The Rose

Again three weeks of cloudy skies.And finally the chance to do some imaging again. Seeing was not very good (FWHM ~7''), but you've to take what you get.As winter is coming, also new nebulas and constellations are now visible. One of these is the wonderful Rosette Nebula. The resulting image consist of about 3 hours of exposure time. I still have problems with guiding, I am not able to nail down (due to only being able to do stuff every three weeks).Also dew is becoming a problem in these cold autumn and winter nights.The images still lack the sharpness quality I would like to have, but with t…

Center of the Heart

Another one of the Heart Nebula. This time directed at the glowing center. The full Nebula is actually a little too big to fit onto the small 10mm sensor of the Atik Camera. Maybe I'll add some additional images in the future and try to build a mosaic.

Hunting Orion

Winter is coming and this also means that Orion the Hunter is again showing up on in the sky.After three weeks of mostly clouds skies I got my APO Refractor out to do some imaging. In the meantime I also learned that ma problems with guiding and blurry stars also seem to come from very poor seeing over Innsbruck.The following images have a sharpness value (FWHM) of 7 arcseconds for stars. Astrophotographers in better regions of the world don't bother shooting if this value goes over 4. Looking back at old images I found out that the sharpest I got from my Garden location was 3 arcseconds.But a…

The Heart must Follow

I'm really fighting with field rotation.If your mount is not aligned perfectly to the polar star, even with good guiding, this puts strong constraints on your exposure times. Even off axis guiding does not solve this problem. If you miss aligned just 1', the guiding star is 2 degrees away from your image and you're 60 degrees above the horizon, field rotation will accumulate on a 30 min exposure to about 5 pixel on my Atik 490ex.As I build and tear down my setup for every session, there is a limit of time I'm willing to spend for alignment. All Star Polar Alignment on my mount gives me about t…

First Light Atik 490ex

After spending an amount of money one should not spend for a past time, getting the camera last week and then waiting 7 days for clear skies - finally.Below is IC1318, the nebula in Cygnus. I chose this target because it was relatively high in the sky (advantage in a light polluted city), but not too close to the zenith (which makes guiding a pain).The image is the result of 5x5 min of H-alpha, H-Beta, O-III and SII. Because of the short exposure time (I was still playing around), only H-alpha and SII really had significant impact.I also learned some lessons. Make sure to remove all dust from…

Hercules, the Sun and the Moon

Just some quick shots during a clear night of the Moon and M13. M13 was done with the APO, the Moon and the Sun are 2 image composites done with the EdgeHD. I'm still amazed of about the quality of the APO/Flattener combo.

Playing around with America

I decided to give the North American Nebula a try with my new APO.First setup was my unmodified EOS M3 with the 480 mm APO and the flattener from my light polluted garden. The nebula was close to the zenith which makes the sky a little bit darker. Total integration time was about hour.The signal was really weak. Below is the result after pulling all my post processing skills.

Next night I tried it with my Baader H-alpha filter. As my current setup for the APO does not work with flattener AND filter, I had to make the pictures wit…

First Light with new APO Refractor

After my last experiment with my old 100 Euro ST80 400mm Refractor I got myself a new toy: A 480mm APO Refractor with extra Flattener.Below is the first image I did. Because of incoming clouds I just had only time for 2 quick 45 sec snaps of M15. But both the colors and shapes of the stars are so much better with this refractor.Looking forward to some truly dark nights on Hinterhorn Alm for some long exposure rich fields.
