    Don't know exactly how many squares there are in your pic but multiply by 100 billion or so (average no of stars per galaxy) and you have to believe that "someone else" out there is a distinct possibility! Same question - or similar - posed here.

    Just to the left of Wezen in my pic of Canis Major above, there's a corona like grouping of stars. Thought I'd share a couple of pics of other 'coronas' namely Corona Australis close to the tail of Scorpius and Corona Borealis just below the Bootes constellation. Corona Borealis - I understand...

    Thanks for the heads up - was a bit late seeing it unfortunately. You snooze, you lose!

    Great pics - did you or anyone out there try taking a pic with a diffraction grating lens ? Should get an excellent solar spectrum!

    Closer to "home" albeit not much more than a 'holiday snap' , here is a portion of the Milky Way on a clear Highveld night. 2024/03/20 / 03:47:12

    I Question on Lambert W function

    Hi again: Re: ##P - \dfrac{M}{r} \left ( 1 - e^{-Tr} \right ) = 0## This solves for per period interest rate in a continuous amortization process where T is number of periods, M is per period payment and P is loan amount. We have seen in this thread that the solution to the equation invokes...

    The last "faint smudge" I found on one of my pics turned out to be 10 million stars in a (possibly) collapsed galaxy. As a child, the family had a wonderful dog called "Smudgie" so I guess that's where doggy heaven must be :wink: (Caldwell 80!).

    You can see Betelgeuse is slightly 'orange' so I guess the camera's 'eye' might show that too. Come to think of it, the obvious way to check out the red blobs is to take multiple photos rather than just one and then see if the red spots are in the same place or just randomly distributed. Will...

    Some more red dots in same pic. Bright star is a Crux and one of the red dots is right next to binary system labelled Theta Crux in Stellarium. Zoomed in on the right.

    Thanks for your thoughts on the mysterious red dot(s). I also found both items you mention in Stellarium but the locations did not seem quite correct. However if I zoom in on Betelgeuse (old star in Orion) , it has a red/orange pixellated fringe whilst Rigel (young star in Orion) has a blueish...

    Thanks. I had a careful look in Stellarium and also couldn't find anything that would relate to the red spot. But there are quite a few of them if I zoom in on the pic. Some kind of camera artefact perhaps. Red is lower frequency radiation - older stars ? Or something moving away (red...

    Faint "smudged" looking star left top directly above Beta Centauri (rightmost Pointer) is Omega Centauri - a very large cluster of stars or possible dwarf galaxy since a black hole was detected at its centre. https://www.esa.int/Science_Exploration/Space_Science/Black_hole_found_in_Omega_Centauri
