Uranus with the naked eye was created by johnflannery
hi folks,

succeeded in spotting Uranus with the naked eye last night. It wasn't until I got home and compared the field I was looking at that I could say it was a positive sighting.

the planet is just a few days past opposition (which it reached August 24th) and is magnitude 5.7). It within a lop-sided box of stars composed of iota, 38, 39 and 42 Aquarii.

I could see all four with 39 Aqr being the faintest at magnitude 6.05 (Sky Map Pro v.6) The planet itself is about half a degree below 38 Aqr.

it's a feat I've managed before from Zimbabwe in 2001 when the planet was much higher in the sky. I never thought it would be possible to do so from here at the moment with Aquarius being low.

tonight might be clear again so why not see if you can spot this far-flung world without optical aid. I wear corrective lenses so it's not a requirement to have eagle-eyes ... just perseverence.

draw the star field you see first before checking the planet's true position.

best of luck!

P.S. ... don't ignore sweeping the wonderful star fields and M-objects with binoculars if you are out just after dark. Some great views way down in the "deep south" at the moment with M22 and the Lagoon, Trifid, and Swan nebulae.

Haven't yet managed to see Uranus with the naked eye, but I did catch my first view of the planet last Friday night through my 80mm refractor. Viewed at x133, the planet appeared as a tiny but discernable pale-green disk - a lovely sight. I was well pleased, as I'd tried several times previously to locate the planet without success. That leaves me only 2 remaining planets - Neptune and Pluto.

I'll try to locate Uranus with the naked eye the next time I'm out a decent dark sky.

I couldnt see it with the naked eye. I could only just make out the guide star I was using to locate it (Aqr 38) at mag 5.46 last Wednesday night from Djouce. I could just make out the disk of uranus at 158x. It was also my first time to see it.

With that success I tried to get neptune. Its a lot fainter at mag 7.8. But armed with a star map was able to work out the point that shouldnt be there! No trace of a disk.

I was very happy to have for the first time seen the two planets, and especially on the night of the Mars opposition.

Cheers,

I checked both Uranus and Neptune off the list this summer, but neither with the naked eye. I found Uranus quite easily through a heavily light-polluted southern horizon. The big difficulty with it I found was checking off the star-like objects I could see through the finder and eventually finding this tiny litlle greenish disk. Neptune was even tougher and barely showed a disk if at all. In fact I'm still not totally 100% sure that I actually did see Neptune. It was just above starlike in its size and was a blue-grey colour, almost like slate.
Just one difficult little bugger to go!

Al, I presume you were using your 10" Meade at the time, which makes me wonder what size aperture you'd require to have any hope of resolving Neptune's disk. Has anyone else managed to do this, and if so, what sort of 'scope were you using?

Then Terry goes and outdoes us all. He was using a C-14 though!

2. I'm just back from a w/end in Schull, West Cork, where I spotted Pluto
(with a C-14), for the first time since the 1960's, on a fantastically clear Sat night. Also, Mars was quite nice....
