Back in 1993, this was my first target with a SBIG ST-4 guider. I attached the guide camera to an off-axis guiding holder attached to my 125mm Takakashi refracting scope. I didn't know what to expect since I had never done any off axis guiding before nor had I ever used an auto guider. Anyway...I gave it a go to see what would happen. I do remember that I used some sort of Ronchi eyepiece to focus with. I used a Nikon High Eyepoint SLR camera and Fuji HG400 film. The image was taken at prime focus and for a duration of 35 minutes. Of course, I had to wait a week until the film lab was finsihed with the processing. I was pleased to see that the stars were pretty sharp and I then had an 8x10 made. I sent this image to Astronomy magazine and it appeared on the inside cover of their February 1995 issue article entitled "Seven Easy Star Clusters". A lot has changed in that 27 years when I captured this image with what now would be described as archaic methods but I still have fond memories of that evening. As my little ST-4 was buzzing and peeping as it tracked the guide star, I happened to see 36 glowing red eyes looking at me. It turned out the peeping attracted a large contigent of coyotes. They were about 10 yards away and I shouted and they scattered...lol. I guess they were just curious but they were a bit too close for comfort. My second object of that evening in 1993 was M31 and the first image went well. Then I decided to image one more time and that's when my little ST-4 went bonkers! Turned out that a satellite happened to pass through my guide star and poor little Homer (my ST-4) tried to follow the satellite :o). The mount drive really hummed and I ended up with this beautifully smeared image of M31. So...you just never know what's going to happen on your photographing expeditions :o).
