Description

Our newest and largest XL Series Binocular Telescope features 5″ apochromatic (FCD100 / FK-61 triplet) objectives, with a relatively-short 650mm focal length. The BT-127XL-SD was designed to be the highest-performing production binocular on the market, without regard to cost. Even with two 5″ triplet objectives and massive prisms, magnesium-alloy construction makes it remarkably-lightweight at just 24.5 lbs. With its unmatched image quality, we think it’s a much more practical alternative to the world’s largest 150mm binoculars, which are very heavy, very expensive, and difficult to mount. Finished in iridescent “Luna Pearl” White with silver anodized trim, it’s also quite attractive.
The BT-127-XL-SD includes our premium 14mm (46x) 70° AFOV eyepieces. 30x (22mm) and 93x (7mm) are also available. The included heavy-duty case has wheels on one side for easy transport.
Every BT-127XL-SD is tested and tuned to perfection prior to shipping, with collimation certified to 163x. 3-year Limited Warranty.

Mounting Options:
Recommended tripods are the Oberwerk TR3 hardwood tripod or the Manfrotto 161MK2B, which has a crank-up elevator. Either tripod can be configured with the Oberwerk XL-280 Fork Mount or Manfrotto 612 NitroTech Head.
Fully-automated “go-to” operation is available using the iOptron AZ Pro- details here.

    I purchased previously the BT-100 and it was a great design quality workmanship,
    I am so excited and can’t wait to get the new BT 127 model

    My BT 127’s arrived safely and well packaged. I want to thank you folks for the T shirt and ball cap as well.

    I have been using these binos for weeks. I have enjoyed them each time I get behind the eyepieces. I wanted to do a review after my trip to Moab, UT. The skies were better than where I live in AZ. I could not ask for better skies the nights I have been in Moab.

    The last few weeks were playing around with different eyepieces for my 127’s. I found I am very comfortable at 27 to 52x. To me this is where these binos performed. Once one obtains the eyepieces they are comfortable with – the possibilities with these binos are endless!

    The glass is everything I wanted in a BT. I was so blown away by the wonderful sights I saw. Again (as I say a lot) everything was in my face. Some of the examples of many picked objects were:

    M104 – the dust lane could be made out as well as the core.

    M65/66 – these were like looking at smaller versions of M31.

    M81/82 – both were beautiful at 52x. M81 looking like m31 (again),
    and M82 had that dust split in the middle.

    M13 – WOW! Talk about the mottling of the outer stars, and a
    beautiful center. So impressive at both 27 and 52x.

    Carbon stars like T Cancri, and X Cancri were drop dead gorgeous
    with their blood red color.

    Double stars like Albereo, Cor Caroli, and Castor are sharp and tru to color.

    These were just a few examples of how well these binoculars perform. I am constantly looking further into deep sky all the time with them. Again the possibilities are endless with these BT’s.

    I have my 127’s perched up on the Oberwerk fork mount, which may weigh more than a fluid head, but I am comfortable using fork mounts. It does require a bayonet adapter if one is considering using a 161MK2B tripod. This set up is unbeatable with an astro chair to make it complete.

    The case these binoculars come in, is solid in structure. The wheels make toting the binoculars very easy.

    Overall, the 127 BT is a stellar performer, and is a keeper with me. It is solid construction and does have an attractive finish. These binoculars are for the serious hobby astronomer who demands performance and portability of a giant binocular.

    Thanks again Kevin for making this possible. These binoculars are definitely the flagship of my astro arsenal.
