Hi All,

Thank you all for your responses and taking time to discuss. Well, in that case, I will get a Dobsonian 8" telescope. How do I find that is collimated?

I'm currently reading this article to understand what collimatation is and how to collimate a Dobsonian telescope.

Two scopes that I have in mind,

1. https://www.bintel.com.au/product/sk...v=6cc98ba2045f

2. https://www.bintel.com.au/product/sk...v=6cc98ba2045f

3. https://www.bintel.com.au/product/bi...v=6cc98ba2045f


The first two are Skywatcher brand and the third Bintel and I'm not sure which of these is bang for the buck.

The 1. comes with 2" Crayford Style Focuser with 1.25" adapter and Super 25 and 10 eyepieces. While the latter comes with 2" Focuser with 1.25" adapter and 1.25" Super 25mm and 10mm eyepieces. As suggested by Jeremy, the 3. is a 10" scope that seems to come with 2" and 1.25" eyepieces. I don't have a fair understanding of eyepiece specifications and the differences among the three here.

Thanks again.
