- The Home Observatory is open and gathering data every chance I get. While waiting for new projects to be completed I process existing data and it is time to show you Messier 45 or the Pleiades. I also thought it would be fun to compare my new image to an image I made 2 years ago as one of my first objects, using my Canon 60D DSLR OSC camera.
Messier 45, the Pleiades or the Seven Sisters, is an open star cluster in the constellation Taurus. It is the closest Messier object to Earth and also the most obvious star cluster to the naked eye in the starry sky. The cluster consists of over 1,000 confirmed objects and has an estimated mass of about 800 times that of our Sun. It is dominated by hot blue luminous stars that have formed in the last 100 million years but is estimated to consist of up to 25% brown dwarfs despite contributing only less than 2% of the mass. A brown dwarf is an object with less than 8% of the mass of our Sun and not heavy enough to start a nuclear reaction to become a true star.
Data for this image: 31x120s L, 12x300s L, 31x120s R, 31x120s G, 41x120s B.
Total number of exposures 146 with a total integration time of 5.4 hours.
Processing: PixInsight with LRGB palette with LRGB stars.

Looking good my friend that rolling roof is pretty cool! Nice result and comparison
Thank you so much!
Looks like mono is the way to go
Plus learning processing techniques
Thanks for the comparison
I’m in northern England and the cloud cover is insane 😂
Thank you for watching! Yes, when you go mono you never go back I would say, but then again there are instances when color is nice. But equipment is very expensive today and it's hard to have one of each.
I'm glad TH-cam decided to suggest your channel to me. I checked out your website, and just subscribed on TH-cam!
Usually TH-cam totally misses the mark for me, and suggests some low quality, AI-generated "content" (which is a very generous word to describe that kind of stuff to say the least) that I want nothing to do with. So I'm very glad I found you this time instead!!!
Thank you so much, this made my evening!
@@frosthastrophotography Aww, you're welcome! Anytime :)
That’s a beautiful photo! Would love to see a video on how you combine your LRGB, if you don’t have one already? :)
Thank you my friend! The actual combining was just with LRGBCombination in PixInsight and there select the 4 master light frames :)
@@frosthastrophotography I see! Need to learn that program at some point :)
