A collection of images from a large mosaic of Cygnus


I haven't been able to open up this season yet, since some of my equipment are not yet back from the factory service. (Should be here any day now!) To keep up my processing skills, I have reprocessed my older material.

All images are reprocessed and fine tuned. Images are shot wit a Canon EF 200mm f1.8 monster lens.
This lens is very sharp from edge to edge at full open. 
Some parts of the mosaic are boosted with longer focal length instruments, Tokina AT-X 300mm camera lens and the Meade LX200 12" SCT-telescope. QHY9, a cooled astronomical camera, is used with all instruments. All photos are in narrowband colors, from an emission of ionized elements, Hydrogen, Oxygen and Sulfur. Baader narrowband filter set is used for the emission line imaging with all the instruments.

Reprocessed, NOTE. a large image 2300 pixels wide and 4.3MB

Image is in mapped colors from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen. Native size of  this image is over 15.000 x 10.000 pixels.

Please, pay attention to a resolution of images bellow. I have used a new processing technique of mine to keep images sharp during the processing routine.
No artificial  sharpening methods are used!

An experimental 3D-study of the Heart nebula, IC 1805


I haven't been able to open up this season yet, since some of my equipment are not yet back from the factory service.

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.

NOTE. A largish image, about 7.5MB, let it load for few seconds.

Image in natural color is taken with the SW 80ED telescope, QHY8 astronomical camera and the Baader UHC-s filter. Exposure time ~5h.

Cygnus mosaic in natural colors, reprocessed


I haven't been able to open up this season yet, since some of my equipment are not yet  back from the factory service. To keep up my processing skills, I reprocessed the great 18-panels mosaic image of Cygnus. Mapped color version was very much OK but I wasn't happy with natural color version.


The 18-panels mosaic of nebulae in constellation Cygnus
Click for a large image. NOTE. A large image, 2300x1500 pixels and ~5MB

Image is in visual spectrum, red light is emitted by an ionized Hydrogen (H-alpha). Blueish hues are from ionized Oxygen (O-III). NOTE. An apparent size of the full Moon is marked at lower right corner as a scale

This 18-panels mosaic is hot with Canon EF 200mm F1.8 camera lens, QHY9 cooled astronomical camera and the Baader narrowband filter set. Total exp. time is around 120h. More information with the original blog post  HERE. Original image is 15.000 pixels wide and over 300MB.

Not a bad resolution for a 200mm camera lens!
