Hi, Sorry for the confusing topic there.
I have a Skywatcher Esprit 150, it comes standard with a Field Flattener.
The other day i disassembled it to clean the two glass mirrors as the inside had gotten a bit moisture and dust on them.
Simple enough task really, But in my disassemble, i didn't take into account on how easy everything would come apart resulting in me loosing the correct ordination on which way around the two mirror come out, weather they were concaved or convex.

I know which glass went where, as in which one was the closest to the camera end and which one was at the other end, just not sure which way around they both were suppose to go, either concave ) or convex (
I was hoping someone here might be able to advise me if they have something similar.
So the lens closest to the camera, dose it face the camera concave ) or convex ( and the same for the second one, dose it face the camera concave ) or convex (
I hope that all makes sense,
Any information would be appreciated.
Cheers.

I can’t be of any help however, I’m interested in your assessment of the 150, which is a very large Apo.

So far the Esprit 150 is performing very well, both for visual and imaging, just need a lot more time to practice the imaging side of things though.

I may have found my answer though, looks like both lens need to be in the same orientation and installed so they look like this: ( ( with the camera pointing at the convex part of the element
