A pricey but fantastic piece of equpment
Tuesday, 15 May 2018  | 

I really fell for these binoculars when I saw I could screw filters in the eyecups and also because I have another pair of binoculars from Helios which I really like. The ability to screw an OIII or a UHC filter in the eyecups or one of each is a huge plus when observing the rosette for example(yes I have seen it) or m27 which also looks quite nice with the 15x magnification. You can also see the moons of Jupiter, and Jupiter really stands out as a disk and not a star. I can observe while holding these by hand, but I also have a setup which include my manfrotto tripod and ballhead together with the binoculars and an adapter for the binocular to be mounted on the ballhead.
All in all I really like these binoculars and I would really recommend buying these if you have the money, but if you don't have the filters for it already or not willing to get filters, I would rather get the lightquest also made by Helios. They are lighter and of the same optical quality(if not better).

Overall perception

I bought the 15x 70mm just before Christmas 2013 along with the Horizon 8115 tripod. The tripod is a perfect match for these bins and even when fully extended it is rock solid, I love the pillar height adjustment being on a ratchet.

The binoculars are heavy and very substantial, The focusing takes a bit of getting used to as it is individual for each eye, Also the inter pupil separation takes some fine tuning as it is a tight movement on the pivot, Which means once it is set, It won't move a millimetre. You can grab the body of the bins to slew around without fear of losing it. In use the optics are amazing, Objects really do snap into focus with no fuzzy halo around even the brightest object,

As for eye relief, Well.. That's a slight problem for me as I wear glasses, I wish it was slightly longer, I believe it is around 15-17mm, But that's a guestimate, Fortunately I have a pair of flat lens glasses so can use these bins properly. Do check you can use these with glasses on.

I have also used them with my glasses off and in daylight they work brilliantly, At night I do loose some detail on Jupiter and the moons are fuzzy as you would expect with astigmatism, On the moon it's still crisp across a good 80% of the fov.

I have also made some solar filters using embroidery hoops and Baader solar film, The view of sol is impressive using both eyes.

I would thoroughly recommend these binoculars to anyone with any interest in Astronomy or not, Just be aware of the mid range eye relief.
