Fiery Views of Jupiter and Saturn using Andrews 11x70 Binoculars

Hi

I finally bought a new set of binoculars .. yay and am loving it. I also splashed out and got a Velbon Sherpa 250R tripod, since I found my hand wasn't steady at best of times.

While looking through the binoculars, I managed to see the moons of Jupiter (jupiter as well ) and also Saturn together with titan (a very faint pinhead).

My question is, while looking at Jupiter and Saturn, I found them to be glowing with radiance (sort of like what a diamond is under white light). It sort of had an aura around it (hopefully this makes sense) and due to this, it was hard for me to see a sharp outline of Saturn or Jupiter (for Saturn, I managed to figure out the orientation of the ring due to the high reflectivity).

Is the aura normal for binocular views? Or is it that I am not focusing correctly? I tried my best to get the focus and went from one extreme to the other, just to see if I would get a better view, however at the best view, I still saw the aura (radiance).

Hope my question is coherent (no pun intended )

I have noticed this when there is very thin cloud or just lots of vapour in the air.

Hi Roger

Is there a website I could lookup to find out the current water vapour at a particular location at a particular time? Is this same as the humidity?

Thank you

possible 'fogging' on the glass? I've noticed this when i take the binos out of the house and using them straight away (especially when I'm having a smoke while viewing).

I just use me shirt to 'demist' or sit them on the table for a little while and look again.

also another possible cause could be that Jupiter is so low in the sky in the evening, atmospheric aberration perhaps?

Hi Guys

Thanks for the responses. Really appreciate your views.

I think it was more of atmospheric abberation that was causing the issue since on different days I get different views. Two days after I initially posted this thread, I was able to see Saturn much better and two nights ago, I was able to see Uranus.

It seems to happen with objects with high visual magnitudes more. All in all, it is nice to know that my eyes were not playing tricks on me
