evostar 80ed ds questions

[M40]

Well I have ordered the new toy, an Evostar 80 ED DS PRO, no idea when it will land so in the meantime, I have been looking at the telescope and trying to get some information together. So if you kind people in the know could advise please...

Is the star diagonal included in order to achieve the focal length or can the focal length be achieved with the focuser alone?

With the standard focuser, what is the length of the OTA with the focuser wound fully in and fully out? Doesn't need to be exact, to the nearest 0.5mm will do.... 🤦‍♂️

If anybody has fitted the Baader steeltrack fitted, what is the OTA length with again focuser fully in and fully out please.

Finally, just trying to check my math, with the 0.85x reducer, I make it that the reducer should be fitted about 9.7mm from the full focal length, does that sound right?

Many thanks in advance for any help

The reducer should be fitted 55mm from the camera sensor, that’s the sort of normal way to work it out 🤷

Thanks for that 👍 looks like I have the spacers necessary to achieve that bit, I was also looking at spacers between focuser and reducer to remove the need for the diagonal. With such long deliveries at the moment I was trying to minimise the wait, I do know that I will always need just one more adapter.......
