I don't sell any of these nor do I receive any remuneration if you buy them, and I have not personally reviewed all of them, they are listed here to give you perspective
Introduction
one of the joys of camping especially on a warmer night with clear skies in summer is the ability to observe the night sky from your warm bed
of course the best skies in Australia are in March-Oct when the centre of the Milky Way is visible at night but these will be cold nights
the visibility of stars through mesh does also depend on the type and color of the mesh
best viewing of meteors (shooting stars) is after midnight which is usually a time when mosquitoes are less bothersome and thus a clear view without obstruction by mesh or PVC is more an option if available
best viewing of deep sky objects such as comets, nebulae and star clusters is with a wide aperture binocular (eg 10×50) but these work best without mesh or PVC obstruction
there are a range of options:
most swags and hammocks allow mesh windows to view the sky
any tent will allow some view of the sky through mesh door or window but very few allow a wide ceiling mesh especially uninterrupted by poles and very few allow this to be removed (eg. OzTent RV Plus series)
viewing stars through mesh will result in stars being dimmer (perhaps 0.5-1 stellar magnitude loss), so you see much less of them and the mesh may cause diffraction effects so bright stars might appear as 3 stars
on cold humid nights, if you have exposed mesh without cover of a rain fly there is a significant risk of dew forming on the mesh overnight as the temperature drops and this will then fall into your tent getting you wet!
place the rain fly back over your tent if dew is expected to form (ie. temperature will drop below the dewpoint)
Tents with ceiling mesh viewable when fly is removed
most full inner mesh dome tents will allow this if one removes the fly but views will be interrupted by poles
this has a significant advantage over the Spinifex Nakara in that there is a tall rear mesh door so you don't need to clamp fly back half way and you could open the mesh if there are no mozzies around, plus you can stand up inside the tent and there is more leg room when sleeping crossways
larger tents with lots of ceiling mesh and a tall mesh rear D door:
a spacious 2P freestanding A frame tent with large TPU side windows and one end TPU window in the 3 layered fly (each have an external fly shade roll downs for privacy, all 3 layers combined can be opened to create a tarp awning effect)
inner mesh tent which clips onto the A-frame before attaching the fly
