Just a heads up in case you have one on your kit.
I have been using a 12v SVbony dew strap for 11 months, and a few days ago I took my rig apart to fit new scope and sell my mint Skywatcher Esprit 100, which was in unmarked condition, wrong, when I removed the dew band it’s left a mark all around d the full dew shield, not sure if it’s a scorch mark or just dyed the paint, but I have tried everything and it will not come off, it’s there for good.
Now I am not the only person this has happened too, the exact same had happened to 2 other people I know of.
the dew strap was used with the supplied controller on level 2, from a 12v supply, and then connected to the Pegasus controller on auto dew setting with 75% max setting. so just as it should have been
I am in contact with SVbony on why this should have happened, but I think it’s a combination of a poorly made and much too powerful (20w 😮) dew strap, and very poor cheap paint on the Esprit scope tube.

No, I have tried it all mate, even strong cutting compound, and it’s made no difference, trust me I would not have posted this if I had not tried everything first, I worked for 3M and have all sorts of car paintwork chemicals and no this has worked…☹️

Same on my Askar 120APO. 

I am going to replace it with a Prima Luce Lab one… it certainly doesn't get hot enough to be a burn, but I think it might be heat transferred dye from the black of the strap…

Yes, I think your might be correct, it’s seems to follow the line of the stitching around the edge of the strap…
Contact SVbony and they will refund the cost of the dew strap, and are still talking with them on sorting it out long term..👍🏻

Dye from the band absorbed into the paint.   Not a heat thing.   No clearcoat to stop it like your automotive stuff.    Now the next user knows exactly where to place the dew shield for maximum effectivity.

Side note, I don't get why a telescope has to be 100% spot free immaculate for people.   It's silly.   These tools stay outside for hours at a time, if not 24/7.   Birds crap on them before you wake up.  etc.    Skywatchers paint is actually pretty good, it's the annodizing that fades over time, black becomes gold.    Somehow this devalues the product to people, I just don't get it.    The quality of the glass is all that matters to me.

Agreed.  Maybe astroimagers are perfectionists and that is where it comes from.  But function should be the word of the day and cosmetics are not the least bit critical.

I bought a "second" Paramount ME direct from Bisque way back in 2007 or so and the only issue was some blotchy anodizing. It served me wonderfully until I upgraded to an AP 1600 last year and I expect it continues to serve the buyer well. It also saved me $1000 compared to a "perfect" one.

Even optics with some minor  blemishes are not critical and I have a Stellarvue SVQ100 that I have had for sale at a big discount that has had no takers because it has some exceedingly minor spots on the coating that have zero effect on images.

IMHO Telescopes are not car show items . Images are what we are after and the rest is just unimportant.

Of course, having said that, a dew strap surely should not dew (pun intended) that and the information is good to have.

No maybe what the scope looks like does not matter, but if you read my initial post you will see that I m annoyed as the scope was mint, and I took it off the mount to sell, and now I can’t sell it as mint condition, unmarked scope, so it’s actually devalued it by a lot, so I think I have every right to be upset and annoyed, if I was keeping it, then I would live with it, as it does not affect the usage of the scope at all…
that was my point

Presuming everything else is perfect, that scope is still mint in my book.

Absolutely not, mint is mint, and totally unmarked, simple as that, in the eye of the buyer.. 😉

I guess the difference in oppinion here, is that Brian, and myself for that matter, consider a telescope to be in perfect condition if the optics are in perfect condition, the focuser works perfectly, any accessories like correctors/reducers are completely clear and free of fungus, scratches etc.. 

I will HAPPILY pay the usual 'used' price for a telescope that has marks on the tube, sticky residue from stuck on controllers, custom modifications that aid in the telescopes performance etc... It looking pristine is literally the last thing on my list of requirements... As with Brian, I reckognise that my scope lives on a mount in a tin shed 24/7 and stays outside under damp, dewy conditions for 9h per night every night during winter... 

If I were buying something REALLY fancy and wanted it to be 100% pristine and unmarked, I'd buy it new... The fact is that if I buy something listed as 'mint condition', ANY signs of use AT ALL will make me mad, because that is not what was described. But I'm more than happy to buy a scope that says 'optically and functionally perfect, Its been in my observatory for the past 5 years and has seen MANY nights of use... 

Everyone is different I guess, I don't at all feel like the mark on my 120APO devalues it at all... Its annoying that it happened, but the scope provides BRILLIANT images. I'm not too concerned.

If I were a buyer I wouldn't care for the reasons others have already outlined, paint isn't expensive if it really mattered to me

Use is used also. My starting point , buying or selling is 50% of new price regardless whether the seller thinks it is mint condition or not.
You are stressing way too much about it, it won't matter when you sell it, You will get 50 to maybe 70% of new price regardless of condition.
