M31 The Andromeda Galaxy

: M31 The Andromeda Galaxy; Here is another attempt of the Andromeda Galaxy taken with my 30d and a 70x200L lense on my telescope drive mount. It is a composite of 12 shots at ISOs from 400 to 1250 and a total exposure time of 31 minutes. Thanks for looking.

Thanks Jas, Alex, Art, Zoya, Carol, Alan, Ikka and Steve! Steve, I used the DeepSkyStacker program on this one. It is quite a neat program and free. I also did do some tweeking in Arcsoft, the photo shop that came with the camera. Just some light tone, contrast and saturation adjustments. Thanks again everyone. Don

Great shot! What stacking software do you use? Any cleanup done in PS?

Hi Don, fantastic, this image is so wonderfully taken, best of...

maybe you can write/inform me, which lenses etc. you had been used.

Ciao Ikka

What a awesome view!! and really fun to look at. You are the King Mad Scientist for sure... How you put all the photos together and not having any star trails from all of the exposures is amazing.

Well, 'Mr Mad Scientist', your 'playing around' certainly produced the most wonderful image for us all to see; it's awesome! How you got there sounds all too complicated for my poor brain to cope with but I definitely like the end result. :)

Thanks Alandra and Alex!

Alex, I'm really captivated by the night sky and all there is to see. M31 can be seen with the naked eye as a fuzzy spot just to the right of Cassiopeia. And while the core is fairly bright, it is difficult to pull detail for the dim outer edges without stacking photos. The limit to exposure time is light pollution and the ability to stay tracked, if the shutter stays open too long you get LP fog and/or star trails. This is the reason for the composite of stacked shots. It is odd I guess, to use mixed ISOs, just something I have been experimenting with. In my mind, I can gather more detail with the lower ISOs and more object brightness with the higher ISOs. Combined together you get the best of both and it seems to work. On the other hand, stacking a number of set ISO shots, say ISO 800 would give you very close to the same results. I just like to play around like some sort of mad scientist, lol. Don

Sounds like this took you a lot of work to put together. This came out great. I am really impressed. I have never heard of creating a composite with different ISOs. Perhaps you would share with me/us why a composite was necessary and how you put it together.

very impressive, Don. Really like it.
