While an excellent telescope that has upped my astrophotography game, the Sky Watcher Quattro 200P is starkly open on the back side near the primary mirror (similar to an issue near the focuser tube). In fact, most of the back is just the frosty mirror glass! If you happen to be in Bortle -1 skys so dark that your indicator LEDs are sympathetically dimmed, this might not be an issue. The rest of us are in our front yards under Bortle 8 with the Christmas lights on under a full moon, and that light, and dust, and whatever else is leaking in past the mirror.
So, I made this cover, which doubles as a stand to prevent load to the primary adjustment screws when placed on the rear. Really, not sure why the telescope didn't come with something similar.
Update: added an extra snug version, which fits better in cold weather when the TPU tends to contract. Works well in warm weather, too, but a bit harder to install.
Suggest printing with black TPU, several perimeters, many top and bottom layers, with ≥20% infill. Some flex is required to install, and the fit is snug, so a flexible filament is recommended.
