    Default Can someone identify this telescope accessory for me?



    Hello,

    I recently came into ownership of the item pictured below, and I am hoping that someone can help me identify it. Some basic Googling has led me to believe that it is an off-axis solar filter for a telescope. Astronomy is not one of my hobbies, and I know next to nothing about telescopes. I'd like to know exactly what I have, and, specifically, how much it might be reasonable to ask for it if I decided to sell it. I very much appreciate any help that anyone can give me.

    Hello Ubernoob,

    These are examples of off-axis-solar filters. The filter material is made of glass with a special coating on it.

    https://spectrumtelescope.com/produc...solar-filters/

    In Europe roughly 45-65% of the value is considered as a normal used-price. Or less, depending on age and user-marks. A scratched or worn solar filter (local discoloring) will probably not be bought. Since the intense light of the sun is involved ( risky!) many amateurs will prefer a new one.
    Telescopes in Schiedam : SW Evostar 120ED F/7.5, Vixen 102ED F/9, OMC140 maksutov F/14.3, SW 102MAK F/13 on Vixen GPDX.
    Binoculars: AusJena 10X50 Jenoptem, Swarovski Habicht 7X42, Celestron Skymaster 15X70, Swift Observation 20X80.
    Astronomical Rijswijk observatory telescopes: Astro-Physics Starfire 130 f/8 on NEQ6, C8 on NEQ6, Meade 14 inch SCT on EQ8, Lunt.

    What is the diameter of the filter? The DIY storage case is really nice.
    Like John said, if the filer is blemish free expect to get about half of the retail price. The custom storage box adds value.

    Thanks Scott -- the diameter of the filter is 3.5 inches. I was really hoping that there might be some way of verifying the maker and model of this filter so I might get an idea of where to start with pricing. 45-65% of retail sounds fair, but unless you know what retail actually is, it's hard to figure. More importantly, I don't want to advertise it as a Questar filter if that's not what it actually is.

    Gabby76 thanks for the suggestion! I actually discovered Company 7's website right after I posted to this forum. I did email them and someone got back to me within a few hours and confirmed that what I have is an older-model off-axis solar filter made by Questar.
    He did not say anything about pricing, but he did caution me to get the filter evaluated to try and find out how much use it's had already before selling it, because, as he said, "there are too many people out there looking for someone to sue." Good advice.
    So, now I know what I have...I just need to find out if it's safe to sell, or if anyone would buy it if I did put it up for sale.
    Thanks to everyone who responded to my post for your help!
