Concert, thousand year old vocal music with astronomical photos
During last weekend I have had two concerts with two vocal ensemble Cappella pro Vocale from Oulu and Punctum from Rovaniemi. Thousand year old vocal music with my astronomical photos turned to be a timeless combination. This was my second production with Cappella pro Vocale, we did a similar Christmas concert in Oulu last year.
My imageshow was matched with music and it was projected on the walls and ceiling with four power projectors. Concert took place in two places, first one was in Oulu, Finland at the Church of St Thomas, the second one took place in Rovaniemi in Northern Finland at the Chapel of Korkalovaara.
Many thanks to Cappella pro Vocale, Punctum and all of the visitors!

IC 1936, a closeup
I have spent most nights at this Autumn season by shooting dim targets around Cygnus.
At night of 2. November I shot few frames from a brighter target, IC 1396, in Cepheus. Just one hour of H-alpha light and one 20 min frame for O-III and S-II before clouds rolled in. Just got the data processed and the photo turned to be kind of nice, so I'm publishing it here. This is a second photo out of IC 1396 at this Autumn. The first one from the Elephant's Trunk Nebula can be seen HERE.

Filaments of Cygnus, a new processing for natural colors
As usually, I reprocessed the two frame mosaic of Cygnus filaments. The color balance and stars are better now and more details are visible. This area in Western Cygnus is rarely imaged since it has a low surface brightness and more attractive targets are nearby.

More filaments of Cygnus and couple of planetary nebulae
I just got this photo processed. It's showing an area near the Propeller Nebula, I noticed this dim planetary nebula candidate, PN PM 1-320, back in 2011 while I was shooting the Propeller Nebula with my 300mm Tokina lens. At the same image field there is another planetary nebula too, PK 84+9.1

Filaments of Cygnus
There are lots of dim gas filaments at west side of the Cygnus nebula complex. I have spent this Autumn season by shooting them. Due to close proximity of brighter and more eye catching nebulae in Cygnus, this area is not very commonly imaged.

Sharpless 114, Sh2-114, the Flying Dragon Nebula
I have spent this Autumn season by shooting rarely imaged dimmer targets around Cygnus. So far I have stayed at Western parts of Cygnus nebula complex. This time I picked a target form the Eastern side, Sh2-114, the Flying Dragon Nebula. There are very few images out of this dim nebula.
This is a preliminary processing, I will shoot more exposures for this, whenever weather up here allows me to do so.

INFO
Sh2-114 is a complex and unusual HII emission nebula. Its complex, wispy structure is likely the result of winds from hot, massive stars interacting with the magnetic fields in the interstellar medium. But very little is known about it. (Source, https://www.noao.edu/image_gallery/html/im1112.html)
There is a planetary nebula at the same field of view, Lan 384 (Kn 26)
Using existing digital sky surveys, Jacoby et al. (2010) presented Kn 26, a bipolar PN candidate known for a long time as the emission line source Lan 384. Here we present high spatial-resolution optical and near-IR narrow-band images of this nebula, high-dispersion long-slit echelle spectra, and low-resolution spectroscopy. The new data confirm the PN nature of Kn 26 and reveal features typical of bipolar PNe: butterfly morphology, H2 emission, and nitrogen enrichment. A detailed analysis of the morphology and kinematics, however, suggests the possible presence of two pairs of bipolar lobes that would make Kn 26 a new member of the class of quadrupolar PN.

Filaments of the Western Cygnus
I have spent some clear nights by shooting dim gas structures in Western part of the nebula rich constellation Cygnus. This area of Cygnus is not commonly imaged due to low surface brightness and close proximity of more eye catching nebulae. My previous project of Western Cygnus can be seen in this blog post.
This time I shot a formation around the magnitude 3,96 star, OMI02 Cygni. It can be seen as a most brightest star at middle right. This is a two frame mosaic image.
