Observation session and planetarium show conducted for the visitors.

Went to observatory and discussed about image extraction (which is in .fit format) from astroFX software of celestron telescope .
- Issues:
- No delay for the nob to rotate.
- Solution:
- Decided to take alternate photos.
Also take measurements of base platform for attachment of circuit board.
Discuss the feasibility of using Raspberry Pi instead of laptop.
- Issues:
- Not availability of AstroFx or similar software on ubuntu.
- Storage issues.
- Controlling the software for other computer on network.
- Solution:
- Decided not to use Raspberry Pi.

Servo control systems are best suited to high speed, high torque applications that involve dynamic load changes. Stepper control systems are less expensive and are optimal for applications that require low-to-medium acceleration, high holding torque, and the flexibility of open or closed loop operation.
