Hi Sharmila,
Good call on not buying a cheap telescope.
As far as budget goes, I think you can get an 8" Dob for approximately 40K, firsthand.
Another option is to attend a star party, where you can get to look through a few scopes. The season is almost upon us, which is a good thing.
Do note that BAS seems to be more active on the WhatsApp group than the mailing list. (I'm not on WhatsApp, so my information is possibly inaccurate).
Someone from the group should be able to help you with an invite if you're interested in joining the WhatsApp group.
Best,
Karthik.
