Central Auriga Mosaic

 
 
This region of Auriga contains many fascinating objects. IC405 (the Flaming Star Nebula) is at the top; IC410 (containing the Tadpoles) is at the bottom. The small nebula at the bottom and left is IC417. North is toward the right.
   
Lens/Scope: SMC Takumar 300mm f/4 (for Ha)
Takahashi FS-102 @ f/8 (for film)
Cameras:

ST-2000XM w/CFW-8 (Schuler Ha filter)
Mamiya 645

Film: Fuji Provia 400F
Mount: EM-200 Temma
Guider: STV w/135mm lens
Exposures:
Ha: 5x10 min. (unbinned) for each of the four frames used in the mosaic.
Film: 2 @ 60 min. and 1 @ 45 min. Images were aligned and median combined in RegiStar.
Processing: CCD images were captured using CCDSoft v.5. They were reduced, histogram adjusted, aligned and median combined with AIP4WIN and CCDSoft. The four separate images were assembled into a mosaic in Photoshop 7 and adjusted (cropping, Curves).
The film composite was aligned with the Ha mosaic in RegiStar and manually combined in Photoshop 7. I blurred the Ha/Film image and increased its color saturation before adding it again to the Ha mosaic (blending at 100% Luminosity). Finally, Grain Surgery was used to reduce noise.
Location: My backyard in SE Minnesota.
