Earthshine

During the moons crescent phase, you can see a pale glow on the unlit part of the moon which is actually the light reflected by the Earth hence the term. So go out and have and take a peak of this treat tonight! No telescope required.

Venus Jupiter Conjunction

 Conjunction is a phenomena when two or more celestial body appear to be close in the sky. Here in this photo of the recent planetary conjunction of Venus(left) and Jupiter is at their closest taken July 1,2015. 

 

 


Crux

 Crux or the Southern Cross is probably the most popular constellation in Australia and is as well a symbol in their flag. In the southern hemisphere, it is used to approximate then location of the south celestial pole by extending it 4 1/2 times to where it points. In one aboriginal culture, it is regarded as a stingray.

Last Transit of our Lifetime.

One of the reasons why the transit was very much anticipated, observed and documented  is its rarity. In fact the next one won’t happen till the next century, not within our lifetime. Things could be very different by that time, whatever that is, what is important is to keep the passion of Astronomy passed on to the next generation, we can never tell where the science can lead them to.

Here is a short article of the event written by my student:

Last June 6, 2012, we went to Manila Observatory at the Ateneo de Manila to see a very rarephenomenon: it is the “Venus Transit”. Venus Transit or Transit of Venus happens when the planet Venus passes directly between Sun and Earth. What is special about this phenomenon is that it occurs in a pattern that repeats with pairs of transits eight years apart separated by long gap of 105 years. Apparently, the last transit occurred last June 6 and the prior to that was last June 8, 2004. It is expected that the next appearance of Venus Transit will beon December 10–11, 2117, and in December 2125.

The planet Venus appeared to be very small and very dark. It actually looked like just one of the sunspots of the Sun and every minute the Venus moved around the face of the Sun.  We are able to observe this by using telescopes. We are given so much chance to look on different telescopes that are settled up. Different telescope gave us different colours and perspectiveswith the on-going transit.Seeing the Venus Transit was one of the things that we enjoyed for staying there for almost 9 hours.

The whole experience was extremely fun,though it was from the morning until the afternoon which was very tiring. We also had a chance to have a small talk with Sir Edmond. From that short time talk, we gained so much knowledge about the transit and other phenomena that are happening inside and outside the Earth. We are so much honoured in meeting and talking with him. And of course, we are also thankful to the persons behind this event for giving us opportunity to witness this extraordinary event.

Seeing the marker of the capsule makes think If I could still see it by then, but..

..let’s keep on passing the light of the stars till then.


Feeding Mosquitoes

Yep, figuratively and literally those little insects feast on both of my chicken pox infested legs last night while I was trying to image Mars. I hope they did suck out the varicella virus as well.

I hope to get well soon, I am certainly missing a lot already.     T_T


Aperture Kills

I was able to get my hands on a 12 inch dobs of a Manila Cathedral School for their  star gazing activity.  Such a big telescope gives well detail on objects. I tried it and imaged Mars and Saturn using my webcam, but oh boy it was neck breaking  just to target the planets on the screen! But the pain is paid of the pleasure of the images produced from the 4 second clip I managed to capture.

The northern polar cap is now prominent

More detail present in this image, Cassini division, bands etc.


Friday, Saturnday

Saturn undoubtedly is a majestic planet, it always such a fascinating object on the eyepiece that you won’t be surprised that Galileo thought of it as an ear. I’m trying to work on to have the best possible detail on this planet. For now, this is  what I can offer.

Hello Mars!

Finally I was able to capture Mars for the first time. I’m trying to convince myself that I see those surface features and its polar cap. I’ll use barlow lens on my next attempt.

this tiny red dot is actually Mars.


Wednesday, Saturnday

I was hoping to image Mars earlier this morning but my location does not permit me to do so,  instead I tried imaging Saturn.  No tracking / motor mount was used to capture this image.
