ngc7000 in mosaic

[astropixel]

Hello Everybody

During the month of August, I finally had time to make an image of North America and the Pelican Nebula.

The object is large, I made a mosaic of 2 images with the FSQ106 and stl11k.

For each image, I used a filtre h-alpha and a exposure time of 4 hours.

The H-alpha filter works miracles in light pollution.

You can see the image in various sizes:

That has to be one of the most detailed and deep images I have ever encountered. Even with a machine with Quad Processors, 3 GB memory and a NVIDIA 8800 Ultra card it took an eternity to scroll around it at 400% :shock: .

Incredible capture Seb well done

Hello Everybody

Thanks you for your comment.

I was very surprised by the noise/signal ratio obtained in 4hr on this region. It is so deept that it is a pleasure to photograph it.

The KAi11002M gives me a lot of satisfaction. It's very pleasant to work 24 * 36.

For the little story, this picture is a little element of a bigger project mosaic

But actually I miss time to finish it. Just a little patience for the final picture (I hope it in the end of november).

its a sensor that has caught my eye too...what sensor temp do you normally image at?, and do you notice substantial noise from your subframes

Hello Paul

For this picture I work at -20°c with assistance of water. Normally I work at -25°c in rapport of the anbiant air (for this picture the air temp was about 13°c).

With addition of cooling with water I win -5°c.

About the ratio signal/noise I find it very well with single exposure time of 20min.

Absolutely fantastic image. Really enjoyed just scrolling around it. The tiny little Pelican neb gives one a great idea of the scale of this beast.

You should be very pleased with yourself.
