Jupiter in the daytime?

Forgive me if the question is utterly mad, or indeed bad, but I recall reading a post (I think on SGL & I hope I'm accurately recalling it) that mentioned viewing Jupiter in the daytime...

Is this possible?

(& no disrespect whatsoever is intended here - I simply do not know).

Thanks for any enlightenment!

Hiya, 

Mad, bad and dangerous to know . . . LOL!  :tongue:

As to your question - yes and no:

It is possible at dusk / dawn at certain times of the year, but the 'seeing' is not as good when the object is lower in the sky (too much atmosphere for the light to travel through.

Often planets are visible before stars at dusk as theirs is the reflected light off of our Sun, rather than remote stars which are dimmer because of their distance.

It's a fascinating learning curve astronomy, innit?

THIS is a very good intro to Astronomy theory. THIS is a good 'round-the-year' guide to navigating the night sky.

Thanks Myopicus (& ChrisH) :)

I lke the dangerous to know types! Good ol'Joolz. Wonder if her hair is still a Red Giant...

As for the curve, I'm realising I'm waaay down in the foothills still...

I just ordered TLAO (finally! Been on my list for months) and cheap copy of Patrick Moore's Tearbook of Astronomy 2014.

Yes - you can see it during daytime.... & I managed to take a photo (single shot rather than stacked video) of it through my 4" scope back in March....

Obviously you need to be extremely careful when viewing with respect to the its position in relation to the sun... but it's pretty easy to find and view/photo.

Cheers,

Mike

Easy to view Jupiter (and bright stars such as Polaris) during daytime with a small telescope, if you use high enough magnification and know where to look. Polaris is obviously the easiest target in this regard because it's always in the same place. Jupiter can be seen with the naked-eye in daylight, but that's a lot harder, and again you need to know exactly where to look. The simplest way is to observe Jupiter as dawn breaks, keep fixated on it as the sky brightens, and see how long you can keep it in view.

If memory serves me that was about 2pm in the afternoon on a particularly clear/sunny day back in March.  Yes - you're right - you can just about make out some of the bands :-)

That was a single shot of 1/400s @ ISO3200.   I looked on Stellarium to find whereabouts in the sky it was, then used a widefield eye-piece to find it, then moved up to a more powerful eye-piece, then added the 2x barlow, re-centereing in the FOV each time.  I didn't bother doing any kind of star-alignment (obviously - there weren't any stars visible to align against), so instead once I got it centered I set my tracking mount to "track current object" and it seemed to track it pretty well.

I have seen both Saturn and Mars in the early evening blue skies. I thought it was cool to see them when they were not visible with the naked eye and a lot more detail was visible than I was expecting. It was a kind of, I wonder if... and I could. :)

I notice that all the 'yes you can if you know where to look' comments are from posters with goto / guided systems.

Just saying. . .  :evil6:

Behave... I found both by knowing where to look and only setting up the Goto after I had something to align to.

As I said in my post - I found it manually first using Stellarium ... only once I'd found it did I then get the mount to track it.

I found Venus with with my naked eye during broad daylight on a number of occasions.

Each time the sky was deep blue and Venus was very high up.

I seem to remember accounts of people doing the same with Jupiter. Not sure I have the visual acuity to achieve that and haven't really tried. 

Maybe a project for me there... :)

I 'found' it and tracked it from 2pm one afternoon, all the way through until it got dark. I'll find the thread on it in a minute.

It's interesting to see the increasing contrast as the day goes on, even though the sky doesn't look noticeably darker.

EDIT: The reason for the quotes around found was that I used Goto. Just sayin' ;-)

Sorry...PST? :huh:

Missed this one.

PST = Personal Solar Telescope

It is a specialist scope which is designed purely for looking at the sun in the Hydrogen alpha frequency. This shows up many features such as prominences, filaments, granulation etc.

This is the entry level scope, you can spend a fortune on higher end solar kit.

Hopefully it goes without saying not to look at the sun through a normal scope, instant blindness is likely to be the result :-(.

You can use Baader Solar film to cover the front objective to show you a white light view which will reveal sunspots, granulation and faculae, makes for nice viewing.

If you are interested, make sure you educate yourself on how to do it safely. Search on the forum or ask away in another thread.
