Treasures of Cygnus

I'm still waiting for an astronomical darkness to come, up here 65N. One of the best targets for astronomical imagers in Autumn sky is the nebula complex in constellation Cygnus. That'll be my first imaging target in this Autumn as well. I'll be able to shoot it around mid September.

The collection

I made a collection out of my Cygnus images. Pictures are taken between 2007-2013 with different instruments. Closeups are taken with my longer focal length instrument, an old Meade LX200 12" telescope. Wider field images are taken by using two camera lenses, Tokina AT-X 300 f2.8 and Canon EF 200mm f1.8 lens, both full open. All images are shot with QHY9 astronomical camera and the Baader narrowband filter set, H-alpha, Oxygen and Sulfur.

Note. a large image, ~7MB

A collection of my images of constellation Cygnus. Photos are shot between 2007-2013.
The top most image is a large 18-panels mosaic of Cygnus, it spans 22x14 degrees of sky! (An apparent size of the full Moon fits in this area over 1200 times.)  At middle, there are images of individual objects. All but the Veil nebula supernova remnant, can be seen in top most image.
At the bottom , there is a single panoramic image of "Cirrus of Cygnus", it's from the top part of the large mosaic at a top. I added it as an individual image, since it's full of very dim filaments of gas, the formation is over 1000 light years long. I haven't seen a separate color image of this are before.

Technical data and other information

You will found all the images in this collection from my portfolio with technical details.

I have published this image at Autumn 2012, more info in this blog post:

The Cygnus mosaic
Note. A large image 2200x1400 pixels and ~5MB.

The large mosaic of constellation Cygnus covers 22x14 degrees of sky. Total exposure time with QHY9 astrocam and Baader narrowband filters is ~120h.

The large panorama of Cygnus looks very much like a "Chinese Dragon"!

A two frame mosaic image, from Butterfly to the Crescent Nebula

I'm posting this older photo, since it hasn't been posted as an individual image before.
This is a two frame mosaic from the constellation Cygnus, showing the Butterfly and Crescent Nebulae. Image is shot at Nov. 18. 2011.
This image is part of a much large, 18-panel, mosaic of the constellation Cygnus.

An experimental 3D-study of NGC 1499, the California Nebula

This is an experimental test with a 3D-conversion of my astronomical images. Only real elements from my original image are used, there is nothing added but the volumetric information!

NOTE. This is a personal vision about shapes and volumes, based on some scientific data and an artistic impression.

Art ∩ Science = Wonder

My summer pause is still ongoing, next time we'll have an astronomical darkness at mid September, up here at 65N.

Astronomical imaging is a mixture of art, science and technique. The art part is the most important for me, even though my images are scientifically correct. I made an image to show, how I see my passion.
