Last night I took Bonnie out for a walk and noticed a nice Red Orange Crescent Moon. It was close to the horizon so I had to work really fast to capture it. As it was, I didnít have time to hook up the TC-80N3 remote and use mirror up. I had to take what I could get at 1 second and f7.5 (wide open) with an Orion 80ED scope. The scope was mounted on a Televue Gibralter Alt Az mount and wood tripod.
The redish/orange color is as I saw it. The image is unmanipulated. The color was caused by smoke at high altitude from the fires in California. I have seen and confirmed this phenomenon before. Iím in Louisiana so we are a long way from California..
These photo are a pretty good illustration of the HOT PIXEL problem of these digital cameras. My camera is almost 7 months old and I started noticing a couple of hot pixels at exposures that should not present this type of problem. When I first got the camera I shot dark frames at 1 to 300 seconds and 100 to 1600 ISO. While I had the normal amount of noise with longer times and higher ISOs I did not have any hot pixels even remotely like the ones that these photo illustrate.
I will have to send my camera in before the warrantee runs out to have the CMOS remapped.
This is just a heads up for who ever might be interested.
The first image shows the moon just starting to descend into the trees. The hot pixel is in the left edge of the shadowed moons disk, almost in the exact center of the frame. It is the little green spec.
The next image is a 100% crop and the hot pixel is more obvious.
The third image is a 1600% crop.
No sharpening, noise reduction or any image manipulation has been applied to the first three hot pixel images.
This last image has been sharpened, the hot pixel has been removed and the levels have been adjusted. The image has been cropped 35% into an 8x10 format. No color or other adjustment of the photo has been made.
