Andy Resnick said:Some images from last weekend (Pleiades and Orion): all taken at 400mm,
davenn said:just some thoughts ...
I will note that particularly with the Pleiades and the Flame/HH images, I am surprised you haven't captured much more light for 2.5 hours of total exposure ??
You didn't comment on camera or ISO settings ? ...
I wonder if you are using a very low ISO and or the camera is an older one with a less sensitive sensor chip ?
For 2.5 hrs exposure time, the nebulosity around the Pleiades should be so brightDave

awesome idea ... label the thread " astro image stacking" or words to that effectAndy Resnick said:If there is interest, I could open a new thread and walk through the entire process, maybe you (or anyone!) have a useful suggestion.
Awesome photo!Andy Resnick said:First is a full-frame
I actually prefer the first one to the second one. I think it's nice to see the vast surroundings of the constellationAndy Resnick said:the second a more pleasing crop

It looks like it could be a good desktop wallpaper too (if it's turned + or -90°).
You don't have a flickr account? For uploading images in large resolutions?
See e.g. this thread: https://www.physicsforums.com/threads/best-online-free-photo-storage-option.947054/
and e.g. my post #5.
I understand.Andy Resnick said:A colleague of mine, who teaches photography, has very definite ideas about how 'freely shared photos' has wrecked the profession
Hi you and a happy new yearbruha said:I just attach my most well-done image of moon up to know- right down is Copernicus I think and right darker elipse is plato (dont know name).

Can you tell me from which place you made it (probably absolutely without light noise..?) and which devices you use?
Lot of success and happy new year …..![]()
