Cases, carrier bags and much more.

Telescopes, mounts and accessories are precision devices that can only be enjoyed if they cannot be damaged or misadjusted by impact.
Optics and electronic accessories (e.g. cameras, controllers, etc.) should also be protected from dust.

The days of DIY have been over for some years now, as there are now a large number of practical carrying bags and cases that offer excellent value for money.

Protect your optics from excessive impacts, bumps, crushing/crushing.
If possible, optics should be transported strapped to a bag on the rear seat bench.
The axle clamps on mounts are released during transport (unless specifically stated otherwise) to prevent impacts on gears and worm shafts - the heart of every mount.
After an observation, leave everything open to dry (but not on a heater!) and only pack it the next morning.
This way you will have a lot of fun with your equipment.

You will find the best of the best here.
