Cr 69

The cluster is located in the head of the hunter, the brightest star in this small group is Lambda Orionis (Meissa).

I have analyzed the spectrum of this HII ionized region. In this graph I have looked at which were the highest peaks, to identify what element it is made of. Then I have calculated the area of ​​each peak with respect to the total and these are my results.

To show that these are the correct elements I will attach some photos. To find what each element is, I have used the following web page:

              HYDROGEN                               SILICON                                  TITANIUM                          CHROME

I have searched scientific articles and according to Siva Nagi ReddyInturi, MakramSuidan, Panagiotis G.Smirniotis, 2015 this open cluster contains silicon, chrome and titanium.
