Your choice for the Nikon 10-20mm is great! If you really want to be prepared and are short of funds, trade the new 35mm for a 55-300mm or 70-300mm for detail shots and compressed, distant shots. For night photography you do want a large aperture, but on a wide lens - 15 -24mm FX equivalent. Going to throw in another choice not yet mentioned. The new Tamron 10-24mm f4 with IS and weather-sealing. Longer range and better built than the excellent Nikon, but also more expensive. Stitching/blending is hit and miss and definitely time consuming in pp... Cheers, Peter S.
