This new photos shows the LBN 251 and companions in Cygnus

My latest photo show a busy area in Cygnus, there are not too many photos out of this area alone.

My large mosaic image of cygnus shows this object group as pow tie shaped formation.

A very rare photo, Cygnus Shell, supernova remnant G82.2 + 5.3 W63 in visual spectrum

I have now finalized my imaging project with this not so well known, supernova remnant, W63, in Western part of the constellation Cygnus.

This time I made a version in visual colors from narrowband channels.

Red light from an ionized hydrogen, H-alpha, is dominating the scene. The actual supernova remnant glows in blueish light emitted by an ionized oxygen, O-III. The mapped color version can be seen in my previous blog post.

The final photo is a twelve panel mosaic with a total exposure time of over 100h. Image is shot with a Celestron Edge 1100 (with a 0.7 focal reducer), Apogee Alta U16 and AstroDon narrowband filters (5nm H-alpha 3nm S-II and 3nm O-III)

Individual panels are shot between years 2015 and 2018. O-III and some missed data are shot at this ongoing Autumn season.

Image is in Natural color palette from the emission of ionized elements, R=Hydrogen + Sulphur, G=Oxygen and B=Oxygen + 10% Hydrogen to compensate the missing H-beta emission.

INFO

W63 (G82.2+5,3) is a large supernova remnant that can be observed in the north region of Cygnus at distance of about 5200 light years.

It spans around 100 arcminutes and its filaments are expanding at speed ranging from 35 to 70 km/s. In 2004 the existence in this supernova remnant of an X-ray pulsar with 36 second period was reported.

A very rare photo, Cygnus Shell, supernova remnant G82.2 + 5.3 W63

I have planned to shoot this very difficult target for many years. At this Autumn season I had a possibility to finalized my imaging project with this, not so well known, supernova remnant W63 in Western part of the constellation Cygnus.

The final photo is a twelve panel mosaic with a total exposure time of over 100h. Image is shot with a Celestron Edge 1100 (with a 0.7 focal reducer), Apogee Alta U16 and AstroDon narrowband filters (5nm H-alpha 3nm S-II and 3nm O-III)
Individual panels are shot between years 2015 and 2018. O-III and some missed data are shot at this ongoing Autumn season.

Image is in mapped colours, from the emission of ionized elements, R=Sulphur, G=Hydrogen and B=Oxygen. This mosaic image of twelve individual panels covers about four degrees of sky vertically.
