1. PRODUCT DESCRIPTION
New, improved version of Blue Fireball's X-05 eyepiece extension tube - with twist-lock, self-centering mechanism!
This high-quality Blue Fireball extension tube can be inserted into any 2" telescope focuser to gain an additional 80mm (3.15") of back-focus travel. With this, eyepieces and accessories that you may not have been able to use because your telescope tube was too short are usable again!
Lack of sufficient back-focus travel is a common problem with many of today's fast f-ratio telescopes, especially if you have a low profile focuser or a short telescope tube that is optimized for binoviewer viewing. The 80mm extension tube alleviates this problem. This tube can also be used with 1.25" accessories with the use of commonly available 1.25"-2" adapters (sold separately).
With this adapter, you can forget about fumbling with thumbscrews in the dark. Just twist and lock the knurled twist lock ring at the top, and your 2" eyepiece or other accessory will be centered precisely.  The helical centering mechanism is controlled by an inner polypropylene compression ring that will not mar your eyepieces. Its long length ensures that the adapter works well with smooth and recessed eyepiece barrels.
It also includes a large thumbscrew should you feel the need to provide added security for heavy items after you have tigthened the twist lock ring; however, use of this screw is optional and not required for regular use.
This practical and superb quality adapter is made from precision machined aluminum and is black anodized. The inside surface of this tube is black-matted to enhance contrast by reducing stray light reflections and is threaded to accept standard 2" telescope filters.

4. INTERNATIONAL ORDERING / SHIPPING
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.
Delivery Time:
1) USPS First Class International:
Delivery 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 NO TRACKING FOR FIRST CLASS SHIPMENTS. The information shown in your eBay account is just a customs form number - it is NOT a tracking number as incorrectly indicated by eBay.
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 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, then DO NOT USE First Class mail - use Priority or Express shipping instead.
(2) USPS Priority Mail International:
Delivery takes 1 - 2 weeks 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.
(3) USPS Express Mail International:
Delivery usually takes 5-10 business days after we ship your package. You will receive a tracking number with which you can track your shipment from USPS.com. Note: If you use this option, you must send us your phone number when you check-out or else your shipment will be delayed. This is required for international postal forms.
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 Paypal claim if your package is delayed. Delays are quite common but losses are very rare, so your patience/cooperation will be greatly appreciated.
Customs and Duties:
You are responsible for any duties and taxes that may be levied in your country. These are not included in the item price or shipping cost. 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 bidding or 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.

5. RETURN/EXCHANGE POLICY
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.
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.
