1. PRODUCT DESCRIPTION
Precision-engineered star diagonal with BBHS mirror technology offers minimal light scatter and intensified color rendition of brighter stars, planets, and the Moon, even at high magnification
Improves visibility of faint stars and deep-sky objects
Suitable for use with fast refractors as well as with long focal-ratio telescopes
Configurable with 1.25” and 2” Baader T-2 nosepieces, 1.25” eyepiece holders, and other accessories (not included with this diagonal body) to suit a wide range of telescopes and applications
Full 33mm clear aperture
Offers a compact size and short optical path where space is at a premium and short back focus is essential
Superb mechanical fit and finish
Note: This Baader T-2 90-degree Maxbright dielectric mirror diagonal consists of a diagonal body with mirror ONLY and includes no nosepiece or eyepiece holder. It has standard T/T-2 threads at the input face (with female T/T-2 thread on the telescope side) and at the output face (with male T thread on the eyepiece side). This lets you add Baader Planetarium T-2 adapters and accessories to configure the diagonal to your needs.
A Fully Customizable Diagonal Body
One of the key features of this Baader T-2 diagonal – and all Baader diagonals, whether they use prisms or mirrors - is the large free aperture and the flexibility to directly adapt to almost any telescope system, without the restriction of a 1.25" barrel size which may cause vignetting in long focal length 1.25" eyepieces or when using the diagonal with a binoviewer. That is precisely why Baader offers the body of all their T-2 System diagonals without adapters. The clear aperture of this diagonal body is 33mm
.
Baader Planetarium has worked hard to make the finest and most precisely-engineered star diagonals on the market today. This mid-sized and highly flexible Baader T-2 90° diagonal body with Broadband Hard-Coated Silver (BBHS) mirror is ideal for high-power planetary viewing and general deep-sky observation. The diagonal works well for systems where back-focus or space is limited and a full aperture 2" diagonal will not work or is not flexible enough.
The BBHS mirror diagonal is ideal for use with any telescope including fast refractors that may suffer from the slight spherochromatism caused by prism-based diagonals. The tradeoff is slightly longer optical path length. The effective optical path length of this base T-2 diagonal with Maxbright dielectric mirror is 43mm.
Baader BBHS Technology for Ultra-High Reflectivity and Superior Color and Contrast
This diagonal uses a silver-coated mirror made with Baader’s Broadband Hard-Coated Silver (BBHS) coating process on a low-thermal-expansion Sitall ceramic substrate. In the past, silver coatings fell out of favor because they exhibited inferior durability to aluminum. That’s why Baader uses a new and proprietary hard dielectric coating process to seal and protect the silver layer to give vastly improved durability that rivals that of aluminum.
Compared to aluminum coatings, even 'enhanced' aluminum, silver has very high and uniform reflectivity across the visual spectrum and beyond into the infrared and ultraviolet. Baader's BBHS and dielectric coatings also deliver high reflectivity across a wider visual spectrum, resulting in improved color visibility, saturation, and contrast when compared to aluminum and all-dielectric mirrors. BBHS coatings also deliver noticeably less scatter than all-dielectrics, resulting in improved contrast and reduced haze and stray light.
The brilliance and color rendition of Baader’s BBHS-coated mirror diagonals, are simply breathtaking, especially when observing with outstanding telescope and eyepiece optics. Experienced observers can distinguish richer colors on Jupiter, Saturn, Mars, and the Moon, as well as in bright stars, especially when the diagonal is used with apochromatic and ED refractors. The Baader BBHS coating intensifies visual color perception across the spectrum, especially at the red end, to a degree not possible with dielectric-only or multilayer aluminum reflective coatings.
Experienced visual observers also note that Baader’s BBHS silver coating enhances the views of faint stars and other celestial objects compared to dielectric and prism diagonals.
Configuration Suggestions
You can configure the T-2 Maxbright mirror diagonal to exactly suit your viewing requirements. The input and output T/T-2 threads integrate with the full range of Baader Astro T-2 System components and other T-threaded adapters. The telescope side can be configured to fit 2" or 1.25" focusers, as well as directly onto telescopes with specific threads such as original M44 Zeiss threads, Vixen OTAs, or Russian Maks.
The eyepiece side can be configured with 1.25" eyepiece holders. Or it can be used with Baader's quick change ring #6 to mount the Mark V binoviewer to achieve the shortest possible backfocus distance between telescope and binoviewer. It’s also the perfect diagonal for the Baader / Zeiss Giant Binoviewer (it replaces the normal prism diagonal) as well as the Baader Maxbright Binoviewer. With the right accessories, this diagonal also integrates well into digital imaging applications.
The diagonal body weighs just 6.0 oz (170g).
NOTE: This diagonal gives images that are upright but left-right reversed.
Manufacturer part number: MAX-1S or 2456103.
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.
