NGC 2489 is a young open cluster in the constellation of Puppis, situated in the southern hemisphere and is said to be visible with a small telescope. This cluster was discovered in 1785 by William Herschel.

NGC 2489 is ~19 light years away and is estimated to be 18.4 million years old.

I couldn’t find much research on this cluster but one paper stated it was bright enough for spectroscopy could be carried out to view the membership and rotation.

In order to study NGC2489 and investigate the relationships between the colours, brightnesses, and the age and chemical composition of the cluster as a whole, I collected 15 images in B,V,R filters with certain telescopes, with total exposure durations of 130.65, 66.13 and 50.0 seconds in these filters, with other imaging parameters, using Skynet. I used Afterglow and Cluster Astromancer for their purposes. And I found these basic results about 2.01kpc in distance, proper motion RA: -2.53 mas/yr, proper motion Dec: 2.17 mas/yr.

I did this to learn and view the true image of the cluster. There are quite a few very white/blue stars which makes sense since this is a young cluster but also a few yellowish stars which is nice to see some variance. I noticed a couple blue stragglers and learned that they make their way into some of these photos which can influence the age we calculate if not studied closely. I learned that my cluster had ~279 stars in it which seems fairly small compared to the other examples I had worked with but didn’t have many issues it felt very straight forward.

 

I had plotted the data with:

Estimated Proper Motion RA: -2.53 mas/yr

Estimated Proper Motion Dec: 2.17  mas/yr

Distance: 2.01 kpc

Log Age: 7.75 log(yrs)

Age: 56.23 (Myrs)

Metallicity: -0.25 (solar)

Reddening: 0.64 (mag)

Overall, this was the best section of Astr 113, as I got to directly involve myself with a new and interesting piece of the sky that was quite beautiful.
