Description

A special request from Marek

This is an image made by combining 128 sub images from 85 amateur astronomers into one final image (Crowd Image). It is very high resolution (48 Mpix), so it is best viewed in full resolution.

Exposure is an estimate based on an average sample of 50 images. A separate stack of the 44 sharpest sub images were used to enhance details in the brighter areas of the image.

An interesting thing: I tried to estimate the total aperture of all the telescopes used here. It resembles that of an 80" telescope! With an average exposure time of 3.4 hours that gathers a lot of light.

For more info on Crowd Images, look at the other examples in my gallery.
