A 350,000 x 175,000 Panorama of the Night Sky. That's over 100feet at 300dpi

Making a huge Panorama of the night sky as visible to me ie. 20-30*North of Equator so 20-30* of South Polar Region won't b visible(that's OK, I'll need to go to South America or Australia)

So a 350,000 Pixel wide Panorama will print at 300dpi photo of more than 1000 inches! Over 100Feet.

Woppy.

Using PTGUI Photo Stitching app, Canon 650D many lens..

1. Canon EF 90-300mm will give a field of view of 12-14 degrees(the long side of 4:3) at 90mm and just 5degrees FoV at full Zoom 300mm (effective zoom is 480mm x1.6 camera)

2. 18-55mm Canon gives an FoV of 72 at 18mm on my camera and 20-24 degrees at 55mm 

3. 10-24mm Tamaron (3.5-4.5) Ultra wide distorts too much but I can shoot the entire night sky in just 1-2 frames/setups. I will do one when I am at. Dark place, I think I have shot some with 10mm (16mm on my camera). At 24mm I get an FoV of  30 degrees. Which is I think the ideal for a High Resolution Panorama thats more than a GigaPixel of useable image!

An early example of ultra Wide 10mm (16mm) photographs and the Bootes is 24mm (35mm)
