Now the total exposure time for LRGB is 215 minutes. 961 http://www.kehusmaa-astro.com/2010/07/08/more-data-for-m16 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. 957 http://www.kehusmaa-astro.com/2010/06/27/m17-swan-nebula-with-ng-telescope RGB image of this great looking nebula. Exposures RGB=25:15:20 minutes only! 949 http://www.kehusmaa-astro.com/2010/06/16/m8-lagoon-nebula-with-ng-telescope Me and J-P Metsävainio were able to get some more images for this nebula. Here is updated version with new data added. 945 http://www.kehusmaa-astro.com/2010/06/15/m20-with-ng-telescope-and-extra-data Here is an other example of a beautiful galaxy with great halo and lot of smaller galaxies in background. Equipment: 16" RCOS NG Telescope + Apogee U9000 + Astrodon LRGB filter set Image acquisition: J-P Metsävainio Image processing: Petri Kehusmaa 936 http://www.kehusmaa-astro.com/2010/05/30/m104-with-ng-telescope This is v0.1 of this beautiful nebula. Mora data needs to be acquired. Acquired with NG Telescope (operated by Bert Candusio) Images: J-P Metsävainio / Petri Kehusmaa Processing: Petri Kehusmaa 789 http://www.kehusmaa-astro.com/2010/05/20/m16-with-ng-telescope 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. Image data by J-P Metsävainio and Petri Kehusmaa. Image processing by Petri Kehusmaa 927 http://www.kehusmaa-astro.com/2010/05/20/m20-with-16-rcos-ng-telescope Yesterday I subscribed as a user for Northern Galactic Group's remote control telescope. Today I was able to use 16" RCOS Truss f/9 telescope on Paramount ME mount equipped with Apogee U9000 CCD for more than 4 hours :). The scope and the camera is a VERY POWERFULL combination of ... http://www.kehusmaa-astro.com/2010/05/17/m83-with-ng-groups-16-rcos-truss-f9 Eventually I had to sent my STL-11000M camera to Baader Planetarium (Germany) for repairs. There might be a problem with TE cooler or power source. It's gonna take at least a month to get my camera back. If weather allows, I'm going to pursue few CVs with nice light curves ... http://www.kehusmaa-astro.com/2010/01/12/imaging-camera-out-for-repairs 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. 770 http://www.kehusmaa-astro.com/2009/12/09/m42-revisited
