Simulation A:

• 1 Diameter 600 mm
• 2 Focal Length 1800 mm
• 3 F/D Ratio 3
• 4 Eyepieces 30 m
• 5 Barlow? N
• 6 Celestial Sights M42 - M31 - M51

Simulation B:

• 1 Diameter 150 mm
• 2 Focal Length 1800 mm
• 3 F/D Ratio 12
• 4 Eyepieces 30 m
• 5 Barlow? N
• 6 Celestial Sights M42 - M31 - M51

Q7: What appears to be the difference between images in Simulation A and Simulation B, and what do you think is causing this?

Q8: If you were trying to measure the size of the Whirlpool galaxy, do you think your choice of telescope would have an impact on your result? Why or why not, and if why then in what way?
