seething prom animation

Posted By Alan Friedman
OK - last prominence image for today... promise!

I took the time to process three of my umpteen streams from yesterday morning to enjoy the subtle changes in this lovely firestorm over the span of 78 minutes. The three images are less subtle seen in animation:

Hi Robert -

A very sharp early image - great work!

glorious copernicus

Posted By Alan Friedman
Hi -

Copernicus and environs captured in nine images over nine minutes - the seeing varied some over that time, but at some moments it was quite good.

100 frames hand selected from each video stream and aligned multiple times to make each of the nine mosaic panels. The original image is quite large - reduced here to fit the Astromart size constraints.

Hi Robert -

Always nice to see great Jupiter images like this - thanks for posting it.

archimedes

Posted By Alan Friedman
Hi -

The area south of the Montes Spitzbergen centered on Archimedes (which could be a little brother to the grander Plato). The low sun angle illuminates many small "innie" and "outie" craters.

This was the first region captured from August 16th - the seeing was not as good as later that morning and with the deep shadows I found this a hard image to process.

Reduced here to fit Astromart specs - a link to the full resolution file can be found below the image on my website:

Astro-Physics 10" mak/cass

Posted By Alan Friedman
Hi -

I posted this to the solar system forum the other day - thought I would share it here too. This is Roland's 10" f14.6 with a 23% central obstruction set up on an A/P 900 mount and portable pier. I often mount a 4" traveler on the top dovetail bar for star parties - the contrast in focal length is great fun visually.

This is my primary planetary imaging platform - I use a Baader FFC or barlow for focal lengths from 7-12 meters, depending on the subject. Shown here is a 1.5" travel starlight auxilliary focuser which is a nice convenience for critical focusing on our coldest Buffalo winter nights.

from Davy to Arzachel

Posted By Alan Friedman
Hi -

An image of this famous and often imaged lunar vista, assembled from 10 streams captured on August 16 - approximately 100 frames stacked per segment. The low sun angle (making it very difficult to process) gives Ptolemaeus the appearance that it has been gone over with a ball peen hammer.

I have worked on this for a long time with many distractions and I think I've worked on it too much. This reduced version shows most of what was captured - a link to the full resolution file is posted below the image on my website:

thanks for looking!

the BIG picture

Posted By Alan Friedman
It wasn't until I saw Mark's post that I realized the connection between two of my recent pictures. I joined them and reduced the result in size to make this lunar walk a little more manageable.

Hope you enjoy!

between the rain and the cold

Posted By Alan Friedman
Hi -

This region of scattered rubble separating the Mare Imbrium and Mare Frigoris would be of little visual interest if not for it's famous and beautiful resident crater.

A mosaic of four images (approximately 100 frames used from each) captured with the A-P 10" mak/cass on August 16, 2006.

a very unusual observation

Posted By Alan Friedman
Looking at some recent lunar video I found an odd bright streak that appears on only a few frames.
I wonder what this could be?


best wishes and happy holidays!
