Description Ordering Info USA Shipping International Orders Returns Our eBay Store 1. PRODUCT DESCRIPTION Please Note: This mirror in stock at this time is NOT center-dotted. For years, GSO has made dobsonian telescopes sold under various labels. Users of these scopes know the excellent quality of the optics included, and they have a well-deserved reputation for being the finest mirrors in their price range. We are now pleased to offer virtually the entire line of GSO’s Newtonian optics in the US market. GSO’s parabolic primary mirrors are perfect for those who want to build their own telescopes or replace mirrors in older ones. Ranging in aperture from 6” to 16” and offered in various f-ratios, these mirrors are made from optical grade BK-7 glass. All mirrors have a reflective aluminum coating with a reflectivity of 92-93%. The aluminum coating is protected by a silicon oxide (SiO2) over-coating. GSO uses high-volume, state-of-the-art, high quality manufacturing and test lines. GSO guarantees diffraction limited performance, but their mirrors typically have a mirror surface quality of 1/16 wave RMS at least, and often better. This very smooth mirror surface results in excellent optical performance with practically no light scatter. Besides parabolic primaries, we also offer matching GSO secondary elliptical mirrors, mirror cells, and spiders (all sold separately). Please Note: Most parabolic mirrors will have 2-4 minor uncoated areas along the edge of the mirror. See photo 2 above for an example. These are caused by the clips used to hold the mirrors in the coating chamber. Note that these are not defects. A couple of these uncoated edge strips will typically be covered up by the clips in your mirror cell anyway. Additional Information: Q. Is a test report included with each mirror? A. No. GSO tests each mirror via laser interferometry before shipping, but does not provide individual test reports. Q. Is the primary center-dotted?A. Sometimes yes but mostly no. It just varies from batch to batch. You can easily center-dot the primary yourself if the mirror you receive is not dotted. Instructions to do this are readily available on the internet. If you want a center-dotting sticker, just request one from us at the time you place your order.If you want a mirror that does not have this center dot, please check with us before your purchase. Removing the center dot is not easy or recommended. If the mirror already has a center dot but you do not want it, we recommend that you not purchase this item.

Actual coated mirror diameter will be 2-3 mm less than the Mirror Diameter listed above. Taiwan Note: Occasionally, the product you receive might have a slightly different cosmetic appearance or labeling than what is shown. This can often change from batch to batch according to the whims of the manufacturer. However, you will always receive a brand new, original product as described above. Back to Top 2. ORDERING INFORMATION A. Payment: You can pay via any payment method that eBay accepts. B. Shipping Method: United States Postal Service (USPS) or United Parcel Service (UPS) at your choice and expense (our choice if the item has free shipping option). eBay orders for items over $1,500 can only ship via UPS. C. Order Processing Time: Orders received by 12 noon Mon – Fri US Pacific Time generally ship on the same business day. Orders received after 12 noon PT or on weekends/holidays will ship by the next business day. D. Checkout: Please pay for the item(s) within 3 days from your account on eBay or by using the link in the email you receive from eBay. E. Shipping Discount: We offer combined shipping if you order multiple quantities/items and if items can be combined. eBay will automatically show you the correct combined/discounted shipping costs when you check-out. F. Combining Purchases: You can combine shipping for items purchased from us on eBay within 3 days. Buy the items individually and check out together for all items. eBay will combine the shipping weights and show you the discounted shipping cost. You must check out for all items together via eBay for this. We cannot combine shipping costs if you check out individually for your purchases. G. Sales Tax/VAT: Sales tax or VAT may be charged and collected by eBay as required by law based on your ship-to address and local tax/VAT rates. Please check with eBay. Back to Top 3. US SHIPPING A. Delivery Time: USPS First Class shipments will generally take 3-5 business days to arrive after we ship it. Priority Mail shipments will generally take 2-3 business days. However, these delivery times are NOT guaranteed by the USPS. Delays of up to 2 (or sometimes even 3) weeks can occur in about 5% of the shipments due to Covid, operational, or other issues. UPS shipments will generally take between 1 and 6 business days to be delivered depending on the method you select. USPS and UPS do NOT offer any refunds for shipping/delivery delays for ANY reason (except for UPS Next Day Air service). Delays are out of our control once your order ships. B. Tracking/Delivery Confirmation:eBay