This october three astronomers (I and two my colleagues) trekked in Everest area - for 15 days we did Kathmandu->Lukla - Phakding - Namche Bazaar - Tengboche - Chukhung (Chukhung Ri)-Kongma La (pass) - Lobuche - Gorakshep (Kala Patar) - Dzhongla - Cho La (pass) - Dragnag - Gokyo (Gokyo Ri, fifth lake Cho Oyu) - Renjo La (pass) -Molerung - Namche Bazaar - Lukla → Kathmandu.
No problem, except one of my colleague fainted while climbing to Kala Patar, but descent to Gorakshep helped him so much, so he even ate omlet !
After trek we spent lovely 4 days in Kathmandu walking around, relaxing and shopping.
I started to publish my pictures to my flickr page.
