Autum 2007 H-alpha images

LX200 GPS 12" f6.3 + SXV-AO (Active Optics system)

H-a 4h Elephants trunk nebula in IC 1396

LX200 GPS 12" f6.3 + SXV-AO (Active Optics system) The core of IC 1805 4h of H-a

LX200 GPS 12" f6.3 + SXV-AO (Active Optics system) Bubble nebula 4h of H-a

ED80, guided with LX200 and QHY5 camera+PHD-guiding 2h of H-a

SXV-AO, Active Optics sytem first light

Comparison image of AO and no AO system.

On the left side Bubble nebula 4h HaRGB image, guided with SXV-AO.

On the right side, older, 2h UHC RGB image from spring 2007.

Right side image is guided with traditional sytem, ED80+QHY5 camera and PHD-guiding.

LX200 GPS 12", QHY8 cooled 6mb color cam.

4h H-a + 2h RGB with UHC-filter

STEREO 3D tests, just fof fun!

STEREO image test for "parallel viewing"

STEREO image test for "cross vision"

M31 is beautiful and very problematic target. Large angular size, low surfage brightness and large dynamic range combined to heavily light polluted location, is not a good combination. Anyhow, here is the result this time. I really need a darker location. SW80ED and QHY8 guiding LX200+QHY5+PHD-guiding 4h total exposure time.

M33 is adifficult target from light polluted evnironment.I use four hours of exposures for this. Noise porblem and very low S/N are coused by LP. SW80ED QHY8, guided with LX200+QHY5+PHD-guiding

I had some extra time, so i went trough my archives. Here it is famous 17P/Holmes. At the time it was easy to spot with naked eye. Two hours of exposures with QHY8 and SW80ED.

M56 & M66

M51

M81

M101

NGC 4565

NGC 5907 (Pizza?)

M82

M106

Sun Flower Galaxy

M13

My very first DS image ever.

I was very proud, that I was able to see spiral arms

in my picture! Image is taken in Alt/Az mode acd there was

only 12x30s subs, no guiding.

NGC3718, thanks for solving it Philipp

Moon Images from 2004-2006

I have had few images in famous LPOD http://www.lpod.org/

I have had an article about Moon 3D transformation in Sky & Telescope. (J-P Metsavainio, A New Way of Looking at the Moon. Sky & Telescope, Jan 2005, p 142-146.)

Here is a few sample images from the past.
