More high resolution, cinemascope format, panoramas from my astro photos



I have worked with a cinemascope format movie for a movie theatre presentation from my photos. This is an extra wide ~21:9 format used in theaters. The actual film is not ready yet but I have some of my images converted to this ultra wide format. I think they will look great at a large movie screen! I'll publish some of individual panoramic format photos here, images are downscaled for the web.

NGC 1499, the California Nebula, project continues



It has been very cloudy up here for about several months now. At January 4. I was able to shoot some lights for the NGC 1499, the California Nebula. We had few hours of clear sky at February 1. I shot three hours of H-alpha light next to previous image to build a two frame mosaic. Colors are partly from an older wide field photo of the california Nebula.

Image area spans about two degrees of sky horizontally. The photo is in mapped colors from the light emitted by an ionized elements, red=sulfur, green=hydrogen and blue=oxygen.

Please, click for a large image

A wide field image of the NGC 1499 from January 2012 was shot with a Tokina AT-X 200mm f2.8 lens, QHY9 astrocamera and Baader narrowband filter set. The white circle at lower right corner shows an apparent size of the full Moon at the same scale. (Moon has an apparent diameter of 0.5 degrees = 30 arc minutes.) This is a large target with a lowish surface brightness, total exposure time is around 30h.

INFO

The California Nebula is an emission area located in constellation Perseus. It appears to resemble outlines of State of California on long exposure photographs, like this one. It has a very low surface brightness and it's very difficult to observe visually. Distance from my hometown Oulu, Finland, is about 1000 light years.
this image spans around five degrees horizontally. The Wikipedia article states, that the angular size is about 2,5 degrees (Five full Moons side by side) but as can be seen in this image, the actual size, with a dim outer parts, is much large.

Filaments of Cygnus in visual spectrum



This is a visual color version of my first picture for the year 2016. I published the Mapped Color version at January 7. This is a two frame mosaic project of the central Cygnus. It was shot at freezing temperature of - 27 degrees centigrade (-17 fahrenheit). Exposures are from three nights between 3. - 6. january 2016. Total exposure time 15h.

Natural color composition from the emission of ionized elements, R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission. This composition is very close to a visual spectrum.

Astro Anarchy gets published



My astrophotos are selected as a public content to a pedestrian zone in my hometown Oulu, Finland.
There is a very large display unit at the main square, 5.12 x 3.2 meters (over 16 x 10 feet).

Six different sets of my astronomical photographs and animations are running there as a slideshow during the January 2016. The show will run at every 15-25 minutes and last about three minutes at the time.

Abell 85 (CTB1), a dim Galactic Supernova Remnant in Cassiopeia, project finalized



I started this imaging project at January 2015. This January 2016 I was able to shoot more exposures for this dim target to finalized my imaging project. It's always a pleasure to have the image ready after a long period of time. As usually, I compared my exposures from different years to see has anything happened up there during the year. Usually there are no difference other than seeing conditions but this time I spotted a suspected variable star in the image field. (NSV 26187) There is an animated image in this post to show the difference between the years 2015 and 2016.

INFO

Abell 85 is a very faint supernova remnant in constellation Cassiopeia. It's difficult to image with any details due to extremely low surface brightness. Abell 85 has a largish diameter, about half a degree, it has a same apparent diameter as a full Moon. The physical diameter is about 98 light years across. This SNR locates about 9800 light years from the Earth. CTB1 was originally thought to be a planetary nebula and it was included the Abell catalog of planetary nebulae under a name Abell 85. It was confirmed to be a supernova remnant by Willis & Dickel at 1971.

NGC 1499, the California Nebula



At the night of January 4. I was shooting exposures for the Filaments of Cygnus image. After few hours the constellation Cygnus was getting too low in the horizon and I had to select a new target for rest of the night, the NGC 1499.
