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.
Note:

IC410 is at the top; IC405 (the Flaming Star Nebula) is at the bottom. The small nebula at the extreme top and right is IC417. The open cluster to the extreme right and top is NGC1907. North is toward the right.