will update you once your order ships. You can see the order status or tracking information/link from your eBay account at any time. C. USPS Tracking Limitations: Please note that is common for USPS tracking to show “Shipping Label Created, USPS Awaiting Item” or “Shipment Received, Package Acceptance Pending” even several days after your order ships. This does not mean that there is a problem with your order or that we have not handed over your package to USPS yet. This simply means that your package is en route without an outbound scan and tracking will not be updated until the package reaches a distribution center at your end several days later. Back to Top 4. INTERNATIONAL ORDERING / SHIPPING A. Shipping Cost: Click on the “Shipping and Payments” tab above and select your country to see your shipping choices and cost. If you need a shipping cost estimate for multiple items, please contact us. B. Delivery Time: Please note that eBay’s delivery estimates shown are generally too optimistic! 1. UPS (All Shipping Methods): We strongly recommend the use of UPS for international orders due to issues related to the ongoing Covid situation. Delivery time usually varies between 3-7 business days depending on your country and the exact shipping method you select. 2. USPS First Class International: First class packages will usually be carried by GlobalPost (a USPS international delivery partner) for most of the way. Delivery at your end will be handled by your local postal service. Delivery generally takes about 3-4 weeks after we ship your package. This can frequently take 4-6 weeks or more for several countries (8 weeks for Italy, Argentina, and South Africa; 8-12 weeks for Brazil). There is very limited tracking available for 1st class shipments and there is no inquiry/tracing service. Once your package ships, we can do nothing but wait until your package arrives. Please do not become impatient and contact us in 2-3 weeks if your package has not arrived. If you don’t receive the package in 6-8 weeks, contact us and we will work with you to resolve the issue. If you don’t want to take the risk of this delay or lack of tracking, DO NOT USE First Class mail – use Priority or Express shipping, or better still, UPS instead. Packages are not considered lost unless 60 days have elapsed from the date of shipment. 3. USPS Priority Mail International: Delivery takes about 2 weeks to most countries after we ship your package. This can sometimes take 3-4 weeks to several countries. The USPS provides some basic tracking information for Priority shipping. Packages are not considered lost unless 60 days have elapsed from the date of shipment. 4. USPS Express Mail International: Delivery usually takes 5-10 business days after we ship your package. Packages are not considered lost unless 30 days have elapsed from the date of shipment. Again, these delivery times are NOT guaranteed by the US Postal Service. The most common reason for delays is slow customs inspection and clearance in your country, and can be very long, even for Express mail packages. Upon shipping your order, delivery delays are beyond our control, so do not leave us negative feedback or file a claim if your package is delayed. Delays are quite common but losses are very rare, so your patience and understanding will be greatly appreciated. C. Brokerage Fees, Customs and Duties: You are responsible for any carrier brokerage fees and duties/taxes that may be levied in your country. These are not included in our item price or shipping cost. UPS brokerage fees can be quite hefty. We have no control over these charges and cannot predict what they may be or if they will be levied upon delivery. Customs policies vary widely from country to country (Some countries such as UK are strict about imposing hefty customs duties). It is your responsibility to check with your country’s customs office to determine what these additional costs will be prior to buying. Customs fees are normally charged by the delivery company or your country’s postal service or collected when you pick the item up. These fees are NOT additional shipping charges. Back to Top 5. RETURN/EXCHANGE POLICY A. US Orders: Returns must be shipped back within 30 days. All returned items must be in brand new, resalable condition with original manufacturer’s packaging. A minimum restocking fee of 10% will be deducted if there is any evidence of use or wear, dirt, scratches, missing packaging/parts, etc. We may levy a larger restocking fee if the condition warrants it, or even refuse returns entirely if returned in heavily used/abused condition. Shipping fees are non-refundable (for items with free or discounted fixed shipping, the actual outbound S&H cost we incurred will be deducted) and you are responsible for all return shipping costs. Please contact us first before returning an item. B. International Orders: No returns/exchanges accepted unless the item we shipped is defective. Please research the product and ask us any questions BEFORE you purchase to make sure you are buying the correct item for your needs.
