Astrophotography by J-P Metsavainio, a video


Last weekend I participated to a Finnish Star Party at Artjärvi, southern Finland, as a speaker. Thanks to the organizators, everything went very smoothly!

I made a small movie out of the images used in my presentation. At first, there are couple of minutes some quick info, how my photos are taken. Rest of the movie is made out of my photos taken between 2007 and 2016.

Just for a fun, a Kepler launch pareidolia



Kepler is a space observatory launched by NASA to discover Earth-size planets orbiting other stars. The spacecraft, named after the Renaissance astronomer Johannes Kepler was launched on March 7, 2009. I spotted the NASA picture out of the launch and I simply had to do this manipulation to show, how I saw the photo at the first time.

The end, all of my photos from the Winter season 2015-2016

This is a collection of my photos from the past Winter season, Autumn 2015 and Spring 2016. We are now out of astronomical darkness for about six months due to high latitude, 65N. As every time, it's hard to give up imaging the beauty of the deep sky.

The season was very cloudy as usually. We had many months a solid cloud cover this winter and clear nights just now and then. The good side is, that I have been forced to develop new imaging and processing methods to be able to finalise maximum number of photos. The "Tone mapping" method and a new unpublished "VARES" (Variable Resolution imaging method) are very powerful tools for astrophotography. I'll publish the VARES.method in a year or so, after I have tested it well enough.

The last imaging project of the season, PuWe1



This is my last imaging project of the Spring season 2016. We'll lose astronomical darkness day after tomorrow for about six months due to high latitude, 65N.

PuWe1 is a very large and diffused planetary nebula in constellation Lynx. I think this is the first ever three channel narrowband image of it. This planetary nebula is extremely dim, I added single twenty minutes frames at end of the post to demonstrate, how little information there really is.

The data is collected between  16. February and 3. April. Total exposure time is around 23h. To boost the sensitivity of the camera, exposures are mostly shot binned between bin 2x2 and bin 10x10.
Final data is combined so, that high signal noise components, mostly stars, are from bin 1x1 data. Low signal elements are  combined from heavily binned data.

There is a hint of  outer halo visible in this image. It's extremely dim, especially with the focal length used.  I have shot this object with much shorter focal length at Spring 2011. That was the first time I noticed the possible outer structure in this planetary nebula. I like to have this confirmed by some other imager. I will continue this imaging project at Spring season 2017.

INFO

PuWe1, (Purgathofer-Weinberger 1, PNG 158.9 + 17.8, PK 158+17.1) is a large circular Planetary Nebula in the constellation of Lynx. It has an apparent diameter of 20', without an outer halo seen in the image.

The Lower's nebula in visual colors



I have published a photo of the Lower's Nebula in mapped colors about a week ago. Now I'm publishing the same nebula as a visual natural color version.  Narrowband emission from hydrogen, oxygen and sulfur (H-a, O-III and S-II) are combined so, that the result is very close to a visual spectrum. Since the ionized hydrogen emits red light and it usually dominates nebulae, images are more or less red. Blueish hues are from ionized oxygen, O-III. Sulfur, S-II, emits red too and it get mixed to a hydrogen emission visually.

 Image is in natural colors from the light emitted by an ionized elements, sulfur, hydrogen and oxygen.
The mapped color version of Lower's nebula can be seen HERE


INFO

The Sh2-261 (Sharpless 261), also known as the Lower's Nebula, is a faint region of doubly ionized hydrogen. Its apparent dimension is about 50 arcminutes in East-West direction and 30 arcminutes in North-South. So, it has an apparent size about twice the full Moon diameter. Of course the real size of the nebula is much larger! But we have no information about the distance of this hydrogen cloud, so we are not able to determine how large it is.

Supernova remnant Sharpless 224 in auriga



The imaging season up here 65N starts to be over soon, in a week we'll be out of astronomical darkness for about six months. This photo of dim supernova remnant in constellation Auriga is one of the last images for the Spring season 2016.

INFO

Supernova remnant Sharpless 224, Sh2-224, locates in constellation Auriga at distance of about 14700 light years. It has an apparent size about 60 arc minutes, the real size is around 235 light years. This is a very dim target and lots of exposure time is needed to reveal any details out of it. Beside Hydrogen alpha, there are also weak emission from ionized oxygen, O-III, and ionized sulfur, S-II.

A new photo, Sharpless 124, an emission nebula in constellation Cygnus



I shot the lights for this target at January 6. 2016 The data wasn't very good due to weak transparency and a poor seeing at the time. I got this processed just now and the result is much better, than I thought it might be.

There are very few photos and scientific information out of this rarely imaged target. It locates in constellation Cygnus at estimated distance of 8400 light years. Total exposure time for my photo is only seven hours. I will continue with this target at next Autumn, hopefully with better atmospheric conditions.

A new image, the Lower's nebula



We now have had few clear nights after having a solid cloud cover for over two months. Transparency and seeing were poor at most of the time though. I managed to collect some data for two imaging projects. The Lower's Nebula was the first one. This is a dim and rarely imaged emission nebula in constellation Orion. There are not too many photos out of this one and it was difficult to collect information about it. Total exposure time is only 5h, I will continue this project at spring season 2017.

4D video of the Veil Nebula SNR


The weather up here 65N has been cloudy for months. I played with my older images and made couple of  experimental 3D animations out of them. Here is the first one, the Veil Nebula SNR in Cygnus. This is actually a 4D animation since it shows the time too... I made this just for fun, this is not an accurate model of reality but close enough for me.

IC 410 as a cinemascope format photo


I have worked with a cinemascope format movie from my photos for a movie theater presentation. 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.
