IC443, a start of the new project
False color Hydrogen alpha

IC443 is a supernova remnant in Gemini.
Last night I installed a Tokina 300mm AT f2.8 lens front of the QHY9 astro camera.
This combination gives me resolution of 3,5 "/pixel, witch mean practically seeing limited
details. The fiels of view is about 207' x 157'.
-
At the time I was able to shot this target it was low in the sky, about
30 degrees, that and very bad transparency and seeing cut down the sharpness a lot.
-
I will shot more Ha-light when weather allows and I'm going to
add O-III and S-II data as well to create a narrowband composition.

Imaging details:
Optics, Tokina 300mm AT f2.8 @ 2.8
Camera, QHY9 astro camera
Guiding, QHY5 and PHD-Guiding on LX200 GPS 12"
Exposures, 8x600s +darks, bias and flats
Filter, Baader 7nm H-alpha

Rosette Nebula as a Stereo pair.
I turned this image of Rosette Nebula to a Stereo pair format by
adding some volume.
The result is more or less an educational guess about real 3D appearance of this formation.

Two versions, first for Parallel Vision , and the second for Cross Vision method.

Sh2-240, more lights
This is a second version of Sh-240 this year.
I added more H-a light. Now image is smooth and signal / noise is
improved. I might shoot more lights for this later in this spring.
-
Two versions, first in Hubble palette and secon in "natural" color narrowband composoite.
-
Exposures so far are:
H-alpha, 12x600s + 24x300s(binned 2x2) + 12x600s = 6h
S-II, 5x600s (binned 2x2)
O-III, 14x300s (binned 3x3)
-
Optics: Canon 200mm EF f1.8 @ f1.8 Camera: QHY9 @ -50 C Guiding: Lx200 GPS 12" + LQHY5 and PHD-Guiding - The information in O-III channel is extremely weak. I used a special technique of mine to dig it out for color information. This image serie shows how weak the O-III realy is.
