Hey, Dalia and Antoine not sure if you have to deal with dew in Las Vegas but here in South Texas it never ends. So my question is where to place the heat bands on Newtonian Telescope. I see a lot of Youtube videos on Refractors and Cassegrain type tubes but nothing for the Newtonian's. Do you have any knowledge, insight or experience here? Thanks for any help.

Hello,
We never have to worry about dew here so we do not have any experience with that, but the heat band should be placed either at the very "end" of the optical tube, or on the dew shield itself if you have one (recommended).
Also, this post might shed some light if you have dew on the secondary mirror as well: https://stargazerslounge.com/topic/323378-really-bad-dew-on-secondary-newtonian-130pds-mirror-dew-shield-not-helping-help/
