I have just bought Barska Gladiator 10-30 x 50 binoculars. There seems to be a yellow and  blue halo around everything I look at! Can anyone help??

This is called Chromatic Aberration - The failure to focus all wavelengths of light to the same point.

Hello and welcome to SGL . The yellow and blue fringing you are seeing is called chromatic aberration. If you are unhappy with the views you are getting through the binoculars you should return them.

Hi Sophie and welcome to SGL. :hello2:

As per above... it is chromatic abberation. Using zoom binoculars for astronomy is not ideal... and if you are seeing it during the daytime hours too, then you should return them.

Hello Sophie. Another welcome to SGL. Unfortunately, the features of this binocular are the ones that tend to attract beginners but are exactly those that the more experienced user would advise to avoid. If at all possible, I would recommend returning them and replace them with a standard 10x50 binocular. There are plenty of good ones available at a similar price, get back to this forum if you need further advice.   ?

Hello Sophie.

Welcome again. You will find lots of good advice and help on SGL. It is (in my opinion) the best astronomy forum going!

On the binos. If you can't return them for refund, then give them to child to play with.
I did that with some rubbish binos I was asked to review for a (non astro) retailer a while back.
They went down really well and I didn't care when they got broken.

When you start to look for more binos, ask around on this forum, then buy from a specialist astronomy or nature retailer.

Enjoy your visits to SGL, David.

Viewing very high contrast objects day or night will show slight aspects of this with nearly all binoculars.... only the most costly ones can virtually eliminate it. If it is very noticeable then return them, if they do what you want most of the time then keep them.
