1. PRODUCT DESCRIPTION
Important note:
Minor optical imperfections (such as a couple of tiny dust particles between lens elements, uneven lens edge blackening, very minor coating blemishes, or even a very small fine lens scratch or two) are very common in most Antares products and must be accepted as normal. However, these will not impact optical performance. Also, Antares' products often have rough mechanical finish and sharp edges are, unfortunately, common as well. Despite these shortcomings, Antares products continue to be popular, especially given their price-performance ratio, but if you're expecting a perfect cosmetic product, then Antares products might not be for you.
New Photo-Visual dual use model with twist lock eyepiece holder
For observers who want to power-up their 2" eyepieces, the Antares model 2UBSTL barlow lens with twist lock offers a 1.6x increase in magnification and reduced spherical aberration with all oculars. With a clear aperture of 1.52" (38.6mm), this fully multicoated achromatic design will work with telescopes with the 2" format, including those using a 2" diagonal.
This new version of Antares' popular 2UBS barlow features an integrated twist-lock adapter / clamping mechanism to securely center and hold your eyepiece. The inner compression ring is made of polypropylene and will not mar your eyepieces.
The barlow features edge-blackened elements and internal baffling. When used with a diagonal, this barlow will provide approximately 2.4x if placed before the diagonal or 1.6x if inserted into the diagonal.
And that is not all. An innovative design tweak allows you to attach a DSLR or other camera to the lower part of the barlow to use it as a photographic 1.6x barlow as well. Unscrewing the lower 2" nosepiece (silver barrel) that contains the barlow lens elements from the upper 2" eyepiece holder (black portion) exposes a 42mm male T/T2 thread. Just use a camera-specific T ring for your brand of DSLR (not included) to couple your camera body to the barlow via this thread.
Please note that a nominal magnfication factor of 1.6x will be maintained with Nikon and Canon DSLR cameras. The magnification factor will be smaller when used with other cameras with smaller than approx. 55mm backfocus, unless you insert additional spacers to push back your camera's image plane to get 1.6x again.

Note that the use of any optical element like barlows and focal reducers changes the focus point of your telescope, requiring additional in-focus or out-focus travel. The exact amount of focus travel required will depend on the optics and mechanics of your specific set-up (telescope, diagonal (if used), barlow, and eyepiece). Hence, be aware that you may not be able to reach focus with all eyepieces or in all configurations with a given barlow.
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.

3. US SHIPPING

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.

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.
