Need help with eyepieces

[Joyello]

Hello!

So, I am probably going to buy these pieces for astrophotography:

- Celestron onyx 80edf (used!) for under 400€

- EQ6 mount (used) for ~750€

- Skywatcher Startravel 80 (new) as a guiding scope for 100€

- Orion starshoot autoguider (new) for 300€

- Camera (don't know which still, but I am going for a used canon)

Now, I am struggling to understand which eyepieces I should add before I make the order.

I am going to need a flat field lens for the refractor (~200€), but what else?

Thanks everyone!

Sorry I can't edit my first post.

Where are you going to put the eyepieces?
If they are to use when not imaging then something like an 8mm and a 12mm then a wide one at 25mm.

Assuming new and I will use TS as a source the sizes above from their TS NED selection, or the 7mm, 12mm and 25mm from the X-Cel range.

Those 3 should manage most aspects.

Okay thanks!

Do I need anything else for imaging?

I don't get involved in imaging myself but I don't believe you've mentioned your editing software.

That's why I need your help.

Does it matter which software I am going to use? I've used DSS before through my university..
