A zoom in series of the Sharpless 132
Now and then I have published some zoom in series of various objects imaged by me.
The purpose is to show the apparent scale in the sky. Beside that, this series shows nicely the fractal nature of our universe. Series are possible to make, since I have shot many objects with various focal lengths.
Like this one is shot with 200mm, 300mm and ~2000mm focal lengths. Images are from my large mosaic image of the constellation Cepheus.

Note. A circle, size of the Moon, in the images as a scale. (An apparent scale of the Moon is 0,5 degrees, or 30 arc minutes.)

All images are in Mapped colors from the emission of ionized elements,
R=Sulfur, G=Hydrogen and B=Oxygen.

A poster format collection from the Cepheus project
In this collection of my images, the objects shown in a large mosaic of the constellation Cepheus, are collected together. There are indicator lines to show the actual location of object in a large context. As can be seen, I have shot many objects in various focal lengths.
The Cepheus project was my last published image before the major break down of my imaging equipment.

It's over, I cant do my loved astronomical imaging anymore
Sad news, my old Meade LX200 GPS 12" telescope gave up and died.
Two nights ago, when I was imaging, my telescope stopped tracking and gave an error message "Motor Stalled".
It turned to be a fatal problem, the control board of Ra motor was fried. There is no way to fix it myself, the board has several layers and lots of microscopic components. This is a very old scope and it has been under a heavy usage in a very extreme weather conditions. Replacement parts are very hard to find, since this telescope is not manufactured any more. Even if I managed to have needed parts, it'll take the rest of the season to put all up and running again.
This instrument has been way below my level as an astronomical photographer for a years. Lots of desperate looking DIY solutions was used to make this old scope work as a some kind of imaging platform. I really need a new mount and a better optics.
I can't afford to buy any new instruments, it looks like my days are over now. I'm not going to buy any second rate stuff, I'll rather be without, than start fighting against constant malfunctions ones again. I have spent countless hours outside, soldering some bad connectors, in a freezing wind and a bellow -20 centigrade temperatures to fix my scope, not any more.
The only way to solve this is trying to find a sponsor. It won't be easy and it might never happen.
An update, February 02. 2014
After a careful study of damages in my scope, I found out, that not only the Ra motor controller card was toasted. Also the motherboard, Ra motor and its encoder are burned and partly smelted too. This means, that the whole system is beyond repair, least with any reasonable costs.

Three wide field projects, three constellations
Yesterday I published a large mosaic of Cepheus. I have done two other large mosaics from two other Constellations, Auriga and Cygnus. In this blog post I show all three at the same time.
