Wonders of Gemini
The collection
I made a collection out of my images from the constellation Gemini. 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.

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.

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.

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.

Pelican Nebula zoom in series and the scale in a sky
I have shot many targets with several focal lengths. Due to that, I will publish some of my material as image sets, with a different field of view and level of details. The fractal nature of our universe stands out nicely in this way and it will make the orientation more easy.
Many times, it's difficult to understand the image scale of astronomical images.
Therefore I have added a "Moon circle" in the images to show the angular scale in the sky. The full Moon has an angular size of ~30 arc minutes, that's equal to ~0,5 degrees.
Be sure to click for a full size image!
Note. a circle, size of the full moon, as a scale.

Filaments of the Veil nebula, starless view
One of my starless astronomical image experiences, the Pickering's Triangle in Cygnus supernova remnant.
This area of the nebula is filled with colorful filaments, ionized sulfur and hydrogen are seen as green, golden hues, ionized oxygen can be seen as blue.
The complexity of filaments stands out nicely in this starless image.
An original image with the stars
Image is in mapped colors, from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.

Area of interest is marked as a white rectangle, the apparent size of the Moon can be seen at lower right corner.
INFO
Pickering's Triangle, Simeis 3-188, is a small part of the Veil Nebula supernova remnant in constellation Cygnus.
Veil Nebula is a cloud of ionized gas and dust, leftovers from an exploded star. The star went off some 5000-8000 years ago at distance of about 1470 light years. This, relatively faint target, is difficult to image due to the large angular diameter, about three degrees, and a dense star field.
Exposure and processing details
Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack2.
Levels, curves and color combine in PS CS3.
Optics, Meade LX200 GPS 12" @ f5
Camera, QHY9
Guiding, SXV-AO, an active optics unit, and Lodestar guide camera 8Hz
Image Scale, ~0,8 arc-seconds/pixel
15 x 1200s exposures for the H-alpha, emission of ionized Hydrogen = 5h
9 x 1200s exposures for the O-III, emission of ionized Oxygen = 3h
4x1200s exposures for the S-II, emission of ionized Sulfur = 1h 20min.

An experimental starless version of the Wizard nebula,
I like to make starless versions of my astronomical images now and then. They'll show the actual nebula better and have a kind of mystique feel.
Human brains has a tendency to form some quasi logical shapes out of cloud of random dots, like stars in this case. Without stars, the shapes in a gas cloud stands out much better.

INFO
The "Heart Nebula", IC1805 locates about 7500 light years away in constellation Cassiopeia. This is an emission nebula showing glow of ionized elements in a gas cloud and some darker dust lanes.
In a very center of the nebula, lays Melotte 15, it contains few very bright stars, nearly 50 times mass of our Sun, and many dim ones. The solar wind, a radiation pressure, from massive stars makes the gas twist to a various shapes.
