Toa Payoh Park observing session (14/3)

Post by harlequin2902 »

After days of seemingly endless raining, there was a chance for a potentially good evening for observing yesterday. So, motivated by Zong Yao, I decided to bring out the MN56 for a run at the park. I sent out some last minute SMS notifications, and including myself, there were a total of 5 Singastro members present (the highest concentration of Singastro members in Toa Payoh area in a single observing session so far :D ). It was a night not to be wasted !

The entire sky was very clear when we arrived. Canis Major, Orion, Auriga, parts of Carina and Puppis and a few other easily recognizable constellations could be seen in their entirety (Singapore standard). However, barely an hour into our session, huge clouds came in from the East and covered most of the sky ! :( We were left with Jupiter, Saturn, M41 and M42 (i.e the "usual stuff") for the next hour through the occasional gaps in the clouds. Jupiter was at a nice height (and very bright !) while we were there and a lot of surface detail could be observed. For example, instead of seeing the usual 4 pretty obvious bands (2 equatorial, 2 polar), we could see numerous fine, thin lines (banding) near the northern polar region.

Zong Yao and I stayed on after the rest left, and we were rewarded with almost an hour's worth of totally cloud free skies from 12am. With the clouds gone from the area, the Southern sky began to come alive with all it's Southern treasures. Other than a rising Centaurus and Crux, we could also see everything between Crux, the false cross and all the way to a setting Canis Major and Orion in the West. Without wasting any time, we went on to observe The Jewel Box Cluster, Omega Centauri, the Eta Carina Nebula region, NGC 3532 and NGC 3293. We noted that NGC 3293 appeared to have a nice visual 3D effect through the 24mm Panoptic. Those observing NGC 3293 next time should look hard at this cluster too, to see if you can experience the same 3D effect like we did. We used a magnification of ~ 40x.

2 "first-time" objects for the MN56 observed this evening since it's arrival were :

M93 - an open cluster in Puppis, almost triangular in shape resembling the Jewel Box Cluster but richer.

M68 - This is supposed to be one of the known, richly packed globular clusters in the sky. But maybe because of the lights in Toa Payoh, we had a hard time looking for it. A lot of time was spent searching for it ... comparing views through the 50mm finder, the eyepiece and through the red dot finder. Finally, after some trial and error, Zong Yao managed to nail it through the 24mm Pan. It was really faint. You had to jiggle and move the scope a little to confirm it was there.

By 1am, and after one final look at NGC 3532, we packed up and headed home. The next time I'm there, I plan to do all the open clusters in the Crux region.

Here are a couple of pictures captured from yesterday to add some colour to the post :D :

Hi Samuel,

I was really surprised at the view of NGC3293 and yes, I think I did observe your 3D effect. At 48x, it really looked like, dare I say, a spherical ball of stars. It seems that this is because the fainter stars were just on the edge of clear visibility, and when they resolve into points of light, the brighter stars seem to lose focus - giving the 3D effect. Really beautiful..

Yes, NGC 3293 is nice. I actually first "discovered" it by accident while looking for NGC 3532 with the Pronto somewhere else in Toa Payoh in early '03. Since then, this has always been a must-see object for me whenever Carina is up in the sky.

Speaking of "discovering" objects by accident, I now remember that Soon Yen, Zong Yao and myself came across another compact and interesting looking open cluster yesterday while looking for something else ... but now I can't remember the catalogue number and position (and I also can't remember what we were originally looking for) ! I was so engrossed with it that I forgot to look up the charts to check what it was. Darn... :?

Soon Yen, Zong Yao : Do any of you remember ?

hi sam
seems like everyone have been having a really good time with the clear skies after the rain. in your report, you did not mention who and what scope was present but I assumed there was your MN56 and the new MegrezII?
How did your new mount performed as compared with your old one?
Also, were you referring to Toa Payoh park? Is it available already?

Looks like I will have to take a look at NGC3293 judging from the enthusiasm over it...:-)

Hi Rich,

Other than myself, Richard Low, Soon Yen, Zong Yao and Chang Chern were there too. The Megrez you see belongs to Richard. It's the original SD version. Not the 'II'.

Yes, we were at Toa Payoh Park. There are still some works going on in the park, but my usual observing site (the empty space near the observing tower) is still untouched.

I am using the Giro-2 DX, so it's nothing new actually. You've seen it before too. At least with it, I can move away from the usual heavily light polluted area outside the library at Central. The HEQ5 steel tripod legs I'm using does add some weight to the entire setup, but overall it's still much more portable than my ex-mount, the GP. Oh, I've also added some foam padding around the legs (bought from Cathay), so I can now carry it comfortably on my shoulder :D

On NGC 3293, use ~ 40x - 50x magnification and make sure your eyes are completely shielded from any stray light in your area. If you do spend a few minutes at the eyepiece studying and really looking "into" it, you may also experience this 3D effect we've been talking about.

mmm..at x 50, I would have to use a 29mm eyepiece.
The closest I have is 26mm but as far as I can remember, 26mm normally yields very wide views. Are you sure I will be able to see it at this magnification? looks like I will have to try it sometime...
