View Full Version : Lunar Eclipse 21st February

Here's a reason for staying up late (or getting up indecently early!).

It begins at 0035 GMT when the Moon enters the lightest part of the Earth’s shadow, the penumbra. Soon after the Moon will have a slight yellowish hue. At 0142 GMT the Moon starts to enter the dark core of the Earth’s shadow, the umbra. At 0301 GMT the Moon will be completely within the umbra – the ‘total’ part of the eclipse has begun. This is the time when it should have an obvious red colour. Mid-eclipse is at 0326 GMT and the total phase ends at 0352 GMT. At 0509 GMT the Moon leaves the umbra and the eclipse ends when the Moon leaves the penumbra at 0617 GMT. [This paragraph was 'borrowed' from AlphaGalileo.Org]

Now we just have to hope for clear skies.:D I'm in London, so the atmosphere is usually no help.:(

Always tend to miss this stuff because of cloudy skies, failing that it is the light pollution!

silly question time - I know you can't look at the eclipse as it will blind you, well from my understanding anyways however can you look at the eclipse through a lens? Will it cause any lens damage?

You're mixing up a solar eclipse with a lunar eclipse

Looking at the moon whether full,new or in shadow of the earth is fine.

Looking at a Solar eclipse can be very dangerous and you need to take a lot of precautions. However it won't damage your lenses (think about the number of pictures with a full sun on them)

Whether running a camera in liveview trained on the sun for a long time would damage the sensor I don't know and maybe others could comment

I've attached a picture made up from some of my E500 shots last time we had an eclipse in Wales - not too good as I only had the 150 at the time, but now I have the 70-300 and EC-14 :D:D:D

Cheers Andy, told you it was a silly question, lol how thick am I :o

Liking your pic, I've only got a 150 however I'm looking forward to seeing your pics with the 300 and EC14, those will be monsters :D

Hi Folk

Some details from the Royal Observatory

This lunar eclipse will be visible from Western Europe (including the UK), Western Africa, all of South America, and central and Eastern parts of both the USA and Canada. This lunar eclipse lasts from 00:30 until 6:20 GMT – basically, throughout the night!

This means that for most of us we need to think about being up late on the Night of the 20th. Just wanted to post that people didn't miss it by thinking it was the night at the end of the 21st instead of the start of it

Regards
Andy

Thanks for the heads-up on the eclipse - I haven't photographed one of these digitally yet, although I did do one years ago with a film camera. I remember being surprised how fast the moon moved - quickly enough to blur the images in the long exposures I was doing, as I found out when I got the film back!

Forecast for early next week is good ATM, so let's hope for clear skies!

I have just purchased a Celestron 60 SLT telescope (beginners model) and various accessories. I intend to attach one of my e510's to the telescope. I also have the 70-300 and the EC20 to go on the other E510.

Here is a shot of the moon that I took several nights ago.

I have not processed the image, other than cropping.

Hi Hugh

THis should not be an issue - the trick that many people forget (and I've learned the hard way back in film days when I used to run my Pentax with a 500 mirror or through my birdwatching telescope [hmm must see if I can get an adaptor]) is that you are not exposing for that mass of black you see around the moon - let it be. You are exposing for the bright white blob in the middle.

Also depth of field should not be a massive issue so you don't need to stop down much at all, just enough to move into th eoptimal range for the lens you are using e.g. I'm going to be using the 70-300 @ 300 some I'll move it up to about f11 max

Then pick a not too high ISO - I'll tend to about 200-400 myself and will probably end up somewhere in the 1/125 to 1/10 range as I mess around with various settings. Long enough to need a tripod definitely, but you shouldn't need to worry about the moon moving too much.

There are some great websites that give a lot more detail on how to do it a lot better than I probably will - Hmm living in Wales the biggest liklihood is that we'll be under about 2 layers of cloud and it will be raining from both !!

I have just taken a quick shot of the moon with my E510 and the Celestron 60 SLT telescope.

I did try to use the EC-20, but it made the image too dark. It would have been a good image as the whole image filled the frame.

You've definitley inspired me to hun down an adaptor for mine ... Excellent !

Not that I know anything about telescopes (or photography :p ), but what telescope do you have?

Jim -

For a quick shot I bet your more than pleased with the result.

Yea, it is very cold out side. I took about 15 images. Most at 1/160, but some at 1/80. Did not take too long.

I really no nothing about astronomy. I just like looking up. I know the moon, and mars (I think its the birght orange star like thing).

I purchased the telescope for the tracking motor mount. My local camera shop forgot to order me a motorised mount for my tripod, so the sold me a telescope with a mount. The telescope was cheaper! Not too bad for £100 me thinks.

I am pleased with the photo, especially when the images that the EC20 + 70-300mm shots took. The EC-20 and 70-300 cost @ £600ish.

i would love to be up for this but i start work at 6am so need to sleep :( i hope to see some lovely pics though :D.

It depends on the telescope and the size of the eyepiece used.

As suspected in my prior post in this thread Wales was under a whole load of cloud at the time ( what a surprise:rolleyes:)

So here's one I took a couple of days before on my supposed practise session using the E510, 70-300 (at 300) and EC-14 giving an EXIF focal length of 425 or a film equivalent of 850. Shot taken at f11 1/350

http://e-group.uk.net/gallery/data/500/moon1.jpg (http://e-group.uk.net/gallery/showphoto.php/photo/3057)

This is a straight crop out of the centre of the frame in 4/3 aspect ratio.

This is no where as good as John Baker, but I was still pleased to get something that I can look at myself with the hope of doing something interesting next time an eclipse comes around

Very nice image.

I cheated....I used a telescope.

Nice detail. I have to convert my images to BW, as my telescope adds CA.

John.

Good advice re the CA. I didn't think and you are right it does help a little

Not enough in my case to warrant reposting, but if I was to use it anywhere I would remember that nugget

Cracking pictures, both with and without the telescope.
