New Scope defect?

Hi all,


Just wondering if I can get an opinion from the more experienced users out there.


I received a new refractor two days ago, just opened it today and saw what looks like a scratch or something on the objective lens .


I want to return it, but is this acceptable in the astro equipment world or am I right to send it back?

I understand that dirt etc on the objective isn't always noticeable in images as it is probably out of focus, but still, its brand new out of the box.

I have two pictures, from the front and from the focuser.
Thanks.

Are you sure that is a new scope? Certainly not acceptable. Contact the seller. Then send it back.

That almost looks like some kind of adhesive. From what I can see in the photo I would be sending that back.

Haha, fair question, but yes, Brand new from a local astronomy specialist retailer.
He seemed quite nice, so i hope there is no issue with a replacement or refund. Getting another one in Aus anytime soon is another mater at the moment .


Thanks for your opinion.
Goran.

Yes that what I originally thought, not sure. Was quite disappointed when I saw it.



I've contacted the seller, just wanted to confirm whether I was being too fussy or not. Thanks for the advice.

Definitely looks like the glue has spread onto the objective. Probably applied to the retaining ring to "lock" in place.
I'd return to the supplier for full refund or replacement.

What's already been said. That is quite a serious defect whether its glue or a scratch, either way, its bad.

Looks to me like a cleaning solvent may have "wept" out of the cell.

It may simply wipe off....a very simple remedy IMHO.

Let's face it you would not return a new car due a lone bird dropping.

AP recommend cleaning optics with acetone. Contact the seller. Ask whether they are OK with you gently cleaning the lens....as this simple fix may be a whole lot easier and less costly in time an money than returning it.

If not. Leave it alone! Return it as is.

Judging by the adhesive on the edge of the lens cell it is adhesive on the lens
but if it was me I would send it back and get a new one as you did pay for a new scope with no defects should have been checked before leaving the shop or is that to old school

There are any number of posts on the net that cite gripes about: shock! horror! the factory-fresh box had been opened before I got it!

Yes, the optics should not have had any gunk on them.

But the manufacturer, not the retailer, should have made sure the contents were fine....and perhaps they were.... that gunk may have leaked out
post "boxing"

If a simple wipe of an acetone soaked Kleenex fixes the problem, it's a pragmatic and simple solution. If not, send it back!

I tried to gently wipe it, it has a thickness to it, so i dont think it would be solvent.



And if the Bird droppings had eaten into the paint of a new car, i definately wouldnt be handing over a cheque until it was replaced.

Well, sounds like you have already contacted the seller so the best thing to do is give them a chance to respond. Is that an Evostar scope? Looks like an O ring under the locking ring which is what my 72mm had, and a dob of adhesive to keep the locking ring form loosening. That one does not looks like it has crept out onto the glass to me, looks more like a spatter from a bit of air in the tube when they applied the adhesive.

It has been mentioned above, I don't know which way the retailers can go to get a win. Some people get pretty upset if the boxes have been opened and accuse sellers of foisting secondhand or returns as new goods, when what it really is, is a new item that has been inspected by the retailer.

Err...the solvent would have long evaporated, and left whatever that gunk is.

Not happy? Simply send it back.

A reputable vendor will have no problem with that.

.....but what I am not seeing from you is their opportunity to remedy/respond prior to your post.

If you had said..."it turned up like this and they told me to bugger-off" it would be worthy of a user group posting.

No need to get upset mate, I have not accused anyone of anything. In fact, I said that the vendor seemed pretty good and was confident that they will be fine with it. And in fact, they are, and may even have read this post. I never mentioned Who the vendor was, nor that I was unhappy with anything other than being disappointed with what I had in my hands, again, not blaming anyone.
My original post was " Is this acceptable or should I take it back". That's all. If the consensus was that it happens all the time and doesn't affect your imaging and was normal for this equipment then ok. But, as I suspected, it shouldn't be that way and so I will return it.



What I have learned most of all though, is that some people are helpful, and some people are not. And i will think twice before posting a simple question in the future on this forum, which is quite sad.

Not upset at all.

I was simply puzzled by the sequence of events.

Clearly a problem.
Vendor happy to fix.

Good luck with it, but from what you've said, I'd expect a happy ending.
