The Orion Nebula with the Televue TV-85 Refractor.
This was 84 sub-images of 3 min each at ISO 800 combined with 5 subs of 15 minutes each shot at ISO 400. All images done with a Televue TV-85 with a 0.8x focal reducer for F/5.6 speed, a Canon T3 modified DSLR camera and a IDAS-LPR filter.
I took this with my Televue TV-85 refractor and combined 2 nights worth of data. The exposures ran like this: 46×180″ ISO1600, 11×900″ ISO400 and 57×360″ ISO800. Gamma Cassiopeia is the really bright star in the center and overwhelms the sensor, so I had to suppress it quite a bit in processing.
This is a composite image of the Belt of Orion area combining images shot with a Canon 200 mm F/2.8 lens at F/3.5 and at F/2.8, plus the Orion Nebula area and Horsehead area each imaged separately with a TV-85. RegiStar was used to align the separate images and PSCS2 was used to stack and blend the images together and crop them to form the final version seen here.

One of my better images of this rich Milky Way area containing the Trifid and Lagoon Nebulae. Shooting in the middle of summer is always tough, but I got a break when I took these some time in July of 2007.
Back when the southern sky was still dark enough to shoot long exposures, I managed to do 3 minute subs at F/2.8 and ISO 400 speeds. Taken sometime in July of 2007.
