Image
Google Hangout has been a coll feature where people can do video conferencing for free and it is totally web based. I have been a regular listener of AstronomyCast who were recording their episode 236 live in a Google hangout session on 24th October 2011. It was great to be in the live recording session with Pamela Gay and Fraser Cain along with other people having interest in astronomy. The interaction session before and Q&A session after the recording was great. Here is a clip I had recorded during the session.



The topic of this episode was "Einstein was right" . Pamela and Fraser cited many evidences which tells us how accurate the predictions made by Einstein's general and special theory of relativity were  You can download the podcast mp3 here or listen in the following player. if you want to join the next recording session , you can Circle Pamela or Fraser so that they can invite you the hangout session.

Oracle Vs ICRISAT Friendly Match

Image
After a long break finally Oracle Hyderabad team were invited to ICRISAT for a friendly match inside the ICRISAT campus on 22nd October Saturday. After so much of practice at our campus nets our team was desperately looking for some practice match (even if it was on mat). We played there last year and beat them with considerable margin however they claimed that their star players were unavailable and finally we had to give them couple of our players to play from their side. That was eventually my last match in that season before I got busy in some courses in IIIT. I had ended up in a high note with a couple of wickets in the same over. This time they were ready with full strength but we had couple of our key players like Captain and Vice-Captain missing. However our line up looked on good paper with a lot of batting depth unlike other tournaments where a lot of bowlers are available and usually bowlers are seen in the bench.



ICRISAT is my second most favorite ground in Hyderabad not on…

Astrophotography with Point and Shoot Camera

I recently tried to click some celestial picture with my new Sony Cyber-Shot Hx9V. Taking snaps of stars and planets is really challenging because very less amount of light reaches us and the lights generated from earth (specially at urban locations) act as hindrance. I played around with ISO and shutter speed settings to capture enough light from stars and making the camera as sensitive as possible without letting the noise to dominate. I found for stars with half moon shining in the sky ISO 200 and 15 second exposure worked as optimum setting. If I use optical zoom, the exposure time had to be reduced further to avoid trails. For 1x zoom trails does not dominate  even at 20 second exposure but picture of sky becomes very bright with 200 ISO. and reducing ISO further (e.g 100 )is not a good idea as it makes camera less insensitive to capture such faint object. I manage to capture a aeroplane trail as foll…

Sony Cyber-Shot HX9V

Image
I recently did some search in the internet before buying my digital camera. I was looking for a compact camera with high zoom and very good video recording. I was also looking for features like long exposure and my budget was around 15,ooo INR. Finally searching a lot in www.dpreview.com and checking prices in Indian online stores  like flipkart.com , letsbuy.com and infibeam.com . I don't really trust any other site as of now. I narrowed down my search results to Nikon CoolPix S9100/S8200 , Sony Cyber-shot HX9V and Panasonic Lumix DMC-TZ20. Panasonic one was having touch screen and 60 sec shutter  exposure and 240 fps recording options advantages over the others. However from the reviews I concluded not to go for touch as one has to operate buttons also along with it and I was not sure about this brand in digital camera category. I went to the nearby store and checked Nikon  s9100 and Sony HX9V and found that optical image stabilization was way better in HX9V than S9100 and later…

Durgam Cheruvu Trek Again

Image
There was an unfinished trek of mine a couple of weeks back.Today it was time to complete it. Thanks to GHAC for giving the opportunity again. This was my 3rd trek with GHAC. The place was same, the starting point was same as well,  just the company was different and very friendly as usual.



We started at 6 AM in the morning and took a more difficult path to enter the area adjacent to the Mumbai road. We had to climb rock and bushes at the starting point itself , so we did decent amount of body warm up at the starting point. We did scrambling at the medium sized rocks which was a new experience for most of the new comers. GHAC founder Diyanat explained the difference between rock climbing and  scrambling (where only limbs are used to climb). He also said during scrambling one should always make sure that 3 of the 4 limbs are attached to rock/ground and make movement with the otherp one. Some up us also tried chimney climbing.
