish I could have done some more. I have severe light pollution, and just got an Astonomik CLS Clip filter for my Canon 60D DSLR, 

      What questions do you have for me?  Did you see my review?

      If you are looking for a wider field of view, then the GT102 with the WO FLAT6A would be the better option.

      Timm
