M51 - "Whirlpool Galaxy" in Canes Venatici
   
Telescope: Takahashi Mewlon-250 @f/9
Camera: SBIG ST-9XEI
Mount: Takahashi EM-200 Temma
Guiding: 200mm Takumar lens attached to SBIG STV.
Exposures:

L: 6 @ 5 min. (1X1); R: 1 @ 5 min.(2X2); G: 1 @ 5 min.(2X2); B:1 @ 5 min. and 1 @ 2.5 min.

Processing:

Images were acquired, reduced, and combined with CCDSoft v.5
The Luminance and RGB image were aligned with RegiStar and combined in Photoshop CS. The composite image was slightly cropped and adjusted (Curves). Finally, Gaussian Blur was applied through a channel mask to reduce noise.
Location:

My backyard observatory in southeastern Minnesota. Seeing was mediocre.
Note: This was first light for my new ST-9XEI.
