Messier 101

 M101-HaLRGB_FinalWeb

Popular Name Pinwheel Galaxy
Catalogue Name M101
Constellation Ursa Major
Distance (Light Years) 21 Million
Photographic Information
Exposure Ha-9x15min L-8x10min RGB-5x5minTotal Integration Time: 5 hours and 5 minutes
Equipment SBIG ST-8300m, Atlas EQ-G, Astro-Tech 111mm refractor,
Processing Deep Sky Stacker, Pixinsight
Imaging Location Golden State Star Party, CA

Notes:

Each red speck within this galaxy is a nebula like any in our Milky Way! These nebulae in the Pinwheel Galaxy emit red light, in the “H-alpha” wavelength. We used an H-alpha filter to get the red nebulae in this galaxy. The dark skies from GSSP combined with the H-alpha data allowed us capture very faint details, such as the sweeping spiral arms.

Leo Triplet

M66-Group

About the M66 Group

Popular Name Leo Triplet
Catalogue Name M65, M66, NGC 3028
Constellation Leo
Distance (Light Years) 36 Million
Photographic Information
Exposure L-2x15min, 8x10min, RGB-6x10min
Equipment SBIG ST-8300m, Atlas EQ-G, Astro-Tech 111mm refractor,
Processing Deep Sky Stacker, Pixinsight
Imaging Location Lake San Antonio, CA

Notes:

We took this image during the wee hours of morning at Lake San Antonio, when Leo was just starting to rise. Processing took a long time, but the result is quite worth the effort. It is interesting to note that the extremely faint tail of NGC 3028 (bottom center) is barely visible in the image.

Notes: This was our first attempt at a mosaic with our CCD, and certain upgrades, such as a new Moonlite stepper focuser have helped us out tremendously. We are very pleased with the mosaic, especially as it necessitated that we learn many new processsing techniques in Pixinisght like Star Alignment and Gradient Merge Mosaic. There is still room for improvement though–maybe we will add narrowband data or another few panes to show all of the nebulosity in that region.
