Wow.... that's a nice picture. I wish I had a scope & mount half that good.

There was some bad blue CA I had to fix up (note the grey halo at
the top right). Now the 10D is going to make me buy a better scope
and mount, I guess it really will never end....

Wow. That's a real great photo of the moon.

I tried taking one of the moon (just for the heck of it) and all I got was a white blown-out spot which was the size of dime.

What was your shutter speed? A near full moon is bright enough you'll have to use a fairly fast shutter speed.

You need to use manual mode for the moon if you are using anything less than, let's say a 300mm lens. Because even an exposure compensation of -2 might still over expose the moon. At around 300mm or longer the moon is big enough that the camera can get a reading on it and other modes might work.

Here's one taken with a 75-300 USM lens. The lens isn't the sharpest so I stopped down and applyed alot of unsharp mask:

I find the moon to be a fascinating subject. Here is one I took on August 11th at midnight. I took a shot of Mars as well but it's only a few pixels in size. Your scope would have been very helpful! :)))

I tried it last night as well - just a blown out white dot.

Faster shutter speed? 1/50th is what I saw in one of those.

Any other suggestions? Exposure Compensation? I have a 10d with a 70-200 2.8 Sig.

Thanks!

Great shots from everyone.

... You've given me a good chuckle. I was out the other night taking moon shots with my 75-300mm USM IS lens. I was mostly ambivalent with the results, but your shot now confirms this: They all sucked. :-D

Excellent shot. I have 105mm reflector, and I need to get off my butt and try this with the right equipment and technique.

Thanks for sharing.

Greg, think of the moon as a sunlit landscape. The same camera settings apply to the moon. I use F:8 at 1/100 and sometimes bracket by plus/minus 1 stop. I use manual setting for this since the AE sensor will be fooled by the black of the sky. At 200mm you will get a pretty small, but usable image. Ideally you should have a focal lenght of 1600mm+ to fill the frame.

Have fun

What a nice shot Marty! Here is a shot with a 10D at 400mm and cropped heavily...no sharpening or any postprocessing, and though I like it, there is no comparison to your image.

Hi Marty,

To get good moon shots really doesn't take too much more that what you have - if any. I suspect part of the issues with CA, if not all, came from the Barlow. Eyepieces and barlows are almost always responsible for CA since the mirror can't produce it.

The slight softness probably comes from not locking up the mirror and using a remote release - the moon's a "long" way off and even slight mis-focus or camera shake can introduce significant blur. Here's a D30 shot I made with mirror lock up, remote release and a Meade ETX-90. The difference in the 60 and 90 probably doesn't matter too much, but the mirror lockup and remote release and a rock steady tripod can make a significant difference. The ETX-90 can be purchased right now from ScopeTronix for $199.

Click to expand...
It's a telescope, 60mm diameter main lens. Refractor means it uses a lens vs. a reflector that uses a curved mirror.

Even with a Sigma 70-200 f2.8 and a 1.4x adapter, the moon appears
pretty small. Is your image cropped big time?
Click to expand...
The image filled most of the frame, the setup I used made the scope about the same as a 1000mm lens.

Yes, images taken without the barlow don't have as much CA. The barlow has less CA than the 15mm eyepiece I have and produces about the same size image.

I was using mirror lockup and a remote. The moon was low and there was quite a bit of turbulance in the atmosphere, edges of the crators were a bit wavy when using the scope without the camera. What I really need is a more sturdy mount with a drive.

So the moon in the ETX-90 fills the frame using prime focus? I'll have to think about that. I do not want to spend that much since I have access to a 10 inch LX-200 at work (but that scope has to stay in the building, I can't take it home).

Yes, atmospheric conditions can mess up an otherwise excellent setup. The ETX-90 used with a 1.6x reduced field of view sensor and the meade "T" adapter with a standard Canon "T" mount will give an effective 2000mm (1250mm tube native focal length). Actually, you can't quite get the full moon in as you can see in my sample.

With the 10 inch, depending on the native focal length, you might get it all. Some are less than 1200mm and others are more, but there are adapters to reduce focal length. The 10" should give you dynamite moon shots with astounding clarity. You could also use "stacking" techniques to average and improve overall resolution. Some of the stacking software is incredibly easy to use and quite inexpensive.

Best regards,

Lin

The 'scope wouldn't be a Meade ETX-60, would it? If so, you've done a remarkable job cleaning up the chromatic abberation.
