Monochromatic way of imaging

Narrowband imaging is a nice way to fight light pollution. Event under suburban sky it is possible to achieve decent outcome. Here are two narrowband attempts - only hydrogen alpha channel so far. 
IC471 and NGC1931 nebulaes called also Spider and Fly:

Spider and Fly nebulaes

And rarely pictured area around Sh2-104 hydrogen fuzz-ball in Cygnus:

Medusa in stars

Abell 21 - that's how Medusa Nebula is named in the planetary nebulaes catalog created by George O. Abell. It is quite old nebula, already pretty diffused in the interstellar medium. 
The piture below has been shot at the end of the year 2015. It is total a little bit over 10 hours of exposures, most of them made in the hydrogen alpha filter. Plus 3h of oxygen signal, and 2 hours of total RGB. Made with TS 130/910 0.79x refractor and Atik383 camera on EQ6 mount.

Abell 21 Medusa Nebula and NGC2395 open star cluster

In the upper right part of the frame there is loose open cluster - NGC2395. And when you enlarge the picture there is small blueish star in the nebula center. That is WD0017+283 white dwarf, that originated this nebula. 
Here there is only hydrogen frames stacked, inverted and stretched. You can see the faint outer part of Abell 21. Kind of "tail" that nebula left behind traveling through interstellar medium.

Clear skies!

Open cluster trio (astrosclerosis)

I was a little bit busy during the night of December, 30th and I have been looking for quick 2-3h frame. The M38 cluster in Auriga and its surroundigs has been choosen. Then, few days later during image processing I realized that I pictured exactly the same area one year ago http://astrojolo.blogspot.com/2014/11/young-and-old-clusters-and-carbon-star.html . Bummer. Only difference is I pictured it now with different telescope - TS130/910. One year ago it was 6" newton.
So here it is RGB 3x10x5 minutes:

M38 open cluster and surroundings

There is alco NGC1907 cluster at the bottom, and Czernik 21 open cluster at upper right, at the and of faint red nebulosity (that is Sharpless 230).

Clear skies!

C/2013 in Pegasus

Comet C/2013 PanSTARRS is currently travelling across Pegasus constellation. It is approaching to the Sun to reach perihelion in April, 2016, and it is currently moving away from Earth (but it will change after comet pass perihelion - we meet again :) 

C/2013 X1 PanSTARRS orbit (comet is moving CCW, Earth is moving CW)

Two days ago I pictured this comet. Transparency was poor, but the comet is quite bright, so it appeared clearly.
Picture below is RGB stack 3x10x3 minutes, so 90 minutes total exposure. Current setup: TS130/910 0.79x, Atik383, EQ6.
