Grinde

M 31 Andromeda Galaxy, 41 hours and 27megapixel mosaic

It is still one of my regular desktop backgrounds! Love it.

I’m really late to this thread, like others I don’t know how I’ve missed it especially as I am a massive fan of galaxy images.

It is quite simply the best M31 I have ever seen. One of my pet projects for when I retire and get a permenant set up is a multi panel detailed image of M31, after viewing this I will be giving it go, but I can’t see me getting anywhere near this result, it is just superb.

Time very well spent Jonas... If you are going to do an image of one of the most photographed objects in Northern skies then do it just like this. It is a very special image Jonas you have made that AG12 of yours sing. Its been said many times here but really has to be the best M31 image I've seen.... pure class!

Just catching up with the imaging section as have been snowed under and then this pops up, just simply amazing, I don't think I have ever seen an M31 as good or detailed as this and I have seen some pretty amazing M31's.

Just superb!!!! Speechless.

Holy thread revival.... 

Inspired by this I am starting on my own multi-month project on this with the TEC140 and ATIK 460.    I'm just doing luminance to start with,  15 panes  of 9 x 10 minute subs each.  Got one pain done so far.  Will add RGB 2x2 later.

This was and is a truly great image by Grinde, who is one of my robotic clients, though this image was taken from his home country. The high dynamic range makes it a very difficult target, despite its popularity and the fact that it's the easiest galaxy to see naked eye (and the only one I can see naked eye, though some can see M33.) Good for you for giving it a go. These big projects are great fun and very rewarding.

Agreed Olly (if I am qualified to agree).  I find this an extremely difficult target to process.  How bright the core?  How red the HII regions?  How bright should the arms be?  What colour balance?

Grinde's effort here takes this to another level altogether.  Masterclass.  His Schumacher to my Miss Daisy.....

It's amazing. Really useful as a reference after observing the m31 globulars visually. I looked at two in this image last night. G272 and G280.

The thing about the core is not so much how bright the bright parts are but how to get the less bright parts into play. I don't know how Jonas did it but I found that ruthless brutality worked remarkably well! :icon_mrgreen:

Wow! I somehow missed this post 5 years back. Very pleased it was resurrected, what an incredible mosaic by an amateur or a professional, well a human really!

Wishing you good weather Kirkster. I'm sure it will be something special, and I hope I catch the thread when you post your results.

Yes, the very best of luck kirkster!

Obviously profoundly good.  But I bet you can get even further into the core.  Brightness kills dynamic range.  With your dedication, taking a few shorter subs per channel should be right up your alley.  Take a look at this meager green stack.  Structures actually go right to the core (almost)  There is only a few hours of data here--unlike yours, but the structures are clear.  I am sure you can find more detail in your core.  Well done on the aquisition and processing.

What Edwin Hubble would have given for a modern astro camera - even an amateur one!

      My M31. Shot over 3 nights. Only 11 total hours. LRGB only with Astrodon filters, ZWO ASI1600MM-C camera, and the WO Redcat.

      Hey.. So last night i went to a beach that had one side completely dark ,and the other filed with light pollution . In the dark side,the milky way gqlaxy was pretty obvious and the sky was  full of stars. Andromeda was rising and i wanted to take a peak, however , it was low on the horizon and had a slight haze(skyglow).It wasn't visible with the naked eye and in my 10x50 binoculars i could just resolve the core.
      I heard Andromeda would be visible with the naked eye as its mag 3.3. But the milkyway was and Andromeda wasnt.What went wrong?

      I currently am on holiday in my father's hometown, a small island near rhodes called symi.Symj, is a pretty small town,with only about 2000 residents.That means that the light pollution levels must be low. Acknowledging that, i called my friends, grabbed my 10x50 bins(that i got for 20€ from Turkey),and went on my way to find a dark site.About after 20 mins of walking (from the city),i stumbled upon a beach, it was dark, so i went in.There i decided to lay on a sunbed that was there.After looking up(not being dark adapted, my friends just kept turning their flashlights on for some reason), i saw the haze of the milky way stretching from Cassiopeia to cygnus and beyond!I was amazed as i ve never seen the milky way before and smudged it off as clouds until i confirmed it was the milky way from an app! The weird part was that at just straight overhead, was the port ,which had many lights, and as a result the sky appeared half bright and half dark. I turned over at Sagittarius and headed over the lagoon nebula. Brilliant! 3-4 stars in a line surrounded by bright nebulosity.(while still being in the haze!) Afterwards i headed to cygnus,it was a real light show! I saw the milky way layering on top of Cygnus while catching a glimpse of m23 and yet again, failing to see NGC7000 . Then, with the corner of my eye, i detected something moving, then turned over to Cassiopeia to see a shooting stsr!(it was my first time seeing one!!!) Was very brief, yet enjoyable. Right afterwards i turned over at the Perseus double cluster.Magnificent! Appeared as 2 small balls of light , almost connected yo eachother. Finally, i realised that finally, the target i was seeking to observe all year long, M31 was into the area with the light pollution! What a shame! While also being low on the Horizon, I couldnt see it with the naked eye. I observed it with ny binoculars for 10 minutes or so . The core was resolved nicely with some hints of outer nebulosity. Overall a great night and now, i wished i had my 8" dob with me....

      Second time I undertake this kind of endeavour. Many many movies were shot. Over 300Gb of data. Stitching was done by hand. in adobe Photoshop. 
      Equipment used: 
      CFF 300f//20 cassegrain
      ASI174MM with Astronomik proplanet807
      processing using Autostakkert, lynkeos and adobe photoshop.
      Image is a wee bit too large to add to post direclty. hence just the link.

      Make sure to check out at full res.
      enjoy.

      Could be one to watch as it should brighten further... shame it is so poorly positioned at this time of year
