Exclamation Article: Total Lunar Eclipse, 28th August 2007

Hi all

I've written an article about the upcoming Total Lunar Eclipse on the 28th August 2007.

It describes what a Lunar Eclipse is, When and Where you can see it, as well as Viewing Guides and Photography/Imaging Guides.

You can read the article in the IceInSpace Articles page, or directly by clicking the link below:

Total Lunar Eclipse, 28th August 2007 - Viewing / Imaging Guide

Please use this thread for discussions about the upcoming Lunar Eclipse!

Hide under the bed - scary!!!!!

Actually, being a weeknight, not sure where to go. Thinking of heading up to Macedon Ranges Observatory ( http://www.darksky.net.au/events.html ) and view/image from there. From where I work, that is closer (time wise) than going home!

There has been some discussion here in Perth already as the moon rises just as it enters totality, which affords some unique opportunities to capture the eclipsed moon in the belt of Venus. Some of us are now on the lookout for a site with a good eastern horizon that is not King's Park - and hoping it's not going to be cloudy!

Thanks for the feedback.

Nice image Bazz. The 2004 total eclipse was an early morning event (5am-ish) and I saw it out of my window to the West while driving to work. I took some binoculars with me and had a look when I arrived at work, but it was difficult to observe.

This upcoming eclipse will be my first where a) I know what's going on, b) It's easy to observe, and c) I have the technology to take pictures of it

Great article Mike, very useful. Like you this will be my first where it's at a good time and position and I have all the right equipment as well.

I'm really looking forward to it.

Cheers

Great Article Mike, I have created a link to it on our website.
We will be at Brunswick Heads to watch the full moon rise and the eclipse to follow shortly after. It will be a public event all are welcome especially those who cant quite grasp this amazing phenomenon. Lets all hope for clear weather. The last one was in between cloud cover in Sydney.

Thanks a lot for the article!
I am based in Fiji and wander if you have a chart about the visibility of the event here.

Hi Miki.

Fiji is GMT+12, the same as New Zealand, so the whole eclipse should be visible for you, starting just after moonrise.

Good luck and I look forward to your images/reports!

Weather forecast

As we are concerned about the weather for 28 August, I looked up Ken Ring's Almanac for 2007 and have attached his forecast for that date - looks good if he is correct.

OK a few questions here,

1. by switching the mount to track in lunar, that will that track the moon and give you star trails with longer exposures for totality, say F10 scope iso 400 or slower?

2. Under partial conditions what do you aim for - the bright section to focus or the "dark section"?

3. What part of the moon is best to focus on, the middle or the edge? Would this change throughout the eclipse?

gee I have taken the pills this morning!!

4. Now for a newbie to autoguiding - can you autoguide on the moon? don't laugh this is serious!!!!!

5. How would you "white balance" A modded DSLR for lunar shots?

6. How many will be throwing nearly all their entire imaging arsenal behind imaging this event?

Cool

G'day Y'all
Would of thought 1/2000 sec, 1/500 sec, 1/250 sec, 1/125 sec, 1/60 sec combination of the lens aperture and shutter speeds as the shadow progresses will be needed.
A fast shutter speed will use a larger aperture (small F-stop number) to avoid an under-exposed image. A slow shutter speed requires a small aperture (large F-stop number) to avoid over-exposure.

NO star trails from that

Long range forecast for next Tuesday looks good so far (for Sydney, at least ).

I would doubt it - your exposures are going to be under 4 seconds. You won't notice star trails in that time.

The bright section.

3. What part of the moon is best to focus on, the middle or the edge? Would this change throughout the eclipse?
The middle, but honestly it won't matter. The difference of a few hundred kilometres (from middle to edge) at a distance of 400,000 kilometres, won't be noticeable when focusing. Your camera should be set at practically infinity. It shouldn't change during the eclipse, except for the effects of the cooling glass. It might be worth re-focusing every hour or so, and lock focus in-between.

I don't know, but I honestly wouldn't bother. You can readjust using the hand controller if it starts drifting.

I don't know, but take the opportunity later this week/weekend to do some test shots and get it set correctly before next Tuesday.

hehe, mostly. Thought I have to borrow another camera (300D) to do what I want to do. I suppose I could use the digicams in a crunch.
