Baader Canon EOS DSLR T-Ring with UHC-S Nebula Filter # DSLR-UHC 2958550N

Please note: It is common for the filter substrate to sit loosely within this adapter as received from Baader. Hence, it might rattle a bit if shaken. This is not a defect and there will be no negative impact on performance.

Today's large sensor digital SLRs and advanced imaging techniques enable amateurs to take spectacular high resolution and long exposure images that push the limits of modern telescope optics. Until now, the only means of coupling a DSLR to the telescope relies on the use of a standard mass produced camera T-Ring. However, T-rings, albeit convenient and popular, do have limitations:

The use of 42mm T-thread for the coupling causes a choke-point in the imaging train (typcially 38mm internal diameter), possibly resulting in vignetting in fast systems.
High resolution digital image sensors and their protective glass covers are highly vulnerable to dust that can enter the body each time the camera is coupled/uncoupled, or in open systems, particularly if the camera has been modified for full-spectrum use.
Many cheap T-rings are mass-produced for generic camera use, with general manufacturing tolerances and design, which result in a potentially loose bayonet fit that can cause focal plane squareness and long-exposure image shifting from lateral play and angular wobble.

Baader's New Protective Wide T-Ring System for the Canon EOS series cameras evolves the T-Ring and solves these issues.

The 2" wide aperture of the protective T-ring accepts 3 different attachment adapters, which are included with each T-ring: Standard T-thread (42mm), 2" thin profile nosepiece, and 48mm thread (astro filter standard).
The internal filter compartment is able to accept both Baader 2" mounted filters, and 50.4mm diameter unmounted filters for the widest clear aperture possible (47.3mm aperture).
The optimized design and tight manufacturing tolerances ensure the closest fit possible with the Canon EOS body. This avoids the occurance of focal plane tilt and image shift caused by play and wobble at this connection point.

The Baader Protective Wide T-Ring System includes 6 configurable parts:

Protective T-ring Body
Temperature Compensation Ring (for installation of 50.4mm x 3mm unmounted filters)
Adapter S52/M48 (for 48mm connection thread)
T-thread/M48 adapter (for standard 42mm T-thread connection)
S52/2" wide aperture 2" nosepeice (includes M48 filter thread)
1.5mm Allen Wrench

In addition to the basic system, this Protective Wide T-Ring system also includes a pre-installed Baader 50.4mm x 3mm UHC-S Nebula filter.

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.

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.

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.

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 1^st 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.

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.
