Northern Ireland has been enjoying some good weather! The night started a bit hazy but it gradually cleared nicely. I knew that at 1am to 347am BST I would need to image from my front garden which is very light polluted from street lights but I thought that for a full Moon, that wouldn’t matter too much.
I set up my Equinox 900mm f/7.5 scope on a tracking mount (Ioptron ZEQ25GT) and did a very rough polar alignment. I attached a Canon 5D2 to the scope with a large bore T2 adapter. I knew that the Moon would occupy about a third of the frame.
Initially I tried using Backyard EOS to control and focus the scope but it only works for long exposures and I had to abandon that and just use live view to focus and inspection of histograms and images to judge exposures.
I started off at ISO 100 and 1/250s and gradually, over the course of the eclipse pushed that up to ISO 2000 and 2 second exposures as the Moon got dimmer. With the tracking mount, I didnt have to worry about the Moon’s movement or long exposure times causing blurring.
Overall, I got some lovely images. My next door neighbour, Walter, came out near totality to watch along with me. It was strange how it went from a brightly moonlit night with few stars visible to a dark starry night!
The red colour is due to refraction of light through Earth’s dusty lower atmosphere but in image number 5 of the montage, you can see a bluish colour – this is due to refraction of light through ozone at the top of Earth’s stratosphere.
One of those evenings when everything worked well.
