from Commercial through self-built. In a section on converting Farm Silo Domes to Astronomical Domes I need a few photos of converted Silo Domes. These are hard to find since its not an easy job to slice through the silo dome to create a slot door section (they usually fall apart). I know there are some out there converted by crafty individuals. If you would like your observatory in the new book please submit a few images to me. I will give you acknowledgement under Acknowledgements and credit under the photo. I'm surprised that in your Observatory books list
you have not included mine - it was popular all through the USA and Europe, sold exceedingly well.
