Latest image from Australia is M17 alias Swan Nebula. This is a narrowband image taken with Ha, OIII and SII filters. Exopsures are Ha:OIII:SII=120:20:40. Ha was also used as luminance layer in Photoshop.

Today I was able to continue using this magical telescope in Australia. Scope was operated by Bert Candusio locally and I used the control computer with VNC.

I’m going through my old images and reprocessing them with new tricks I’ve learned after watching Adam Block’s DVD. Here is M42 from last year.

This nebula is very hard to image at these latitudes where it rise only about 15 degrees above horizon and summer night skies are still very pale. Anyway, I gave it a try and somehow succeeded to have even colors. The blue channel images were almost unusable but I managed to get something out of them. Imaged with 8″ SCT and STL-11000. Total exposure 160 minutes.

I combined my latest image with earlier M42 image and was able to get total of 3.5 hours of exposure. This is the result and will be my final for season 2007-2008. Next time I will return to this on November.

Rainy days might be rewarding after all. I had some time to browse through my image directories and found 1 minute sub exposures taken on January. I put them together (HaRGB) and here is the result. Total exposure time is 50 minutes. More details in my image gallery (click image).
