secondary mirror far down the tube?

TS has a lightweight 6" f/4 newt on the shelf.
Complete assembly weight is stated between 4.4kg and 5.3kg, depending on which language you are viewing the model's page in.

I will probably order this one for AP on my EQ5 - thinking that the low weight of max 6kg will be okay for my tracking. The low cost of 600 NZD (460 AUD) including shipping and NZ GST certainly is okay for my wallet and leaves room for 7x50 binos.

What do you think what the benefits and disadvantages are of mounting the secondary mirror so far inside the tube?

Disadvantages wouldn't be turn offs for me because I've seen "example images" on the web and am really okay with what comes out of this tube.

But I'd like to understand this feature from a theoretical and practical point of view.

All input most welcome and much appreciated. Thanks
