RE: Cliff Hanger Mk II - Astro Photography
Thanks so much.
With this image i have taken 15 separate exposures for both the sky and the foreground. 15 with the sky in focus and 15 with the foreground in focus. The reason i take so many is because i stack them together to reduce overall noise in the images from shooting at a higher ISO. I then Blend the sky and foreground images together and Whala! A crisp clean image with both the foreground and sky in focus. :)
And yes both manual focus
if i shot 15 in foreground pic + 15 pic in background in same place at night photographywith 20 sec for each pic... would it be supposed to have slight "star trail" effect on the star?? how did you remove the "star trail" effect while you can maintain the perfect exposure for the background during editing?
Look up a technique called "exposure stacking for noise reduction". You can learn all about it.
But basically one of the steps is to align all of the sky layers. That way you get pin sharp stars :)
