So much about the first light for this season...

I was hoping to be having an opening picture for the Autumn season 2011 here to show...
Weather broadcast for next six days tells it all.

Season opened... kind of
Last night was finally clear! I took my previous picture at March 15., after that, there was no astronomical darkness to work with, since I live at 65N. My first target was the "Propeller Nebula" in constellation Cygnus.
About six months mandatory pause makes no good ones skills and routines. Last night I forget to plug in a power cord of the filter wheel, stupid me. I thought, that I was shooting H-alpha channel, instead I shot four hours of very weak O-III signal. That's OK, I can use it later for a color image, but due my mistake I have nothing to show here, there is very little to see in ionized Oxygen band . (Mainly stars, noise and some very dim signal from the ionization)
Since I don't have anything to show in this post, please, have a visit in my portfolio, there is some re organization done lately: http://astroanarchy.zenfolio.com/

Moon images from a new point of view

Moon images in this post looks kind of odd...
They are real images of the moon, imaged by me years ago, showing a half Moon with the Earth shine.
(Shadowed side of the Moon get lit by the light reflected from the Earths atmosphere, hence the bluish color)
Actually you can't see the Moon from Earth at this angle!
Images are done by re projecting the moon image to a sphere made by a 3D-software. After that you can select any new viewpoint to a Moon, as long as the point of interest stays on the visible side of the Moon. It's kind of having a private Moon orbiter.
I like this method, since the actual image data stays practically untouched, it just get seen from an other angle.

I developed this technique back in 2005. At the time it gets published by the "Sky & Telescope" magazine.
(J-P Metsävainio, A New Way of Looking at the Moon. Sky & Telescope, Jan 2005, p 142-146.)
I have made several short movies with this technique, here are some links to them:
This movie shows the principle of the technique used:

Couple of image collections with very different instruments, Tokina 300mm camera lens and the Meade LX200 GPS 12" telescope 3000mm
Images taken with a Tokina AT-X 300mm f2.8 camera lens
Images are in HST-palette from the emission of ionized elements, R=Sulfur, G=Hydrogen & B=Oxygen.
Note. Images in this poster are not in same scale.
All images in this collection can be found from my portfolio, with technical details:
Tokina AT-X 300mm camera lens is an excellent astrolens!
Here is a blog post about the lens and the first light for it:

All the images above are shot from my city center observatory, under a heavy light pollution.
The narrowband imaging is must under my conditions. Dark place is better naturally, now I'm able to use every cloudless moment, unlike with an observatory in distant dark location.
A collection of images taken with a Meade LX200 GPS 12" 3000mm f10 telescope, forced to work at ~f5.
My old Meade LX 200 GPS12" telescope, on its original fork mount, is not a perfect instrument for astronomical imaging. I have managed to get it work like a real imaging platform, not an easy task though.
Great help is an active optics unit, SXV-AO, from Starlight express. (UK based company)
