Anyway, I got a couple of observatories from Ajay Talwar. You can see the updated spreadsheet here.
- Sampuranand Telescope, ARIES, Nainital.
- Mt. Abu Observatory, Gurushikhar.
Thanks for the links Ajay! I don't know whether the telescope @ DU qualifies because I'm looking at telescopes of the observatory kind. I know there are many amateurs all over the country with beautiful telescopes but I'm not sure how I'd go to every place with a telescope. Perhaps, that's for another tour - The Amateur Telescopes of India tour?
