    Hi Tico,

    I can't guarantee that you will see Barnard's loop, as we all have differences with our eyes, observing sites etc. My view of this was from a very dark sky (SQM around 21.8 at the time: zero light pollution). However, I am very pleased with the views through the 8x30 Habicht binos, and I enjoy the wide-field star-scapes! Day-time views are also excellent, with a lovely 3-D view and vibrant colours.

    They do have excellent contrast, and with them I have seen the North American nebula and the Veil nebula as a faint circle (very low on our northern horizon). The "Dark Doodad" in Musca is easy with them too. The Swan is quite small but easily visible.

    Like anything that is expensive, it would be great if you could "try before you buy", but I don't think you would be disappointed with them. Remember of course that they are only 30mm objective diameter; and you can't beat the laws of physics!

    A minor disappointment with them is the included accessories. The case is only really useful for storage (Swarovski discontinued their lovely leather case many years ago), and they don't have objective lens covers. I carry mine in a small leather "man bag", and I bought some cheap objective covers (for about $2...).

    All the best, and have fun shopping (and viewing!!!).

    Re: Barnard's Loop

    Hello all,

    the Barnard's Loop in Orion requires binoculars with large exit pupils, and under my suburban-to-country skies the H-Beta filters.
    So, you should look after the binoculars giving you at least 5mm or 6mm, or even better the 7mm exit pupil, with the option to mount the H-Beta filters.

    One of the good choices are the 2.3x40 Gucki with the 2" filter holders, AOKswiss online - deutsch
    released in the high quality standard as required on the Swiss markets.

    I take for the Barnard's Loop the 7x42 Leica Ultravid, which allow to push the Astronomik H-Beta filters into the EP barrels,

    Best,
