The super moon last night was a bit weird - I have never seen such an orange moon - in fact Orla commented that it looked like the sun.... Anyway hadn't planned on imaging it so all a bit rushed. Ended up taking photo through loft window balancing one legged on Sam's bed... ISO 800, 105mm zoom, 1/8 sec.... Two images show full FOV & 100% crop.. minimal processing - This was pretty much the colour it looked (sky was probably a little brighter)... It did look pretty big though at least during first 10-15mins..

Cheers,  John.

it was really red when it was quite low. I put a yellow filter on the scope to have a look. It filled the whole of the 6" and some.

Looked really Orange to me - In fact initially when it just started to peek up I thought it was lights switching on in the distance......

I took a similar image of the Moon, John, but I couldn`t get it right.  Like an idiot, I had the camera on manual focus but forgot, in haste, to manually focus it.  The trees were sharp and the moon was an orange blob.  Oh well, you can`t win them all .......

Because I did it all at the last minute I just left everything in Auto mode & hoped for the best. With hindsight I should have gone to manual shutter control & selected a much faster speed so the moon wasn't as over-exposed & to get some detail but then thinking about the foreground stuff (houses/ trees etc.) would have come out a lot darker... Would have also been nice to have a much longer lens so I could have zoomed in & made it larger but 105mm is the longest I have.

Oh well at the end of the day we both managed to see it & capture an image of the moment.

Well done John, I couldn't even get the thing to focus  :!

Cheers Mick,  I wouldn't say my focus was the best - I was hand holding at 1/8 sec.. whilst balancing on 1 leg....   :lol:

It certainly is an interesting colour.

There are some other pictures of the "supermoon" here:

An interesting one shows the change in size over a 2 day period.

...though that one is slightly misleading because the first two images are placed a bit low, and give the impression the size difference is larger than it actually is.

I was going to work out the difference in size on a ccd but i'll do that a little later.

We shall want to know the area covered per pixel at each stage between perigee and apogee  :twisted:

You really need to get a daytime job  :roll:
