SUMMARY
The discussion confirms that interstellar extinction does not alter the observed angular size of star clusters. While dust makes stars appear dimmer and alters their observed color, it does not affect the angular size measurement of a star cluster located 100 parsecs away. This conclusion is based on the assumption of a smooth distribution of dust, which influences brightness but not angular dimensions.
