Lunar eclipse

[ND66]

Thanks to the fact that it is COLD tonight (right now 3F - minus 16C and that's without the wind factor), we have clear skies and great view of the lunar eclipse.

Didn't check all my pics yet, here is a couple quick ones.

I need to warm up, brrrrrrrrrr.......

It was freezing here as well.. my shots didnt turn out that good. but none the less here are a couple




what do you think caused all this bad purple lighting at the top of the picture?

Well, I can see your exposure time was quite long and assume that the aperture must had been set higher then 22, no?

I can’t see the EXIF data, but I’d try different aperture setting.

weak light from a streetlamp, perhaps even parts within the camera running hotter and affecting the sensor when taking really long exposures..

I would assume the sensor thing you said, because there are no street lights where they live.

I read a very long tutorial last night after I got home about how to do star trails, and i think ive learned a lot in the last day, so next time i try i'll be more informed before going out.

heres the exif data

Was your White Balance set to Auto?

I think it was Fluorescent.

Anyone have a flashlight or led light ? Would only take a short exposure during the shot .

[ND66]

I think it was Fluorescent.

Exif says Tungsten, missed that before....

I think Daylight would be a better choice.

Also, check this thread on shooting moon HERE:

I'm learning myself.

PS. Note where they talk about the blue cast....

...I would use the 80-200mm because, of the 3 lenses, I think that this will produce the least amount of CA (Chromatic aberration, "the ugly purple ring"). and watch out for ghosting, most of the time I have not had issues with ghosting. ...

CA shows up mostly at high contrast edges stars, moon- the purple "ghost" could be from an internal reflection but i did not see it on other images. If it was just a one off then external light is the likely cause. Low dispersion glass is used to minimize CA in the lens. THe Canon FL Flourite lenses are an example. In telescopes Apochromatic is used to describe the use of LD glass. Also, the bright fuzz on the moon is likely sensor bloom from overfilling the "light buckets" of each CCD element. Switch to the smallest spot metering you can do and work from that with the histogram display on the camera.

I'm betting it's light from some component in the camera (like a diode) or from the chip itself.

I would have tried to get a shot of the eclipse, but it was overcast with freezing drizzle.

Here's a couple from one last year:
