Mount Wilson Observatory: Triangulum Galaxy, or NGC598 (August 1910)

[the-maddest-robot]

Finale got around to processing the photos of M33 I had taken at the end of august. M33 is a spiral galaxy about half the size of our own galaxy and located about 2.7 million light years from earth. This galaxy has a rather high rate of star formation resulting in numerous ionised hydrogen regions (the red irregular blotches inside the galaxy), some of those being notable enough to have been included in the NGC catalogue or the IC catalogue.

NGC 588 NGC 604 (Example of some of the notable nebula in M33)

On of the first recorded observation of this galaxy was possibly done by Giovanni B. Hodierna before 1654, it was independently rediscovered by Charles Messier in 1764 who added it to his catalog (hence the name Messie 33).

information on the photo - total exposure time : 1h48 min using RGB and Ha filters - camera : ASI294 mm - telescope : Newtonian 150/600 with 0.95x coma corrector - photo edited with pixinsight

For those using PixInsight for treatment/edition, I recently discovered the scrips created by Seti Astro (https://www.setiastro.com/pjsr-scripts), Blemish-Blaster was quite useful to remove the halos from my Ha filter and What's In My Image helped with the identification of nebulas. If you had not heard those scrips, you should check them out.
