| Summary: | The image of the globular cluster was captured using the 14 inch Celestron Telescope. The globular cluster is a collection of spherical component stars which its look like a globes with a dense concentration of stars at their centres. The globular cluster that was successful imaged is M22. This image was captured using green and the clear filters. The aperture photometry was used to determine the instrumental magnitude of stars in M22 for both filters. The scale used to represent the star's brightness is magnitude. Bright stars have a very low magnitude. This research is done with the objective to determine the correlation between the instrumental magnitude of M22 using the green and clear filters. The instrumental magnitude from clear filter is lower than instrumental magnitude from green filter. The differences in instrumental magnitude of the stars between this two filters showed that there are almost constant although using different filters. |
