Hi all,
Not sure if I should have posted this here or in the beginners thread so my apologies if this is not the most appropriate place.
I’m very much a beginner to the astronomy scene and i’ve just bought a Baader Hyperion zoom lens for my 10” skywatcher and wanted to get advice from IIS members about a couple of perceived problems with the eyepiece. I received the eyepiece today and upon inspection I noticed it has two visible defects/imperfections in the coating underneath the top lens. One spot is ~0.5mm in diameter and the other ~0.25mm and both are located in the centre part of the lens.
In addition, at the bottom of the eyepiece there is a very slight but obvious dent on the edge of the outer sleeve in which the inner barrel slides (my apologies if I am not using the correct terminology or if my description is poor) suggesting that the eyepiece has been dropped slightly (without the adaptor on) or something has been dropped onto it. This dent is right on the very top edge of the barrel and doesn’t appear to be affecting movement of the eyepiece zoom. It’s probably only a cosmetic issue (and a trivial one at that) but I expect a brand new eyepiece to look brand new and I am concerned about the potential implications for what may have occurred internally if it was dropped.
The eyepiece rattles slightly if you turn it upside down although I don’t think this is a problem as a quick perusal of the internet suggests this is standard for these eyepieces. However, I would be reassured if somebody who has/had this eyepiece could please confirm that slight rattling is normal?
Due to work commitments, I probably wouldn’t be able to test the eyepiece for at least the next few days and given my inexperience I may not pickup if these defects are causing slight problems. Obviously I want to get this sorted ASAP so I was going to ring up the supplier to ask for an exchange tomorrow but I wanted to confirm if others think these defects are unacceptable in a brand new eyepiece before I do. I’m not anticipating having difficulty with the supplier (Andrews comms) but would like to be informed just in case I do. Alternatively, if I am simply being unrealistic in my expectations I’d rather hear about it first from IIS members rather then the suppliers as I don't want to make unrealistic demands and have any associated aggravation as a result of my inexperience.
Sorry about the long-winded post for such a simple question. Brevity has never been a strong point of mine!
Thanks in advance,
Steve
