21/12/12 – an interesting sighting

So, Doomsday, couldn’t miss out on that, could I?
Yeah, i know it’s a bit out of date – but anyway…I’ve got an interesting sighting (for myself at least).

Always, Jupiter’s orange bands lie almost horizontal when seen through my scope. Sometimes, they’re in line (on the same plane) with Jupiter’s moons.

But around 11pm, on the 21st December 2012…(ta da da)

The bands were almost vertical.
But Jupiter’s 4 biggest moons, were scattered about the usual horizontal plane.

I had to make a sketch of it. And as soon as I get it scanned, I’d post it.

So, take a look at the sketch and let me know what you think.
Perhaps it’s got something to do with Jupiter’s speedy rotation (one rotation takes 9.9 hours) or tilt-too-much of its axis (if that ever happens).

So intriguing.

Do enlighten me, if you can.

Clear Skies!

This slideshow requires JavaScript.

It’s 4 AM and Jupiter, Mars, and Orion are right above my balcony. Whatta treat!!

Been such a long time since we’ve had clear skies and when it was clear last night, I just had to take the Dob out! – despite loosing much sleep…with upcoming exams, oh noo!

Btw, Jupiter doesn’t look nearly like the picture I took…after 1/2 and hour struggling to get (and focus) it into the field of view of the camera. You’ll actually be able to see its orange rings with a 24mm Plossl, and swirls on it with a 10 mm Plossl eyepiece! Mars was orange as usual. And the Nebula with its Trapezium, frozen in time. Bout time I get some filters – for some colour with the nebula and for better definition of the Great Red Spot. And I reallyyyy wanna see the Horsehead nebula on Orion!

Any thoughts on good filters? I’m thinking Baader’s Moon and SkyGlow filter – seems like a good all around filter for both sodium vapour wavelengths (light pollution) and for contrast.

Clear skies!

Jupiter Watch

Last year, when I first bought my scope,  I didn’t realize how much weather conditions affected observing. And so I thought I would be up stargazing every night, recording and collecting my observations to make my own deductions.  But, the haze (swept from Indonesian peat fires) and rain clouds in Malaysia has severely limited my observation nights instead…Darn you weather!

But,  last year,  there was a week with two clear nights (a rare event from my home). It happened when the monsoon rains cleared sometime in October. And guess what, Jupiter was up. It was the first planet I ever saw in real!

Here’s My sketches of Jupiter. I used a 24mm and 10mm Skywatcher Plossl to view the gas giant. Check it out! To the naked eye, it appeared as the brightest star in the sky. And I was lucky enough to catch all four of it moons on one night!

Jupiter season should be back soon, can’t wait. I’m praying the skies will finally clear up by then!

 

 

Have you seen Jupiter? I’ve been saving for a set of planetary eyepieces –  I really want to get a better view of Jupiter’s Great Red Spot.

If you’re from the tropics, what’s the weather like there? Similar to Malaysia?
