Snehendu,
Excellent composition, though the moon is overexposed. With your lens, you should be able to get individual craters resolved. But in this image it seems to work. Nice job. Try shooting the moon from a tripod with this lens in a variety of phases. The contrast of a quarter moon makes a wonderful target.

Dan,
The sky is gorgeous, and the image has good contrast and colors. It is easy to overexpose a shot like this, which you did not do. I would have tried to make the right edge of the central tower as vertical as possible. As a result, the chruch tower in the right half wouldn't be leaning quite as much.

Steve,
This image is overexposed. an exposure between 1/2 and 2 seconds would probably been better for this eclipse at your aperture/ASA combination. I am assuming that only some of the white spots are stars and the streaks are some sort of dust. With the overexposure, it is difficult to tell if your focus is on or not. http://www.usefilm.com/showphoto.php?id=134027 is a 5 second exposure at 350mm with a slower film to show what sort of detail is possible. I have a pair of eclipse shots up also, but they are taken through clouds, but the one during totality http://www.usefilm.com/showphoto.php?id=142292 shows the red color of the eclipse, though it is a bit underexposed due to the clouds I was shooting through.

Nicola,
You have good detail in the outer nebula, but the central portion is washed out. Try masking the highlights and using the detail from the shorter exposures to build your composite. You can get more help on the APML (Astrophotography Maillist) which I highly recommend. M42 should have some blue in it, but E200 doesn't capture it well.
Taras
P.S. Most of my photos are taken in the Catskills, though I have made a few attempts in the city. My web site has an M42 photo taken from my roof in NYC http://homepage.mac.com/tarashnat/astrophoto/0004-26.html in a one minute exposure.

And this is what you could pick up on the belt with an appropriate film. Mind you, both of these exposures were 30 minutes long, and manually guided.

Nicola,
Try this shot next time with a film that has better red response. Many of Orion's treasures glow in the Hydrogen alpha wavelength (656nm if I'm not mistaken). Kodak Ektachrome E200 and Fuji Provia 400 are two films that seem to be the best for this sort of work. They happen to be slide films, all the good negative films have been discontinued. The Orion Nebula should appear pinkish, and the Flame and Horsehead nebulae did not appear; they would be to the left of the left most star of the belt. Also, if you are shooting from a dark site, try a longer exposure if you are careful with polar aligning your mount. The attached photo shows what color you can get with a decent film. This was the old Supra 400 and a 200mm lens on a Minolta body. The new formulation has lost the red response.

The centering has everything to do with cropping. I did a quick and dirty crop on the partial phase. The original on that was better centered. Image http://www.usefilm.com/showphoto.php?id=134027 shows what this lens is capable of. My original plan was to use the 8" telescope to photograph the moon during the eclipse and to use a 50mm lens on the Hassy to compose a time sequence multiple exposure. Well, as you said, nature wasn't too cooperative.

I used Logitech's QuickCam software for Mac OS 9. No payloads on Ariane rockets nor DOS/Windows? software was used in the creation of this image.
Check out the QuickCam and Unconventional Imaging Astronomy Group at http://www.qcuiag.co.uk/ for info on how to use a lowly web cam for astronomy.

It looks like the Canon and Minolta 135mm f/2.8 lenses are both of high quality. See http://www.usefilm.com/showphoto.php?id=106935 for my take on the North America Nebula's place in the Milky Way. Try a longer exposure on this target if you get the opportunity or an autoguider.
Taras
P.S. This image belongs in the landscape category (See http://www.usefilm.com/categories.php ).

The biggest problem was the clouds I was shooting through. Just a look at the shape of the "shadow" shows more than just the earth's umbra. Those are clouds. If it wasn't for the 98-101% overcast skies, I would have used the LX200. The uncropped original isn't as off-center as you may think... see attached.

This is the best moon shot that I have seen with such a wide lens. And capturing the earthshine so nicely. And as a bonus you have a few stars as well. I have a similar shot, but with a much longer lens: http://www.usefilm.com/showphoto.php?id=134027

Nice work. The exposure is long enough to get great colors, yet short enough so that the full moon does not look like a sausage. Well done.

Geoff,
Nice individual exposures, but this image would be stronger if you paid attention to the positioning of the elements in this composition. If the moon was not overlapping the tower, this would be an excellent example of a double exposure adding the moon.

I assume that you just cropped the image without scaling it. This lens sure has great resolution. The focus is bang on, does this lens have a stop at infinity?

Bill,
The dot in the lower right is an airplane strobe. That is in the line of an airplane trail. The satellite is a faint diagonal line near the center of the photo. There is an orange streak in Camelopardalis on the left edge, which I have no idea what it is--my first "UFO"?

Kelly, the city lights have no effect on lunar observation/photography. The moon, even in eclipse, is too bright to be effected much by city lights.
Bill, great shot, considering your equipment. I was planning on shooting with my telescope (1280mm focal length), but for the most part got clouded out.

Nice colors on the moon. I could not detect any color visually from NYC because of all the cloud cover. I did get a peek during ingress and and one during totality, but I will find out later if either of those two attempts yeilded any useful results.
