Log of events:
| Time | Activity | Remarks |
| 18:30 | All instruments taken on the terrace in two batches | |
| 18:45 | All instruments placed on the observing terrace | |
| 18:50 | Begin assembling the tripod stand, EQ-3 and the optical tube. | |
| 19:04 | R.A. Motor connected and telescope polar aligned | New batteries would be needed soon. |
| 19:06 | Sunset | |
| 19:15 | DSLR attached to the telescope and appropriate balancing of counter-weights done. | Today it did take quite some time to get the balancing perfect. With a 2x converter connected it can get difficult. |
| 19:35 | System properly balanced. | Oiling of joints may be needed |
| 19:40 | First attempt at controlling the DSLR
Using the laptop and Digicam control software. I began observing the moon and this time since the controls were with the computer only wind vibrations were affecting the image stability. |

| 19:40
-20:45 |
Kept taking successive videos of the Moon using the 2x Barlow converter and focused on a particular region of interest with a small crater. Winds on the 12th floor are harsh and being prepared with all necessary precautions
Proved to be helpful. With a 2x Barlow Moon drifts quickly if the polar alignment is wrong. Images on the laptop looked well focused for a 2x converter. |
The elbow became lose at some points with the 2x ON it. |
| 20:45 – 21:35 | Observed Venus, Jupiter and Saturn. The phase of Venus looked very apparent with the help of 2x converter. Jupiter’s bands and Moons were visible as well except that it is a much better view with an eyepiece. | |
| 21:35 to 22:00 | Tried hard to observe M51 as the city sky was quite light polluted. Didn’t attempt to photograph it using the DSLR as the elbow was having some issues. The Meade finder scope proved to be helpful with the star just at the center of the cross-hair and subsequently in the eye piece. M51 is just a small spec of dust from here. | |
| 22:00- 22:30 | Observed Saturn once again. Fixed the balancing issue of the counter weights to ensure smooth functioning.
Skies are beginning to get cloudy. |
|
| 22:30 –
22:45 |
Dinner break | |
| 22:50 – 23:30 | Just observed the moon and its craters along the terminator. Absolute visual treat. Final summary of what all went right and wrong today was also done. | |
| 23:30- 00:00 | Pack up and closing of the instruments. | |
| 00:05 – 1:00 | Data transfer to laptop and conversion of .MOV files to .AVI using Virtual Dub. |
