First flight of the Wright Flyer on Netersel model airfield

These are the pictures of the first real flight of the Wrightflyer at the model-airfield near Netersel where we also do our observing with the telescopes. It is a beautiful airplane, everything is constructed by hand, except for the engine. This has been a project that took years, the (already very experienced) pilot had to train himself in flying this airplane doing small jumps. It took him about 1 year to master it, including many finetuning/modifications on this airplane. But he succeeded!

M27 with the Artemis 4021 CCD and Hutech LPS-P2 filter

 Last fridaynight I photographed M27 (The Dumbell Nebula). It is a planetary nebula, when a star the size of our Sun reaches the end of its life it blows away its outer shell, this is visible as a so called planetary nebula (because people first thought it was a planet instead of a star).
This picture was shot using my Artemis 4021 CCD, cooled to -15 degrees centigrade on my 200mmF5 Newtonian, riding a NEQ6 pro mount.
It is a combination of 7x 1200s

Here is a enlarged version of this beautiful nebula.

NGC6914 with LPS-P2 filter

This is NGC6914 again, but now 2x1200s with the Hutech LPS-P2 filter.

NGC6914 with UHC-S filter

After using adapters to move the coma corrector to 55mm from the CCD I tried NGC6914 again, this time with Baader UHC-S filter. The coma is substantially reducted, with finetuning I can even achieve a little bit more I think. I also experimented with a Neumann flatfield EL panel for shooting flatfield calibration frames. This also improved the picture a lot. After that I experimented stacking the pictures in Nebulosity. There it showed that there was a lot of moisture on the pictures, so I could only use the first two of 1200s I shot. I made a new badpixelmap in Nebulosity and stacked the first two of the session, this is the result. The UHC-S filter blocks a lot of light compared to the Lumicon Halpha pass. I think I will use the Halpha pass again next time.
