Jupiter and Neptune
      #3135381 - 05/30/09 07:18 AM

Hi Folks,

I made this quick widefield sketch of Jupiter and Neptune this morning and posted it in the Planetary Observing forum. The two planets have an angular separation of only ~25 arcminutes, so it is a rare opportunity to easily confirm a sighting of Neptune (mag 7.9), since the King is blazing away right next to it.

I made the sketch with a 2B pencil and inverted it digitally after scanning.

Michael,

Very impressive sketch. I did not realize that they were so close in the sky. I don't think about looking for Neptune until late summer. I should get out there one morning before sun up and have a look for myself. Thank you for posting this.

Michael,

An excellent low power observation showing Jupiter (and it's satellites) and Neptune in the same field. It must been exciting to think that you experienced a view similar to Galileo's long ago. Thank you for sharing it with us all.

The famous Italian astronomer Galileo Galilei (1564-1642) is believed to have observed Neptune in the same field of view as Jupiter on the night of December 27, 1612. Jupiter and Neptune at that time were separated by 16.5 arc-minutes. The typical Galilean telescope employed a plano-convex objective focal length between 30-40 inches and stopped down between 0.5-1.0 inches), a plano-concave ocular with a focal length of 2 inches. Galileo typically used magnifications between 15-20x for his observations (he may have used up to 32x but such an instrument would have proved too shaky with a small field). All of these facts make his monumental observations all the more impressive.

An image below from Starry Night which shows the positions of Jupiter and Neptune on the night of December 27, 1612.

Mike,

Wow, I wish I just felt better as this would have been a wonderful sight to see in the early morning hours. Thanks for posting your sketch, it captures the image of Jupiter, the satellites and Neptune in really nice detail in terms of location. Nice bands on Jupiter as well.

Thanks,

Jay

Frank, Carlos, Roland, Jay--thank you very much.

Carlos, thanks for posting the informative links and graphic.

Frank, I think Neptune and Jupiter are going to have a couple more close encounters later this summer, iirc. I'll have to check for the details.

Michael,

Yes I see July 9th is the next pairing and 5th mag.Mu Cap. will be between them.

Michael,

Excellent capture of a very special event!

I guess I've never seen two planets in the same field of view.

Thanks, Rony. It's not too late to see the pair in the same FOV--your 4" scope should give you a good view. The hard part is getting up at 4 AM.

I'll be getting home from job #2 (where I lie to people for a living) at about 3am CDT. If it's clear I'm pulling out the scope. I've NEVER seen Neptune and am stoked for the experience.

Very nice sketch! Thanks for posting and reminding us. I have not seen two planets together in the same FOV for some time. Cannot remember that last pairing now a few years ago but Uranus and Neptune were very close together in the same FOV in (I think) 1988 or there abouts.

For those who have not seen Uranus or Neptune, I seem to remember Uranus as a pale Kahki green disc at only 3 or 4 arc seconds diameter with a couple faint moons. Neptune is much smaller at only a couple or less arc seconds and appears as a pale blue dot.

Thanks also to Carlos for posting the links.

Mark

Thanks, Dee, Mark, T5. Hope you all get a look this summer since Jupiter's retrograde motion will keep it in the vicinity of Neptune.

Chris, let us know if you are successful seeing Neptune.
