Nuevo skylight

I have recently bought a 2014 Nuevo.  I feel a right idiot because I cannot see how the rear skylight (the small one by the rear door) opens and closes.   There is a little catch but no other handle, like on earlier models, or other visible mechanism.  Help!

I would guess you release the catch and give it a shove - carefully as the skylight may have stuck to the rubber seal.

A photo would help.

Twist the catch and push up  ,the problem is auto sleeper us very poor seals that stick to the skylight. ,I run a thin credit car between the seal and sky light  to break the seal ,the large wind up skylights also stick and break the flimsy wind up mechanism  , I support the skylight with other hand while winding  ,I have had two break in 12 months  ,warranty, I also dislike the water fill system  much prefer old fashioned hose pipe,

Not sure I understand the hosepipe comment.
I have a 2016 Nuevo which I am able to fill with a hosepipe.

Is a 2014 Model different?
