15×70 Astronomy Binocular Review

I have never owned my own pair of binoculars before, even though it seems that as an amateur astronomer having a pair of binoculars is a must.

Binocular EyepiecesThe binoculars being reviewed are from Telescope Planet and they are their own make, and are 15×70 (15x zoom with a 70mm lens diameter). They have a nice feel to them as they have a rubberised coating, which I am told is good for grip and reduces the formation of dew.

These binoculars are good for all types of viewing but really excel at astronomy, due to their 15x magnification and 70mm lens. It’s strange to think that even some telescopes have this size lens diameter.

Binoculars and CaseThe binoculars come in their own soft case and come with a binocular strap and cleaning cloth, as well as all eyepiece covers.

These 15×70 binoculars are not light, and I did find myself only being able to hold them for a few minutes before my arms got tired and I started to view star trails with my arms shaking.  I found the best way to hold these long binoculars was by holding the end of the binoculars with both hands, instead of up near the eyepiece and focuser.

Binocular Tripod AttachmentThe good thing is that they have a standard Universal Bush built into them beneath a protective screw on cover. I would thoroughly recommend purchasing a binocular L bracket (around £10) and putting them on a tripod to get the most out of these, perhaps something I should look at purchasing next.

I could then imagine myself just sitting in the garden on a chair with the binoculars on my tripod gazing up at the stars all night long when I did not want to setup my LX200 outdoors.

Binoculars from the topThe binoculars come with a standard dioptre adjustment, and they allow you to change the distance between the eyepieces to match your pupil distance.

The focus adjuster was quite stiff and did appear to spring back a little, but it did keep focus and with a bit more use it should become easier to use.

Views of the moon were brilliant with a very fine crisp detail being provided of the lunar surface. I also managed to track satellites in the sky with these binoculars and I even managed to witness a shooting star through them, something that was not visible with the naked eye.

Binoculars and CoversOverall, a very nice pair of binoculars with good magnification and viewing, and some really crisp views of the nights sky. They also have long eye relief (77m at 1,000m or 231ft at 1,000yds)

The only disadvantage is that they are a little heavy to hold, but these would excel when mounted on a tripod using an L type bracket.


I have now managed to get a large L-Type adaptor and have easily added these binoculars to a tripod and even though it is difficult to describe what you can see with them, here is an image of the Moon, taken with a Canon 400D SLR camera pointed through one of the binocular eyepieces.

I also managed to see Jupiter again in Summer 2008 using them, and amazingly enough they allowed me to see the disc of the planet and make out Jupiter’s Moons as stars.
