Anyone here using ptgui and can help me with my nadir blending..

i'm taking 2 nadir shots. 1 every 180 degrees
and when stitching with ptgui, it blends like it's only 1 nadir shot.
and i'm getting to much of the mounting bracket in the picture, and have to do to much photoshopping to get a perfect nadir..

i know it can be done. have seen nadir shots where you only see the tripod and a level bubble on each side..

if u dont understand what i mean look at this link..


i want the right side of the nn3 to be like the left side..
