More love and joy on Christmas Day from Roma, QLD

Inspired by adman's expedition west of Brisbane to escape the clouds and join in the fun, I decided to do the same yesterday afternoon. I checked Skippysky and the closest location to Brisbane that was forecasted to have no cloud at all was near Roma (QLD).

After a six hour drive there, five hours under the amazing stars with a herd of cows for company, and a seven hour drive home - here's my handiwork:

1. Widefield of Lovejoy, the Milky Way and LMC/SMC. It's fairly representative of the naked eye views, except for the colour, very faint stars, and fine detail in the nebulosity. 2x 301 sec ISO 800 f/4 using a Canon 5DmkII + 14 mm f/2.8 on an Astrotrac Travel System.

2. Lovejoy and the Milky Way. 1x 30 sec ISO 800 f/1.4 using a Canon 20D + 24 mm f/1.4 on a fixed tripod.

3. Self portrait while shooting some DSOs. 1x 30 sec ISO 3200 f/2.8 using a Canon 20D + 14 mm f/2.8 on a fixed tripod.

4. Comet fading away during twilight. 1x 30 sec ISO 400 f/4 with the 5DmkII + 14 mm on Astrotrac.

This was the first time I saw the Milky Way cast a shadow... the sky was unbelievably dark! At home, I get a sky fog middle-histogram peak after 45 secs at f/4 and ISO 800... according to my test shots last night, I could have gone for over 20 mins there!

Thank you Santa for my best Christmas ever!

I like that 1st image the best.

One of the best I have seen of it so far.

It seems this comet is best with a fast widefield lens and tracked.

Greg.

Thanks everyone - it was a magical sight from a really dark site

The first super-wide-field is a universal favourite. The detail is very good with round stars in the centre viewed at 100%, but unfortunately it's rather noisy due to the continuous 5 minute exposures on the SLR. I'm going to run off a few dark/flat/bias frames to generate the final image - can't wait to print it out BIG.

Greg - I suspect you're spot on re tracking since the dynamic range of the twilight scene is surprisingly high. Here's the histogram from one of the unprocessed subs - foreground silhouette on the left, main yellow/green sky background in the lower third, and stars and nebulosity detail in the upper two-thirds. I'd love to shoot wide fields with a cooled CCD with large pixels on a "full-frame" chip (e.g. the KAI-11000 cameras) but they're still out of my price range.

Liz - I never thought I'd say this, but I have to thank the clouds in SE QLD because without them I wouldn't have driven out so far

Thanks David - your great work with the Astrotracs and positive comments helped persuade me to go for it. That and someone offered me a virtually brand new unit at a bargain price

This is probably a sacrilegious thing to say around here, but I think I'm going to sell my EQ6 soon and just keep the AT

Awesome shots Dave! Although I had my 17-40 on the camera, I only took mine at 40mm. Looking at yours and Terry's widefields makes me wish I had done the same.

Cheers
Adam
