Here's a couple more of my favorites.
Another example of simple astrophotography .... the moon through fog, making a halo. Although ALL haloes are actually raindow-colored, we usually don't see this with our eye. The colors are just too subtle to activate our color recepters. A 1-second exposure with a digital camera works just fine however. (My scope is set up now with a front-mounted piggyback, to keep the dew-shield from hogging the bottom of the image. The camera is so heavy that I had to use it on back until I was able to rig up a proper counterweight system, to keep from straining the drive motors):
The next one is the only shot here which actually required a telescope. It's an SBIG CCD camera, at Prime Focus through the 12" scope. I thought it was neat because it shows the landing site of Surveyor7, right at the base of the crater Tycho. That's the one you can see with the unaided eye, which has ejecta rays stretching all the way across te Moon.
A close-up like this will pracically eliminate the rays, although you can see a trace of them on the right side of the image. But these type shots reveal the inner structures of the craters.
One curiousity here .... if you look right above the 1st "r" in "Surveyor", you can see what appears to be a scratch, or a canyon. That's actually just a mistake I made. This CCD magnifies so much that the FOV wasn't big enough for what I wanted here. So I took 1 exposure, then slewed the scope a bit to the North & immediately took another identical exposure. I then stitched the 2 together.
This is almost impossible to do with 100% accuracy for 2 reasons, one of them preventable. The 1st is that there is so much fine detail on the Moon, as compared with most other celestial objects, that any amount of turbulence in the atmosphere will show up on the image also. Thus, no 2 images will ever be identical. That's NOT preventable.
The preventable one is that a telescope has several different drive speeds to it, depending upon what you are tracking. "Sidereal" is the default speed, which is one revolution every 24 hours. That is to track non-moving stars, which are only moving because of the rotaton of the Earth.
However, the Sun, Moon, & transient objects such as asteroids move at different speeds. Being as this was only about a 1/100th second exposure, I thought I could get away with NOT switching the scope over to "Lunar". But at this high magnification, it still caught the difference. The Moon is so fast (27 days to cover 1.5 million miles), even that slight 1/4 degree change in my scope's altitude produces an image a bit more tilted one way or another. So it's VERY hard to line 2 images up perfectly.
Looking below the word "Surveyor", you can see where the image is blurred a little from lower-right to upper-left. I was able to process this blur out of most of the rest of the image by warping it. But here, near where the 2 images are stitched, I just couldn't manage to do it:
