Komrong is along the same line as my suggestion, I judged the height differential wrong. The peak is Annapurna III.
It's roughly in the same area, but according to my map, if you were heading towards Ghandruk from Tadapani, you would need to take a sharp turn to the left about halfway along the track, and head north to get to Komrong which is about the same distance from Tadapani as Ghandruk is from Tadapani.
Are you sure the peak is Annapurna III? That peak looks on the map to be more than twice the distance from Komrong as Annapurna South, as the crow flies, or as the light travels. The focal length used for the shot was 82mm on the D7000, which makes it 123mm in full-frame terms. Annapurna South seems the more likely candidate.
Using a ruler on my map which has a scale of 1:50,000, I measure the distance between Komrong and Annapurna South as 250mm, and the distance to Annapurna III as 550mm.
That translates to a distance of 12.5 km for Annapurna South as opposed to 27.5 km for Annapurna III (those crows sure have an easy time
The question is, would an average quality zoom, at a focal length which is far from being its sharpest, be able to deliver the detail as seen in attached 100% crop, from a distance of 27.5Km?
I do need some luck, as my right hip is getting worse from osteoarthritis, left one was fixed already in last May. We'll see, slow walking, plenty of photographing...
If you have oseoarthritis, the exercise in Nepal should be very beneficial as long as you walk within your fitness level
. If I were you, I'd hire both a guide and a porter. If you get into trouble, or find the going a bit arduous, your guide can offer a steadying hand, which would be more difficult for the porter to do because of his heavy load.
There were times during my trek to the ABC in April 2011, whilst climbing about a thousand irregular stone steps for the second time in a day, I'd hand over my heaviest camera to my Guide to carry, who would walk behind me or at my side, and would quickly hand me my camera on request whenever I felt the need to use that heavy 14-24/2.8 lens with D700.
Take care, and prepare yourself for the trip by walking up a few hills in Finland, or wherever you are, before you go to Nepal.
