I've had a corresponding report from Drogheda - same time, reported as being in the west from there.

 A bit more on this Smiley

I used the X-500 and a few lenses, only one of which was a zoom of sorts - actually a varifocal Vivitar Series 1 28-105 - difference being that you need to refocus after zooming as it doesn't maintain its focus across different focal lengths. Looking at the web renditions I may adjust the image gammas downwards a bit!

Not the greatest of photos, but photographed by me yesterday with a totally manual film camera and developed by me in the kitchen this afternoon Smiley  A very fulfilling experience!

Oh yes, sharpness and colour both fabulous!

For those interested in retro technology, I have scanned and posted my last ever roll of Kodachrome, the legendary film that gave us those nice bright colours. There's something about them that digital doesn't do quite so well!

Thought this might be of interest here. A friend was asking what the point of having a DSLR is when his compact camera takes such good 12 MP pictures. It's a good question, though I'm sure all here know that big pixels are better than small pixels. So I pitched my A700 against my Lumix FZ38 bridge camera that is the jack of all trades that I carry when travelling light.

Also, note how good the latest ACR 6.4 is at handling high ISO noise with the A700!

Faint, but it's a start!

Brilliant stuff - I take it Jackie will be doing a report at some stage?

Crikey, brilliant shot! I'd suspect the BBC might not be interested due to the danger element.

Very nice! I must get off to Portglenone Forest at some stage soon!

Hi Y'all,

Here's a collection of er, 800 or so snaps from my recent trip around some of the Southern states of the USA

Lovely shots Richard. Just to add a bit of technical info - you'll remember that the partial eclipse of 4th January was a case where the Moon's shadow missed the Earth by being too far North. Look at the focus of your anti-crepuscular rays and you'll see they point to the North of where the Wolf Moon is. This is because 14 days later, the Moon is now South of the ecliptic  as it was North at the time of the eclipse.

Orbital mechanics in action!

Well done Martin, that was a fitting end to the series.

I understand the criticism of the series and indeed I was discussing it with one of the producers who rang me about it, and I explained that I liked it a great deal on the basis that it was not pitched at my level. I'm a Sky at Night man on the basis that I want to hear from the Professors about their latest work, but that's not a starting point for Beginners, unless you want to frighten them away!

So for what the series set out to do, it id it well. Now we need it on once a month to maintain the interest that leads people to join societies and find their way up to "Sky at Night" level!

Beat me to it Richard! Yes, an excellent result Dennis, both with the eclipse itself and the front page!
