an old mars

Posted By Alan Friedman
I hope those of you who are bravely following mars back into the single digits of angular diameter will forgive this posting of an image from November. I had decided not to process it since the seeing was very poor. But weeks and weeks of no seeing and no observing has brought me back to my last look at mars - captured four weeks and four feet of snow ago.

best wishes -

work in progress

Posted By Alan Friedman
Hi all -

Yesterday officially made our current streak of sunless days (so many I've lost count) the longest in Buffalo since 1921. I thought i would celebrate by posting this template for my mosaic in progress.

This sketch is composed of single video frames surrounding the processed frames containing Plato and the Alpine Valley. I made this as a reference to consult as I process the 28 streams that will be used for the final image. It is shown less than half original size.

Should take a while to complete - but hey, it's a long winter! 8)

cheers -

saturn at opposition (almost)

Posted By Alan Friedman
Midnight in mid-winter is usually not a good candidate for steady skies here - but I ran into a brief period of good seeing Saturday night - six days before saturn reaches opposition.

750 frames from 4500 were used for luminance with the 10" mak at f45 and DMK camera with no filtration. RGB images were captured at f32 and resized.

Alpine Panorama with Plato

Posted By Alan Friedman
Next week many eyes will toward the Italian Alps and the Winter Olympics in Turin. This view also shows an Alpine vista - but here the snow is only sunshine.

Assembled from 20 streams captured on August 25 of 2005 through my 10" mak at f30 (reduced here about 65%). Altogether about 120 stacks were aligned and combined to make the mosaic.

Bravo, Robert - both are excellent pieces of work.
Thanks for sharing them here -

Hi Robert -

Still a very lovely and well processed image. Maybe as saturn moves into spring and the evening sky it will hold still for sharper details.

Thanks for posting it -

new saturn activity?

Posted By Alan Friedman
I had a few minutes to image saturn before the snow last night in fair seeing. On looking at one of the unfiltered streams this morning I noticed what might be a small bright region in the south equatorial belt. I haven't had time to look carefully at the other streams to confirm rotation of this area - did anyone else pick this up?

thanks -

a bit of saturn weather

Posted By Alan Friedman
Hi - Here is an RGB image showing a small bit of saturn weather - the square box is the remnants of the fading white storm, the oval area shows the two small bright regions in the South Equatorial Belt. 800 frames used from a four minute window centered on 3:23 UT on March 2.

Moving Shadows

Posted By Alan Friedman
Thanks for the comments on my recent Saturn image. This has been a hard season for sharp images of Saturn - I hope the second half of the apparition offers more opportunities.

I combined my three attempts into a movie showing three months of changes in the appearance of saturn from earth. Nicely shown are the movement of shadows cast by the both the rings and the planet's disk and also the brightening of the rings as the planet reaches opposition.

I hope you enjoy it!

solar gaze-elle

Posted By Alan Friedman
Mike posted a fine image of today's large prominence. This one was a little smaller, but also interesting - a solar gazelle grazing on small prom shoots at the sun's limb.

cheers-
