Description Ordering Info USA Shipping International Orders Returns Our eBay Store 1. PRODUCT DESCRIPTION Another unique new filter from Baader Planetarium. For the first time, amateurs can now record cloud structures on Venus. The Baader Venus Filter enables amateurs to successfully image in the deep UV, a spectral region normally inaccessible. The latest coating technologies permit the Baader Venus Filter to transmit from 300nm to 400nm, with a peak transmission of 80%! The filter completely blocks the rest of the region from 200nm to 1500nm, through the use of a complex 20 layer dielectric coating stack, on top of a special optically polished UG-11 substrate. Until now, amateur efforts typically relied upon deep violet colored filters, or combinations with simpler interference filters, which do not provide the high transmission and efficient rejection outside the important spectral region from 320nm to 390nm. Given the poor transmissions of many optics in the UV and the lower sensitivity of some CCDs to this wavelength, high filter efficiency and complete rejection at longer wavelengths becomes paramount to recording good contrast at reasonable exposures. The same high optical quality and features as the other Baader filters ensures the highest contrast and sharpest images possible. The Baader U Filter has become the choice of UV imagers exploring the UV world of landscape, floral, and even forensic imaging. The latest 2" filter now has even higher transmission and improved out of band blocking. By using our DSLR-2 filter adapter ring plus the appropriate filter step ring (HDT-Rings), UV imagers can conveniently mount the U-Filter to their camera lens. The filter cell has a standard M48x0.75 thread. This 2" astronomy filter has an M48x0.75 thread (male on one side and female on the other). To use this filter directly with camera lenses for other applications, you will need an appropriate 48mm step up or step down ring. Please Note: The Baader Venus filter is only applicable for imaging of Venus with Webcam, Digital, and CCD cameras (Visual Observation is impossible, due to the eye's insensitivity to the UV). For successful Venus imaging, we recommend the use of a UV sensitive astro CCD camera (ie, SBIG ST-2000XM) and at least a 5" telescope, or a webcam and 8" telescope. 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.

First Class shipments will take 3-5 days to arrive after we ship it. Priority Mail shipments will take 2-3 days. However, these delivery times are NOT guaranteed by the USPS. Delays of up to 2 weeks can occur in about 5% of the shipments. Tracking/Delivery Confirmation: eBay will update you once your order ships. You can see the order status or tracking information from your eBay account at any time. Back to Top 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. Back to Top 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.
