My 10" Goto Dob, which has a gorgeous black and white paint job, has just one very special sticker on it.
A black and gold Ulbrick tag.
My White and Gold ED80 has a sticker on the dew shield saying for people to keep their hands off my scope or I'll beat them to a pulp.
My first Dob, a bog standard GSO 10", I decorated with ink. Putting celtic bands around it, American Indian designs, etc etc It definitely did not look like every other dob on the field.

On the draw tube of all my scopes I mark the focus points of my various camera and barlow combos.

I don't own telescopes just to look at them and admire how pristine they look.
Telescopes are meant to be used and loved. Some wear and tear is to be expected on an object used for 8 hrs a day or more.
What matters the most is the care you take with the optics.
