better late than never - Theophilus December 2005

Posted By Anthony Wesley

I thought I'd lost this, I spent a lot of time working on an image of Theophilus in late December last year and then never got around to posting it... when I remembered it a few months later I couldn't find it anymore :-(

Anyhoo, I just stumbled across one of the final images in my Jupiter data, how's that for mis-labeled?

Details (as best I can remember):

10" f/6 newtonian
Dragonfly Express firewire camera
lots of frames (maybe 6000 or so?)
Captured under Linux with Coriander, processed under Windows with Registax
and Astra Image.

cheers, Bird

Very clear image, given the conditions.

Saturn December 18

Posted By Anthony Wesley

Despite the low altitude at transit of 38 degrees and lots of smoke haze from fires around SE Australia I was quite happy with this image. The smoke lowered transparency to about 50% of normal.

Details:

13.1" f/5.5 newtonian + powermate (FL=11000mm, F/33)
R/G/B Astronomik filters
R/G = 2 minutes @ 14fps
B = 2 minutes @ 10fps

Dragonfly Express mono firewire camera
captured under linux with Coriander
Processed under Windows with registax4, Astra Image and The Gimp

Saturn 28 December 2006

Posted By Anthony Wesley

On the evening of December 27/28 I set up in a dark site to have a go at saturn. The transit time was around 4am local time, which also corresponded to the best seeing that night. Despite the low altitude of 39 degrees at transit I was happy with the quality of the data I captured.

Details:

13.1" f/5.5 newtonian + TV powermate for FL of 11000mm (F/33)
Losmandy G11 mount + Gemini
Astronomik RGB filters + filter wheel
PGR Dragonfly Express monochrome firewire camera
red/green: 3 minutes each @ 20fps
blue: 3 minutes @ 12fps

captured with Coriander for Linux, processed with ppmcentre,
Registax4, Astra Image and The Gimp.

Image was resampled to 150% for processing.

There are some artifacts visible, but overall I'm happy that this is about the best I can get from Saturn at the moment.

Jupiter from December 28 2006

Posted By Anthony Wesley

I had originally written off this data, but today I processed it for something to do...

This is Jupiter, low in the east imaged just before dawn. 1000 frames each of R,G,B - I stacked them all as they were all uniformly bad :-)

13.1" f/5.5 newtonian + powermate for F/33 (11000mm focal length)
PGR Dragonfly Express camera

ps oops, it's actually December 27, not 28 :-)

Jupiter + Oval BA, Jan 11 2007 1811UTC

Posted By Anthony Wesley

The seeing this morning was truly awful, maybe 1 or 2/10. A fire was burning about 10km away at lake george, and I was looking right over it.

Last night was amazingly hot - at sunset the temp was 35C, and at midnight it was still 28C. The minimum for the night was 21C at about 5am.

And it was followed today by our 2nd hottest day ever - 40.5C. Yowzers!

Anyhow, here's an image of Jupiter from this morning at about 5:11am local time. Features to note are the transit of Io, and Oval BA (AKA Red Jr).

This is an image from a few days ago, the seeing was not that great but it was a very nice sight to see.

Image details: 3500 frames @ 40 fps + red astronomik filter.

Lunar: Archimedes

Posted By Anthony Wesley

One more from the 10th, this is Archimedes, a stack of 1500/3500 frames, 9 point alignment in registax.

There are some joins still visible, registax had a lot of trouble with this one for some reason...

Saturn from Lostock NSW Australia, 19th Jan

Posted By Anthony Wesley

Seeing at Lostock on Friday night was unbelievably good, I had the best views and images of Saturn so far this year, possibly the best ever despite the low altitude of 40 degrees.

Here's one processed run - normally I have to combine data from several runs to get this sort of result, but not this time!

Scope Details: http://www.acquerra.com.au/astro/lexx.html
Capture Details: 3 minutes each of R,G,B @ 25 fps

Lunar: Mare Serenitatis and Posidonius

Posted By Anthony Wesley

Last night I tried prime focus imaging for the first time with my DX camera, the seeing was very steady so I captured several runs on an almost first-half moon.

This is a part of the moon I can't normally image when I'm at home as the seeing is too unsteady in the early evening, but I'm staying near the pacific ocean for a few days and the seeing is very nice.

Scope details: http://www.acquerra.com.au/astro/lexx.html (no powermate this time)
Image details: 4 minutes @ prime focus (f/5.5), no filters, 50fps. Minimal gain.
